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…
