Probing Gauged Sub-GeV Dark Matter via Cosmic Ray Cooling in Active Galactic Nuclei
Arvind Kumar Mishra, Ning Liu, Chih-Ting Lu
Cosmic rays (CRs) traversing the dark matter (DM) spike surrounding active galactic nuclei (AGNs) can be cooled through interactions with DM particles. In this study, we investigat…

Neutron Star Collapse From Accretion: a Probe of Massive Dark Matter Particles
Ning Liu, Arvind Kumar Mishra
We explore the multi-scatter capturing of the massive dark matter (DM) particle inside the neutron star via a momentum-dependent dark matter-nucleon scattering cross-section. We fi…
