DESCRIPTION:Speakers: Paweł Siegmund (NCBJ)\nThe high precision and vast 
 volume of data from upcoming galaxy surveys—such as Euclid and the Rubin
  Observatory Legacy Survey of Space and Time (LSST)—and Cosmic Microwave
  Background (CMB) experiments like the Simons Observatory\, will enable th
 e use of CMB gravitational lensing potential measurements and their cross-
 correlations with the surveys to shed light on observed cosmological tensi
 ons. These datasets will allow us to constrain extensions of the standard 
 cosmological model with unprecedented precision. In this talk\, I will pre
 sent an investigation into the systematic effects that can have influence 
 on robustness of constraints on modified gravity models and dynamical dark
  energy scenarios. Specifically\, I will focus on likelihood-based analyse
 s and the biases introduced by photometric redshift errors in galaxy surve
 ys\, residuals of Galactic foregrounds in CMB anisotropy maps\, and lensin
 g magnification effect.\n\nhttps://events.ncbj.gov.pl/event/436/contributi
