Beyond the LCDM Universe: Some Alternative Models and Their Imprint on the Cosmic Microwave Background

This lecture explores alternative cosmological models beyond the Lambda Cold Dark Matter (LCDM) paradigm, presented by Tapomoy Guha Sarkar from the International Centre for Theoretical Sciences. Delve into theoretical frameworks that challenge the standard model of cosmology and examine how these alternatives leave distinctive imprints on observable phenomena. Part of the "Radio Cosmology and Continuum Observations in the SKA Era: A Synergic View" program, this talk connects to the broader context of preparing for the Square Kilometre Array (SKA) telescope's operations beginning in 2027. Learn about cutting-edge cosmological theories that may be tested with next-generation radio astronomy observations, offering insights for researchers interested in theoretical cosmology and observational tests of fundamental physics.
