Background of radio photons from primordial black holes
Shikhar Mittal, Girish Kulkarni
We compute the isotropic radiation background due to Hawking emission from primordial black holes (PBHs), and examine if this background is a viable option in explaining the excess…

Constraining primordial black holes as dark matter using the global 21-cm signal with X-ray heating and excess radio background
Shikhar Mittal, Anupam Ray, Girish Kulkarni +1
Using the global 21-cm signal measurement by the EDGES collaboration, we derive constraints on the fraction of the dark matter that is in the form of primordial black holes (PBHs)…
