Astronomy and Astrophysics
Saurabh's research focuses on experimental cosmology. He designs experiments to understand crucial epochs of the Universe via 21-cm intensity mapping. These periods include cosmic dawn, the epoch of reionization, and the era of dark energy domination. Such observations necessitate designing radio telescopes with extreme precision and accuracy. He is also interested in calibration strategies for radio telescopes, foreground modeling, cross-correlation with other observables, and statistical techniques to derive cosmological constraints from the observed data.
