Dark matter, black holes, and gravitational waves [PDF]
Nuclear Physics BThe formation and growth of black holes can strongly influence the distribution of dark matter around them. I discuss here the different types of dark matter overdensities around black holes, including dark matter cusps, spikes, mounds, crests, and ...

Spatial Distribution of Intracluster Light versus Dark Matter in Horizon Run 5 [PDF]
The Astrophysical JournalOne intriguing approach for studying the dynamical evolution of galaxy clusters is to compare the spatial distributions among various components such as dark matter, member galaxies, gas, and intracluster light (ICL).

Limits on spin-dependent WIMP-proton cross-sections using the DRIFT-IId directional dark matter detector [PDF]
, 2011 The nature of dark matter remains one of the biggest questions in physics today. Weakly Interacting Massive Particles (WIMPs) are a particularly well motivated candidate for the missing matter that makes up 85% of the mass of the Universe.

Effects on the local dark matter distribution due to the Large Magellanic Cloud [PDF]
, 2021 We study the local dark matter distribution in two models for the Milky Way (MW)-Large Magellanic Cloud (LMC) interaction. The effect of the LMC on the local dark matter distribution is dependent on the evolution of the MW-LMC system, such that a static ...

Revisiting dark matter freeze-in and freeze-out through phase-space distribution [PDF]
Journal of Cosmology and Astroparticle Physics, 2021 We revisit dark-matter production through freeze-in and freeze-out by solving the Boltzmann equations at the level of the phase-space distribution f(p,t).

Dependence of dark matter - electron scattering on the galactic dark matter velocity distribution [PDF]
Journal of Cosmology and Astroparticle Physics, 2020 The rate of dark matter-electron scattering depends on the underlying velocity distribution of the dark matter halo. Importantly, dark matter-electron scattering is particularly sensitive to the high-velocity tail, which differs significantly amongst the

Dark matter spike around Bumblebee black holes [PDF]
Journal of Cosmology and Astroparticle Physics, 2023 The effects of dark matter spike in the vicinity of the supermassive black hole, located at the center of M87 (the Virgo A galaxy), are investigated within the framework of the so-called Bumblebee Gravity.
