Constraining the Coexistence of Primordial Black Holes and Particle Dark Matter with Neutrino Observations
Prolay Chanda, Sagnik Mukherjee, James Unwin
The paper studies how high‑energy neutrino data can limit scenarios where primordial black holes coexist with particle dark matter, focusing on enhanced annihilation in dark‑matter…
Multipolar Dark Matter Freeze-out in an Early Matter-Dominated Universe
Debajit Bose, Prolay Chanda, Suvam Maharana +1
The relic abundance of thermal dark matter depends not only on its particle interactions but also on the expansion history of the early Universe. We study the freeze-out of fermion…
Profiling Dark Matter Spikes with Gravitational Waves from Accelerated Binaries
Avinash Tiwari, Prolay Chanda, Shasvath J. Kapadia +3
Dark matter halos can develop a density spike, e.g., around a galactic supermassive black hole, with the profile determined both by the galaxy's format…
Improved Constraints on Dark Matter Annihilations Around Primordial Black Holes
Prolay Chanda, Jakub Scholtz, James Unwin
Cosmology may give rise to appreciable populations of both particle dark matter and primordial black holes (PBH) with the combined mass density providing the observationally inferr…
