Dark matter scattering with pre-supernova neutrinos
Sangeetha N. Tallur, Nirmal Raj
Pre-supernova neutrinos, emitted during the last day prior to core collapse of a massive star, could provide a unique probe at MeV energies of scattering interactions between dark…
Dark, deep, deconfining: Phase transitions in neutron stars as powerful probes of hidden sectors
Aryaman Bhutani, Nirmal Raj, Zenia Zuraiq
The interiors of neutron stars enjoy ideal conditions for the conversion of hadrons to a strange quark phase, theorized to be the stablest form of matter. Though numerous astrophys…
Hawking heating of neutron stars by dark matter
Akash Kumar Saha, Abhishek Dubey, Nirmal Raj
Interactions with particle dark matter could brighten old, isolated neutron stars to thermal luminosities detectable at current and next-generation telescopes. We present a novel m…
Seeking the nearest neutron stars using a new local electron density map
Joseph Bramante, Katherine Mack, Nirmal Raj +2
Neutron stars provide a compelling testing ground for gravity, nuclear dynamics, and physics beyond the Standard Model, and so it will be useful to locate the neutron stars nearest…
limits from Super-Kamiokande on dark matter-electron scattering in the Sun
Dhashin Krishna, Rinchen Sherpa, Akash Kumar Saha +3
Particle dark matter scattering on electrons in the Sun may gravitationally capture and self-annihilate inside it to neutrinos and anti-neutrinos, or other final states that in tur…
Dark matter in compact stars
Joseph Bramante, Nirmal Raj
White dwarfs and neutron stars are far-reaching and multi-faceted laboratories in the hunt for dark matter. We review detection prospects of wave-like, particulate, macroscopic and…
