Bounds on abundance of primordial black hole and dark matter from EDGES 21-cm signal
Ashadul Halder, Shibaji Banerjee
The redshifted 21cm radio signal has emerged as an important probe for investigating the dynamics of the dark age Universe (recombination to reionization). In the current analysis,…

Probing the effects of primordial black holes on 21-cm EDGES signal along with interacting dark energy and dark matter - baryon scattering
Ashadul Halder, Madhurima Pandey
21-cm radio signal has emerged as an important probe in investigating the dark age of the Universe (recombination to reionization). In the current analysis, we explore the combined…
