Sensitivity of the Global 21-cm Signal to Dark Matter-Baryon Scattering
Aryan Rahimieh, Priyank Parashari, Rui An +3
With current and upcoming experiments on the horizon, the global 21-cm signal can open up new avenues for probing dark matter (DM) physics at redshifts that are otherwise inaccessi…
Lyα forest bounds on sterile neutrino production via neutrino self-interactions
Priyank Parashari, Vera Gluscevic, Yue Zhang +3
Sterile neutrinos in the keV mass range have long been considered a well-motivated dark matter (DM) candidate. In this work, we explore a sterile neutrino production mechanism thro…
Hunting Primordial Black Hole Dark Matter in Lyman- Forest
Akash Kumar Saha, Abhijeet Singh, Priyank Parashari +1
A very pressing question in contemporary physics is the identity of Dark Matter (DM). Primordial Black Holes (PBHs) are one of the most well-motivated DM candidates. Light PBHs hav…
Probing the cosmic sterile-neutrino background with IceCube
Bhavesh Chauhan, Priyank Parashari
In this paper, we take a close look at the interaction between the TeV--PeV energy astrophysical neutrinos and a hypothetical cosmic sterile-neutrino background. These interactions…
Forecasting 21-cm power spectrum sensitivity to dark Matter-baryon scattering
Aryan Rahimieh, Priyank Parashari, Vera Gluscevic
We explore the potential of upcoming 21-cm interferometric observations to probe interacting dark matter (IDM). We focus on scenarios where the dark matter-baryon scattering cross-…
First Search for High-Energy Neutrino Emission from Galaxy Mergers
Subhadip Bouri, Priyank Parashari, Mousumi Das +1
The exact sources of high-energy neutrinos detected by the IceCube neutrino observatory still remain a mystery. For the first time, this work explores the hypothesis that galaxy me…
