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

GeV-scale dark matter: production at the Main Injector
, 2014 Assuming that dark matter particles interact with quarks via a GeV-scale mediator, we study dark matter production in fixed target collisions. The ensuing signal in a neutrino near detector consists of neutral-current events with an energy distribution ...

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

Distribution of Dark Matter in Galaxies, In Search of the Dark Matter Particle
IOSR Journal of Applied Physics, 2014 A new theory called, the Dark Matter Flow Theory based on fluid mechanics concepts, has been given for the first time to derive the density of the dark matter and its distribution inside galaxies and beyond. Although the results are chocking, however they exhibit a high congruence with the measured observations of the velocity rotation curves of ...

The Impact of Dark Matter on Gravitational Wave Detection by Space-Based Interferometers
UniverseThe existence of dark matter is supported by multiple astrophysical observations, yet its particle nature remains unknown. The development of gravitational wave astronomy, especially with future space-based detectors such as LISA, provides new ...

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

The Distribution of Dark Matter in Spirals [PDF]
EAS Publications Series, 2006 In the past years a wealth of observations allowed to unravel the structural properties of the Dark Matter Halos around spirals. First, their rotation curves follow an Universal profile (URC) that can be described in terms of an exponential thin stellar disk and a dark halo with a constant density core, whose relative importance increases with galaxy ...

The Astrophysical JournalA fundamental prediction of the Lambda cold dark matter cosmology is the centrally divergent cuspy density profile of dark matter haloes. Density cusps render cold dark matter haloes resilient to tides, and protect dwarf galaxies embedded in them from ...

Dark Matter Structures in the Universe: Prospects for Optical Astronomy in the Next Decade
, 2009 The Cold Dark Matter theory of gravitationally-driven hierarchical structure formation has earned its status as a paradigm by explaining the distribution of matter over large spans of cosmic distance and time. However, its central tenet, that most of the
