MC2: CONSTRAINING THE DARK MATTER DISTRIBUTION OF THE VIOLENT MERGING GALAXY CLUSTER CIZA J2242.8+5301 BY PIERCING THROUGH THE MILKY WAY [PDF]
, 2014 The galaxy cluster CIZA J2242.8+5301 at z = 0.19 is a merging system with a prominent (∼2 Mpc long) radio relic, which together with the morphology of the X-ray emission provides strong evidence for a violent collision along the north–south axis.

Axion quark nugget dark matter model: Size distribution and survival pattern [PDF]
Physical Review D, 2019 We consider the formation and evolution of Axion Quark Nugget dark matter particles in the early universe. The goal of this work is to estimate the mass distribution of these objects and assess their ability to form and survive to the present day.

Dark Matter direct detection of classical WIMPs
SciPost Physics Lecture Notes, 2022 One of the highest priorities in particle physics today is the identification of the constituents of dark matter. This manuscript is a supplement to pedagogical lectures given at the 2021 Les Houches Summer School on Dark Matter.

Under the FIRElight: Stellar Tracers of the Local Dark Matter Velocity Distribution in the Milky Way [PDF]
Astrophysical Journal, 2018 The Gaia era opens new possibilities for discovering the remnants of disrupted satellite galaxies in the solar neighborhood. If the population of local accreted stars is correlated with the dark matter sourced by the same mergers, one can then map the ...

The distribution of dark matter in galaxies [PDF]
The Astronomy and Astrophysics Review, 2018 The distribution of the non-luminous matter in galaxies of different luminosity and Hubble type is much more than a proof of the existence of dark particles governing the structures of the Universe.

Indirect Evidence for Dark Matter Density Spikes around Stellar-mass Black Holes
The Astrophysical Journal Letters, 2023 It has been suggested for a long time that dark matter would form a density spike around a black hole. However, no promising evidence has been observed so far to verify this theoretical suggestion.

Anisotropic dark matter distribution functions and impact on WIMP direct detection [PDF]
, 2013 Dark matter N-body simulations suggest that the velocity distribution of dark matter is anisotropic. In this work we employ a mass model for the Milky Way whose parameters are determined from a fit to kinematical data.

Impact of relativistic corrections on the detectability of dark-matter spikes with gravitational waves [PDF]
Physical Review D, 2022 Black holes located within a dark matter cloud can create overdensity regions known as dark matter spikes. The presence of spikes modifies the gravitational-wave signals from binary systems through changes in the gravitational potential or dynamical ...

Unified Dark Matter models with fast transition [PDF]
, 2010 We investigate the general properties of Unified Dark Matter (UDM) fluid models where the pressure and the energy density are linked by a barotropic equation of state (EoS) p = p(ρ) and the perturbations are adiabatic.
