Unbiased Bayesian Inference of Peculiar Motions of Galaxies from Type Ia Supernovae Observations
Ujjwal Upadhyay, Tarun Deep Saini, Shiv K. Sethi
The peculiar motions of galaxies are powerful cosmological probes that trace the growth of structures and the distribution of matter in the universe, providing a means to investiga…
