Does the High Energy LUX-ZEPLIN Event Suggest Hyperfine Atomic Dark Matter?
Prolay Chanda, Bhaskar Das, Sagnik Mukherjee
The LUX-ZEPLIN (LZ) Collaboration has reported a nuclear-recoil candidate at in an extended high energy search window. We investi…
Constraining the Coexistence of Primordial Black Holes and Particle Dark Matter with Neutrino Observations
Prolay Chanda, Sagnik Mukherjee, James Unwin
Primordial black holes (PBH) with a uniform mass scale could contribute up to 1\% of the gravitationally inferred dark matter relic abundance and remain consistent with observation…
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 formatio…
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…
Decoupling of Asymmetric Dark Matter During an Early Matter Dominated Era
Prolay Chanda, James Unwin
In models of Asymmetric Dark Matter (ADM) the relic density is set by a particle asymmetry in an analogous manner to the baryons. Here we explore the scenario in which ADM decouple…
Reviving and Higgs Mediated Dark Matter Models in Matter Dominated Freeze-out
Prolay Chanda, Saleh Hamdan, James Unwin
It is quite conceivable that dark matter freeze-out occurred during an early period of matter domination, in which case the evolution and relic abundance differ from standard freez…
