On the dark matter distribution in the Milky Way
, 2016 The distribution of dark matter in the Milky Way is a crucial input for ongoing studies in cosmology, astrophysics and particle physics. This motivates the effort over the next years to improve our mapping of dark matter, which has indeed become a top ...

Evolution of the Dark Matter Distribution at the Galactic Center
Physical Review Letters, 2004 Annihilation radiation from neutralino dark matter at the Galactic center (GC) would be greatly enhanced if the dark matter were strongly clustered around the supermassive black hole (SBH). The existence of a dark-matter "spike" is made plausible by the observed, steeply-rising stellar density near the GC SBH.

, 2018 Past studies have identified a spatially extended excess of ~1-3 GeV gamma rays from the region surrounding the Galactic Center, consistent with the emission expected from annihilating dark matter. We revisit and scrutinize this signal with the intention

A superfluid dark matter cosmic string wake
European Physical Journal C: Particles and FieldsWe study the effects of superfluid dark matter on the structure of a cosmic string wake, considering both the effects of regular and quantum pressure terms. We consider the total fluid to consist of a combination of baryons and dark matter. Hence, we are

Emergent dark matter in late time universe on holographic screen
Journal of High Energy Physics, 2018 We discuss a scenario that the dark matter in late time universe emerges as part of the holographic stress-energy tensor on the hypersurface in higher dimensional flat spacetime.

Constraining Dark Matter properties with the Inter-Galactic Medium and other probes [PDF]
, 2019 According to the standard cosmological (ΛCDM) model, the universe today is mainly composed by a cosmological constant, denoted by Λ, and by Cold Dark Matter (CDM). Whereas this standard paradigm is tremendous agreement with Cosmic Microwave Background

Chinese Physics CAbstract The recently discovered satellite dwarf galaxy Ursa Major III provides a promising opportunity to explore the signatures resulting from dark matter (DM) annihilation owing to its proximity and large J-factor. Given the absence of an excess of γ-ray signatures originating from Ursa Major III, observations of γ-rays, such as those

Polarized equatorial emission and hot spots around black holes with a dark matter halo
European Physical Journal C: Particles and FieldsWe study linear polarization of the accretion disks around black holes with a dark matter halo. The interaction of the black hole with the dark matter is modeled by considering an exact solution to the Einstein equations which describe a superposition of

A NEW POPULATION OF WIMPS IN THE SOLAR SYSTEM AND INDIRECT DETECTION RATES
, 2001 A new Solar System population of Weakly Interacting Massive Particle (WIMP) dark matter has been proposed to exist. We investigate the implications of this population on indirect signals in neutrino telescopes (due to WIMP annihilations in the Earth) for

Dark Matter Distribution in Milky Way analog Galaxies
The Astrophysical JournalOur current understanding of how dark matter (DM) is distributed within the Milky Way (MW) halo, particularly in the solar neighborhood, is based on either careful studies of the local stellar orbits, model assumptions on the global shape of the MW halo,
