Dark matter in compact stars

J Bramante, N Raj - Physics Reports, 2024 - Elsevier
WDs 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 black hole …

Bosonic dark matter in neutron stars and its effect on gravitational wave signal

D Rafiei Karkevandi, S Shakeri, V Sagun, O Ivanytskyi - Physical Review D, 2022 - APS
We study an impact of self-interacting bosonic dark matter (DM) on various observable
properties of neutron stars (NSs). The analysis is performed for asymmetric DM with masses …

Closing the window on WIMP Dark Matter

S Bottaro, D Buttazzo, M Costa, R Franceschini… - The European Physical …, 2022 - Springer
We study scenarios where Dark Matter is a weakly interacting particle (WIMP) embedded in
an ElectroWeak multiplet. In particular, we consider real SU (2) representations with zero …

Faint light of old neutron stars and detectability at the James Webb Space Telescope

S Chatterjee, R Garani, RK Jain, B Kanodia… - Physical Review D, 2023 - APS
Isolated ideal neutron stars (NS) of age> 10 9 yr exhaust thermal and rotational energies
and cool down to temperatures below O (100) K. Accretion of particle dark matter (DM) by …

Exoplanets as sub-GeV dark matter detectors

RK Leane, J Smirnov - Physical Review Letters, 2021 - APS
We present exoplanets as new targets to discover dark matter (DM). Throughout the Milky
Way, DM can scatter, become captured, deposit annihilation energy, and increase the heat …

Astroparticle physics with compact objects

P Tinyakov, M Pshirkov, S Popov - Universe, 2021 - mdpi.com
Probing the existence of hypothetical particles beyond the Standard model often deals with
extreme parameters: large energies, tiny cross-sections, large time scales, etc. Sometimes …

Bounds on long-lived dark matter mediators from neutron stars

TTQ Nguyen, TMP Tait - Physical Review D, 2023 - APS
Neutron stars close to the Galactic center are expected to swim in a dense background of
dark matter. For models in which the dark matter has efficient interactions with neutrons, they …

Celestial-body focused dark matter annihilation throughout the galaxy

RK Leane, T Linden, P Mukhopadhyay, N Toro - Physical Review D, 2021 - APS
Indirect detection experiments typically measure the flux of annihilating dark matter (DM)
particles propagating freely through galactic halos. We consider a new scenario where …

The last complex WIMPs standing

S Bottaro, D Buttazzo, M Costa, R Franceschini… - The European Physical …, 2022 - Springer
We continue the study of weakly interacting massive particles (WIMP) started in Bottaro et
al.(Eur Phys JC 82: 31, 2022), focusing on a single complex electroweak n-plet with non …

Floating dark matter in celestial bodies

RK Leane, J Smirnov - Journal of Cosmology and Astroparticle …, 2023 - iopscience.iop.org
Dark matter (DM) can be captured in celestial bodies after scattering and losing sufficient
energy to become gravitationally bound. We derive a general framework that describes the …
