Relativistics effects in cosmology

Jaiyul Yoo, University of Zurich

Precision measurements in current and future galaxy surveys bring in new challenges, demanding substantial advances in theoretical modeling. I will discuss the recent theoretical advances in using the relativistic effects in cosmology. Compared to the Newtonian effects, the relativistic effects are significant on large scales, in which modified gravity theories deviate from general relativity and the fingerprint of the inflationary epoch remains in its pristine form. I will discuss how the subtle relativistic effect in cosmology can be used to test general relativity and probe signatures of the early Universe.
