Constraining the neutral hydrogen (HI) distribution
Minal Chhabra, Raghunath Ghara, Somnath Bharadwaj
We constrain the HI distribution by jointly modeling two independent, existing observations of the 21-cm signal, the HI density parameter measured using…

Fuzzy Dark Matter Halo Mass Functions at Cosmic Dawn
Raghunath Ghara, Adam Lidz, Daniel Grin +1
In fuzzy dark matter (FDM) cosmological models, wave effects impact astrophysical length scales, suppressing the abundance of small mass dark matter halos, and delaying the earlies…

POLAR-II: modeling star formation history of galaxies on the 21-cm signal from Epoch of Reionization
Qing-Bo Ma, Raghunath Ghara, Benedetta Ciardi +6
Galaxies may suffer some starburst and quenched periods in their history due to e.g. galaxy mergers and feedback. However, semi-numerical simulations of the Epoch of Reionization (…
