Identifying galaxy me rgers in large datasets is a difficult task due to their irregular and hig hly dynamic morphologies. In this seminar I will discuss some of the most common methods for identifying galaxy mergers through visual methods\, sta tistical approaches\, kinematics\, and machine learning.\nI will then disc uss some of the early results from my PhD research starting with a review of how morphologies are quantified. These early results compare statistica l merger classifiers to a suite of machine learning methods developed by M argalef-Bentabol et al. 2024. For this project\, a Monte-Carlo Markov Chai n was used to optimise the classifier performance. I will show that statis tical techniques can achieve similar precision to machine learning methods but lack completeness in their merger classifications. In future work\, u nsupervised learning may be used to improve the completeness of these clas sifications to produce a highly efficient and reliable merger classifier f or use on large surveys.\n\nhttps://events.ncbj.gov.pl/event/382/contribut ions/1841/ LOCATION:NCBJ Room 207 URL:https://events.ncbj.gov.pl/event/382/contributions/1841/ END:VEVENT BEGIN:VEVENT SUMMARY:Quark-gluon plasma in magnetic fields DTSTART;VALUE=DATE-TIME:20250605T071500Z DTEND;VALUE=DATE-TIME:20250605T081500Z DTSTAMP;VALUE=DATE-TIME:20260521T051319Z UID:indico-contribution-382-1837@events.ncbj.gov.pl DESCRIPTION:Speakers: Patrycja Słoń ()\nAn impact of the electromagnetic field in the presence of strong interactions is usually not considered\, as it typically plays a negligible role. However\, the electromagnetic fie ld becomes visible when its magnitude is characteristic for strong interac tions. It is not accessible experimentally to create such a strong magneti c field. Nevertheless\, it is expected that a field of a very large amplit ude can briefly arise in relativistic heavy ion collisions\, and be sustai ned by induced electric currents in the quark-gluon plasma created during the collision of ions. The project aims to analyze the electromagnetic fie ld generated in relativistic heavy ion collisions. The research project wi ll include a discussion of aspects that have not been analyzed so far\, su ch as formulating the problem of generating an electromagnetic field as an initial value problem\, and analyzing the behaviour of the quark- gluon p lasma in such a field. The main goal is to take into account non-equilibri um effects by properly setting the initial conditions.\n\nhttps://events.n cbj.gov.pl/event/382/contributions/1837/ LOCATION:NCBJ Room 207 URL:https://events.ncbj.gov.pl/event/382/contributions/1837/ END:VEVENT BEGIN:VEVENT SUMMARY:Freezing-in Cannibal Dark Matter DTSTART;VALUE=DATE-TIME:20250529T071500Z DTEND;VALUE=DATE-TIME:20250529T081500Z DTSTAMP;VALUE=DATE-TIME:20260521T051319Z UID:indico-contribution-382-1833@events.ncbj.gov.pl DESCRIPTION:Speakers: Juan Esau Cervantes Hernandez (NCBJ Warsaw)\nSeclude d dark sectors\, while offering an appealing framework for dark matter pro duction through internal interactions\, lack direct experimental avenues.

I wil l then connect the dark sector to the Standard Model via a feeble coupling to the Higgs doublet\, within a freeze-in production scenario that could also account for the origin of the dark sector itself.

QCD\, becomes highly non-perturbative at th e scales typical of hadron size\, hence describing these hadrons as bound quark systems from first principles is challenging. Experimental observati ons have driven some progress\, leading to the discovery of nearly 30 exot ic hadron candidates. It is the pattern of one unexpected result after ano ther\, with the emergence of desperately few connections\, that has charac terized the last 20 years of experimental studies in this field. The LHCb\ , with its unique capability to cover the large heavy-quark production cro ss-section at the LHC\, offers an great window of opportunity to explore h eavy hadron spectroscopy\, in both the conventional and exotic sectors. \ n\nThis presentation is a synopsis of our work in search of QCD exotica in new decay modes of B-mesons in order to improve the previous measurements and make new observations of these incredible anomalies. I will present c urrent results regarding higher charmonium states which are not fully unde rstood and the possibility of observation of such states in previously un- measured decay modes of B meson in the LHCb data\, collected from Run 1 (2 011-2012) and Run 2 (2015-2018) in proton-proton (p-p) collisions.\n\nhttp s://events.ncbj.gov.pl/event/382/contributions/1825/ LOCATION:NCBJ Room 207 URL:https://events.ncbj.gov.pl/event/382/contributions/1825/ END:VEVENT BEGIN:VEVENT SUMMARY:On the Photon-Jet Production.

