Stronger Constraints on Primordial Black Holes as Dark Matter Derived from the Thermal Evolution of the Intergalactic Medium over the Last Twelve Billion Years

Nabendu Kumar Khan, Anupam Ray, Girish Kulkarni +1

Primordial black holes (PBHs) have been explored as potential dark matter candidates, with various astrophysical observations placing upper limits on the fraction …

Neutrinos from Earth-Bound Dark Matter Annihilation

Maxim Pospelov, Anupam Ray

A sub-component of dark matter with a short collision length compared to a planetary size leads to efficient accumulation of dark matter in astrophysical bodies. We analyze possibl…

Evolution of Tau-Neutrino Lepton Number in Protoneutron Stars due to Active-Sterile Neutrino Mixing

Anupam Ray, Yong-Zhong Qian

We present an approximate treatment of the mixing between () and a sterile species () with a vacuum mass-squared difference of 10-10 ke…

Dark Matter Annihilation inside Large Volume Neutrino Detectors

David McKeen, David E. Morrissey, Maxim Pospelov +2

New particles in theories beyond the standard model can manifest as stable relics that interact strongly with visible matter and make up a small fraction of the total dark matter a…

Can LIGO Detect Non-Annihilating Dark Matter?

Sulagna Bhattacharya, Basudeb Dasgupta, Ranjan Laha +1

Dark matter from the galactic halo can accumulate in neutron stars and transmute them into sub-2.5 black holes if the dark matter particles are heavy, stable, and have…

Celestial Objects as Strongly-Interacting Non-Annihilating Dark Matter Detectors

Anupam Ray

Non-annihilating dark matter particles, owing to their interactions with ordinary baryonic matter, can efficiently accumulate inside celestial objects. For heavy mass, they gravita…
