Next-to-Minimal Freeze-in Dark Matter
Nicolás Bernal, Sagnik Mukherjee, James Unwin
If the dark matter mass exceeds the highest temperature of the thermal bath, then dark matter production is Boltzmann suppressed. This opens new possibilities for dark matter model…

Constraining the Coexistence of Freeze-in Dark Matter and Primordial Black Holes
Prolay Chanda, Sagnik Mukherjee, James Unwin
Particle dark matter and primordial black holes (PBH) might coexist with appreciable cosmic abundances, with both contributing to the observed dark matter density . Lar…
