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)…

Near future MeV telescopes can discover asteroid-mass primordial black hole dark matter
Anupam Ray, Ranjan Laha, Julian B. Muñoz +1
Primordial black holes (PBHs), formed out of large overdensities in the early Universe, are a viable dark matter (DM) candidate over a broad range of masses. Ultra-light, asteroid-…
