Using Artificial Neural Networks to extract the 21-cm Global Signal from the EDGES data
Madhurima Choudhury, Atrideb Chatterjee, Abhirup Datta +1
The redshifted 21-cm signal of neutral Hydrogen is a promising probe into the period of evolution of our Universe when the first stars were formed (Cosmic Dawn), to the period wher…
A hint on the metal-free star formation rate density from 21cm-EDGES data
Atrideb Chatterjee, Pratika Dayal, Tirthankar Roy Choudhury +1
We aim to provide the first data-constrained estimate of the metal-free (Population III; Pop III) star formation rate density required at high-redshifts ($z \gtrs…
Ruling out 3 keV warm dark matter using 21 cm-EDGES data
Atrideb Chatterjee, Pratika Dayal, Tirthankar Roy Choudhury +1
Weakly interacting cold dark matter (CDM) particles, which are otherwise extremely successful in explaining various cosmological observations, exhibit a number of problems on small…
