In this talk, I will present an overview of my research on Dark Matter (DM). I will begin with a brief introduction to the study of DM across different approaches, before focusing on Cannibal DM produced via the freeze-in mechanism in the early Universe. I will discuss the non-trivial thermal dynamics of this scenario and the importance of tracking the DM temperature evolution. I will then...
Low Surface Brightness Galaxies (LSBGs) are defined as galaxies with an average central surface brightness, 𝜇(0,r), below the typical level of the night sky. LSBGs are estimated to contribute less than 1% to the luminosity of the local observable universe; however, their contribution to the total number density of galaxies is estimated to be around 40% to 50%. Exploring the standard evolution...
This work presents the development of a comprehensive computational framework for modeling fusion and fission processes in heavy and superheavy nuclei (Z ≥ 90). The framework is based on the Warsaw Macroscopic-Microscopic Model (WMMM), extended to incorporate multiple shape parameterizations, including the traditional beta parameterization and the Fourier-over-Spheroid (FoS) approach, which...
Dark matter interactions are traditionally probed in the non-relativistic regime characteristic of cold DM in the present-day universe. However, this strategy is insufficient for probing a class of important thermal DM targets for which non-relativistic scattering rates are highly suppressed. This opens an unexplored region of parameter space and motivates the development of detection...
In this seminar, I will present a study of Vector Boson Scattering (VBS) at the Compact Muon Solenoid (CMS) experiment at CERN, focusing on same-sign $W^{\pm}W^{\pm}$ scattering and its sensitivity to physics beyond the Standard Model. The analysis targets the leptonic final state with two same-sign charged leptons, two neutrinos, and two forward tagging jets, providing a clean handle on the...
Strong gravitational lensing, a phenomenon where the gravitational field of a massive foreground galaxy distorts and magnifies the light from a distant background source, provides a unique astrophysical laboratory. It uniquely bridges studies of the very large and the very small, enabling simultaneous investigation of the internal structure of galaxies and the global geometry of the universe....
High-precision calculations of Higgs boson observables can be used to constrain models of Beyond the Standard Model (BSM) physics. Motivated by the non-observation of light BSM particles at the LHC, in this talk I will discuss a renormalization scheme for precise predictions of Higgs boson decays in the presence of moderately heavy BSM physics at the 1-loop level. I will cover the basics of...
I will introduce the high-energy limit of collision events in QCD, as formulated within the Color Glass Condensate (CGC) effective field theory, which provides the established framework for such studies. In this framework, scattering processes are typically described using the eikonal approximation, in which highly energetic partons propagate along straight-line trajectories through the target...
Perturbative calculations within the theory of Quantum Chromodynamics have always been challenging, as it forces us to deal with composite objects in asymptotic states during scattering processes. These objects, called hadrons, exhibit complex, nonperturbative dynamics. Many frameworks that describe hadron dynamics arose in the past several decades, verified extensively in experimental setups...
Understanding how star formation history (SFH) models influence galaxy evolution is still a major challenge, especially for quiescent galaxies (QGs). SFH dictates not only stellar mass assembly, but also governs quenching pathways and timescales. JWST's unprecedented sensitivity enables us to resolve discrepancies in SFH modelling, particularly for recently discovered dust-rich QGs at high...
In the coming years, deep wide-field surveys such as the Legacy Survey of Space and Time will dramatically expand the known population of low surface brightness galaxies (LSBGs), enabling statistical studies and reducing selection biases. This will allow LSBGs to play a central role in addressing key questions in cosmology and galaxy evolution, including the nature of dark matter halos, the...
