387. Mapping the baryonic Universe: a new window into the cosmos (Invited Talk)

Hamsa Padmanabhan

06/12/2023, 14:15

Mapping the baryonic content of the Universe, especially after the epoch of Cosmic Dawn -- the birth of the first stars and galaxies --- promises rich insights into both astrophysics and cosmology. The technique of intensity mapping (IM) has emerged as a powerful tool to explore this phase of the Universe by measuring the integrated emission from sources over a broad range of frequencies. A...

Universe has several poorly constrained periods over its evolution. Formation of first stars and galaxies, followed by reionization of the intergalactic medium is one such epoch. Often referred to as "cosmic dawn", observing this period is extremely challenging due to the faint nature of the signals originating from it. The redshifted 21-cm line from neutral hydrogen offers one such...