With an increasing influx of observations\, we are encountering cosmic objects that challenge our theoretical frameworks. Especially\, recent studies reporting abnormally high gas and dust reserv oirs in the galaxies challenge our current prescriptions about dust format ion in the early Universe.\nIn this work\, we make use of chemical evoluti on models to probe the evolution of gas and dust within star-forming galax ies at a redshift of ~ 5\, observed by the ALMA Large Program ALPINE. Thes e galaxies were formed just one billion years after the Big Bang\, which d enotes a crucial phase when the Universe underwent transformation from the primordial galactic formation to the onset of the peak of cosmic star for mation rate density. We attempt to match the observed dust content and sta r formation rate of these galaxies by considering different dust productio n mechanisms\, including Type II supernovae\, asymptotic giant branch star s\, and dust growth within the ISM.\nOur models successfully reproduce the gas and dust content in most of these primordial galaxies\, indicating du st production primarily through SNII and gas/dust removal via galactic out flows and moderate inflow of primordial gas. However\, a fraction of galax ies show a rapid dust build-up in a short time-frame (~ 20 - 100 Myr). Thi s fast dust production might be partially explained by adopting a top-heav y initial mass function\, thus favouring the formation of more massive sta rs and a more rapid stellar evolution. I will also discuss the role and sy nergies between ALMA and JWST in advancing our knowledge of chemical enric hment in the early Universe.\n\nhttps://events.ncbj.gov.pl/event/382/contr ibutions/1796/ LOCATION:NCBJ Room 207 URL:https://events.ncbj.gov.pl/event/382/contributions/1796/ END:VEVENT BEGIN:VEVENT SUMMARY:Hunting the invisible with ALMA: the path for the first measuremen t of cold gas and dust in quiescent galaxies.

Amongst the many amazing discoveries\, this couple of t elescopes is deeply revolutionazing our understanding of galaxy evolution by unveiling a population of galaxies with very low star formation\, or qu iescent\, that contains copious amount of cold interstellar medium. These observations\, althoug still rare\, are changing the current paradigm for the formation of quiescent galaxies\, possibly even mining their in-use de finition.\nIn my previous work\, I used the state-of-the-art suit of cosmo logical simulations SIMBA to tackle the physical processes generating dust -rich quiescnet galaxies up to z~2\, comparing the effect of internal and environmental mechanisms for star formation quenching on the evolution of the ISM content. We find in SIMBA indications that dust grains can survive for much longer than expected\, depending on the balance between the grow th rate and the rate of grain destruction operated by the active galactic nucleus.\nTo test these results\, we requested time at the ALMA sub-mm/rad io interferometer\, which was awarded to us with high priority.

As the QGP cools\, it tr ansitions into the hadronic matter we observe today. In laboratory setting s\, small-scale "Big Bangs" are created through high-energy heavy-ion coll isions\, which heat the hadronic matter above the transition temperature\, approximately 150 MeV\, resulting in the formation of the QGP. Direct pho tons serve as unique probes in high-energy proton-proton and nucleus-nucle us collisions due to their weak interaction with the dense and hot quark-g luon medium. These photons escape the medium unaltered\, providing undisto rted information about the collision's evolution.\n In the ALICE experime nt at the Large Hadron Collider (LHC)\, photons from lead-lead collisions are measured using techniques such as the Photon Conversion Method and Ele ctromagnetic Calorimeter. The Photon Spectrometer (PHOS)\, offering high-p recision photon detection\, was used for our analysis (with Run 2 data in Pb-Pb collisions at √sNN = 5.02 TeV) to measure inclusive photons and si mulate decay photons\, aiding in the derivation of direct photon spectra.

The Color Glas s Condensate (CGC) effective theory has been developed and used to study p articularly high-energy dilute-dense collisions. One of the main approxima tions adopted in the Color Glass Condensate is the so-called eikonal appro ximation\, which amounts to neglecting power-suppressed corrections in the high-energy limit. This approximation is well justified for asymptoticall y high energies. However\, corrections to it might be sizable in practice\ , in particular at the Relativistic Heavy Ion Collider and the upcoming El ectron-Ion Collider. Therefore\, we need to bring precision in theory to a nalyze the upcoming data from the colliders. For this\, we have to compute observables like scattering cross sections beyond the leading order of en ergy. Deep inelastic scattering (DIS) is one of the clean channels used to study CGC beyond eikonal order. \nIn my talk\, I will briefly review the eikonal approximation and how to go beyond eikonal order. Furthermore\, I will present its application to semi-inclusive deep inelastic scattering ( SIDIS) and Inclusive DIS. Specifically\, I will present computations of ne w contributions to the cross-section of SIDIS at next-to-eikonal accuracy stemming from the t-channel quark exchange\, by including the effect of th e quark background field for the target and obtain its relation to Transve rse momentum dependent (TMD) calculations in small-x limit.

While numerous strongly lensed distant galaxies and quasars have been cataloged\, the strong lensing of explosive transie nts offers new scientific possibilities. These opportunities range from re fining measurements of cosmological parameters and detecting dark matter\, to testing fundamental physics. Particularly\, the long wavelengths of GW s suggest that wave optics effects are crucial in some instances\, potenti ally leading to novel uses of these lensing phenomena. With the next gener ation of GW detectors expected to enhance sensitivity tenfold\, the observ able volume of the universe could expand by a thousandfold\, substantially increasing detection rates of lensed GW signals. This surge in data provi des a unique platform to examine critical physical theories\, such as the properties of gravitons\, by studying strongly lensed gravitational waves. \nIn this work\, we investigate constraints on the graviton mass by analyz ing strongly lensed GW signals from typical binary black hole mergers. We simulate the response of next-generation ground-based GW detectors\, such as the Einstein Telescope\, to better gauge the potential of upcoming obse rvations. Our analysis assesses the capacity of future GW data to place me aningful constraints on graviton mass\, thereby offering fresh perspective s on the nature of gravity at cosmic scales.

