Particle dark matter searches in the anisotropic sky

Frontiers in Physics, 2014
Anisotropies in the electromagnetic emission produced by dark matter annihilation or decay in the extragalactic sky are a recent tool in the quest for a particle dark matter evidence.

Bouncing Dark Matter

, 2022
We present a novel mechanism for thermal dark matter production, characterized by a 'bounce': the dark matter equilibrium distribution transitions from the canonical exponentially falling abundance to an exponentially rising one, resulting in an ...

Searching for Dark Structures: A Comparison of Weak-lensing Convergence Maps and Lensing-weighted Galaxy Density Maps

The Astrophysical Journal Supplement Series
We present the result of a comparison between the dark matter distribution inferred from weak gravitational lensing and the observed galaxy distribution to identify dark structures with a high dark-matter-to-galaxy density ratio.

Dark matter in Sa galaxies: NGC 2179 and NGC 2775

, 1998
We present measurements of the stellar and ionized gas velocity curves and velocity dispersion profiles along the major axis for two Sa galaxies, NGC 2179 and NGC 2775. The luminosity profiles and the stellar kinematics of each galaxy are used to compute

Seven Hints for Primordial Black Hole Dark Matter [PDF]

, 2017
Seven observations point towards the existence of primordial black holes (PBH), constituting the whole or an important fraction of the dark matter in the Universe: the mass and spin of black holes detected by Advanced LIGO/VIRGO, the detection of micro ...

Time delay of light in the gravitational lensing of supermassive black holes in dark matter halos

European Physical Journal C: Particles and Fields
The dark matter halo has non-negligible effects on the gravitational lensing of supermassive black hole in the galaxy center. Our work presents a study on the time-delay of light in gravitational lensing of black holes enclosed by dark matter halos.

Galactic Dark Matter

, 2013
The precise phase-space distribution and properties of Galactic dark matter necessary for its direct and indirect detection are currently unknown. Since the distributions of normal and dark matter in the Milky Way are coupled to each other as they both ...

Modelling the IGM and the Ly alpha forest at high redshift from the dark matter distribution [PDF]

, 2002
A variety of approximate schemes for modelling the low-density intergalactic medium (IGM) in the high-redshift Universe are compared with the results of a large high-resolution hydrodynamical simulation. These schemes use either an analytical description
