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…
Dissipative Dark Energy can explain the DESI phantom crossing
Prolay Chanda, Subinoy Das, Suratna Das
DESI results preferring an evolving dark energy component that appears to cross the phantom-divide in the recent past has raised a lot of interest in exploring the nature of dark e…
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…
DESI results: Hint towards coupled dark matter and dark energy
Amlan Chakraborty, Prolay K. Chanda, Subinoy Das +1
We investigate a scenario where a dark energy quintessence field with positive kinetic energy is coupled with dark matter. With two different self-interaction potentials for th…
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…
Formation and Abundance of Late Forming Primordial Black Holes as Dark Matter
Amlan Chakraborty, Prolay K Chanda, Kanhaiya Lal Pandey +1
We propose a novel mechanism where Primordial Black Hole (PBH) dark matter is formed much later in the history of the universe between the epoch of Big Bang Nucleosynthesis (BBN) a…
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…
Early mass varying neutrino dark energy: Nugget formation and Hubble anomaly
Antareep Gogoi, Ravi Kumar Sharma, Prolay Chanda +1
We present a novel scenario, in which light ( few \rm{eV}) dark fermions (sterile neutrinos) interact with a scalar field like in mass varying neutrino dark energy theories.…
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…
Static structure of chameleon dark Matter as an explanation of dwarf spheroidal galactic core
Prolay Krishna Chanda, Subinoy Das
We propose a novel mechanism which explains cored dark matter density profile in recently observed dark matter rich dwarf spheroidal galaxies. In our scenario, dark matter particle…