Estimating the lensing potential field and delensing the CMB maps of high sensitivit y experiments are crucial for improving cosmological measurements. However \, one of the main obstacles for these tasks is the presence of foreground emissions from our own Galaxy. In this talk\, I will discuss about CMB we ak lensing reconstruction methods and the impact of galactic foreground em issions.

Decays of these muons in the beam pipe will produce a high-energy muon neutrino beam. The energy and intensity of the beam\, as well as its well-known energy spectrum\, provide a unique o pportunity to study neutrino properties and interactions\, potentially unc overing new physics beyond the Standard Model.\n\nIn this talk\, I will di scuss the prospects for detecting new mediators that couple predominantly to neutrinos with masses in the 1 MeV to 100 GeV range with low coupling s trengths. Such a neutrinophillic mediator\, which could couple to the dark sector\, is a well-motivated candidate for opening new avenues in the sea rch for neutrino portal dark matter. The corresponding signature would inc lude neutrino charged-current scattering events associated with positively charged muons.\n\nhttps://events.ncbj.gov.pl/event/382/contributions/1756 / LOCATION:NCBJ Room 207 URL:https://events.ncbj.gov.pl/event/382/contributions/1756/ END:VEVENT BEGIN:VEVENT SUMMARY:Microlensing of continuous gravitational waves DTSTART;VALUE=DATE-TIME:20241107T081500Z DTEND;VALUE=DATE-TIME:20241107T091500Z DTSTAMP;VALUE=DATE-TIME:20260521T051319Z UID:indico-contribution-382-1755@events.ncbj.gov.pl DESCRIPTION:Speakers: Sreekanth Harikumar (National Centre for Nuclear Res earch(NCBJ))\nThe direct detection of gravitational waves (GWs) by the LIG O Science Collaboration marked the beginning of a new era in astronomy\, a llowing us to probe previously inaccessible realms of the universe. Among the most exciting prospects in this field is the detection of gravitationa lly lensed GWs\, which could reveal valuable insights about intervening ma ss distributions in space. While much attention has focused on detecting l ensing in GWs from merging compact binaries\, little exploration has been directed toward the lensing of GWs emitted by isolated neutron stars. Thes e GWs are continuous and monochromatic\, differing significantly from the transient "chirp" signals we typically observe. In this talk\, I will disc uss our findings on the lensing of continuous GWs by dark mini-halos and d emonstrate how the relative motion between the lens\, source\, and observe r can produce a distinctive microlensing pattern. This work opens new aven ues in the study of GW lensing and could provide unique insights into the nature of dark matter besides enhancing the detectability of a signal.\n\n https://events.ncbj.gov.pl/event/382/contributions/1755/ LOCATION:NCBJ Room 207 URL:https://events.ncbj.gov.pl/event/382/contributions/1755/ END:VEVENT BEGIN:VEVENT SUMMARY:Evolution of the ISM in quiescent galaxies DTSTART;VALUE=DATE-TIME:20241031T081500Z DTEND;VALUE=DATE-TIME:20241031T091500Z DTSTAMP;VALUE=DATE-TIME:20260521T051319Z UID:indico-contribution-382-1754@events.ncbj.gov.pl DESCRIPTION:Speakers: Krzysztof Lisiecki (NCBJ BP4)\nUnveiling the routes galaxies take to quiescence is one of the most open challenges in galaxy e volution. While the most of studies focused on characterizing quiescent ga laxies (QG) across cosmic time through their stellar properties using opti cal/near-infrared (NIR) data\, the mid-infrared regime was only recently e xamined thanks to the advent of JWST. The need to understand the MIR emiss ion in QGs has been emphasized due to recent discoveries of a peculiar pop ulation of quiescent\, but dust-rich galaxies at high-redshitts (z>0.5-3).

The DDM utilizes the dipole variable as an authentic shape parameter to describe the configuration of the colliding heavy ions\, with shape param etrization performed at the neck region. This allows for the optimization of the deformation space and the exploration of previously unattainable sh apes.\nIn this talk\, a new method for predicting the probability of fusio n of superheavy elements will be presented. The approach uses a random wal k algorithm\, in which the shape evolution is governed by the density of s tates above the multidimensional potential energy surface (PES). The PESs were calculated within the latest version of the Warsaw macroscopic-micros copic model [1]\, with rotational energy included. \nThree cold fusion rea ctions will be examined in detail: 48Ca+208Pb\, 50Ti+208Pb and 54Cr+208Pb. The calculated probabilities of fusion for these reactions will be shown. The influence of angular momentum and excitation energy on ratios of symm etric and asymmetric divisions will be demonstrated. Future improvements t o the method will also be discussed.\n\n[1] T.
