Status, Challenges and Directions in Indirect Dark Matter Searches
In this review, the current status of indirect searches for dark matter is summarized, mentioning also the challenges and limitations that these techniques encounter.
Fermi-LAT prospects for the detection of μνSSM gravitino Dark Matter
The μνSSM is a supersymmetric model that has been proposed to solve the problems generated by other supersymmetric extensions of the standard model of particle physics. Given that R-parity is broken
CLUES on Fermi-LAT prospects for the extragalactic detection of μνSSM gravitino dark matter
Abstract The μ ν SSM is a supersymmetric model that has been proposed to solve the problems generated by other supersymmetric extensions of the standard model of particle physics. Given that R-parity
Axion decay and anisotropy of near-IR extragalactic background light
The extragalactic background light (EBL) is comprised of the cumulative radiation from all galaxies and active galactic nuclei over the cosmic history. In addition to point sources, EBL also contains
An Approach to Solution of the Dark Energy Problem
The recent observations of distant supernovae and CMB fluctuations increasingly imply that a dark energy in the universe is real and its present energy density (Ω Λ , 0) exceeds that of all other
Extragalactic background light: inventory of light throughout the cosmic history
ABSTRACT The Extragalactic Background Light (EBL) stands for the mean surface brightness of the sky as we would see it from a representative vantage point in the intergalactic space outside of our
Testing the Bose-Einstein Condensate dark matter model at galactic cluster scale
The possibility that dark matter may be in the form of a Bose-Einstein Condensate (BEC) has been extensively explored at galactic scale. In particular, good fits for the galactic rotations curves
Gamma-rays from decaying dark matter
We study the prospects for detecting gamma-rays from decaying dark matter (DM), focusing in particular on gravitino DM in R-parity breaking vacua. Given the substantially different angular
Mass-radius relation of Newtonian self-gravitating Bose-Einstein condensates with short-range interactions: II. Numerical results
Several recent astrophysical observations of distant type Ia supernovae have revealed that the content of the universe is made of about 70% of dark energy, 25% of dark matter and 5% of baryonic
Gravitational, lensing and stability properties of Bose-Einstein condensate dark matter halos
The possibility that dark matter, whose existence is inferred from the study of the galactic rotation curves, and from the mass deficit in galaxy clusters, can be in a form of a Bose-Einstein


Background Radiation Constraints on Supersymmetric Weakly Interacting Particles
Dark matter particles that annihilate each other or decay with long lifetimes can be constrained by data in various wavebands. Here we apply this method to supersymmetric weakly interacting massive
Detection of Leptonic Dark Matter
Weakly interacting massive particles (WIMPs) are among the favored candidates for cold dark matter in the universe. The phenomenology of supersymmetric WIMPs has been quite developed during recent
New Light on Dark Matter
How studies of the density, demography, history, and environment of smaller-scale structures may distinguish among these possibilities and shed new light on the nature of dark matter is discussed.
Cosmic microwave background constraints on a baryonic dark matter-dominated universe
In recent years, upper limits on the cosmic microwave background (CMB) anisotropies, combined with predictions made by theories of galaxy formation, have been extremely powerful in ruling out purely
Detectability of γ-rays from clumps of dark matter
IF the dark matter in our Galaxy is made up of weakly interacting massive particles (WIMPs) with masses of the order of several GeV (for example, photinos or Higgsinos), γ-rays produced by their
Constraints on decaying neutrinos from the far-ultraviolet extragalactic background light
We consider light neutrinos as dark matter candidates, concentrating on those proposed by Sciama, with rest energies near 30 eV and decay lifetimes of (2 +/- 1) x 10 exp 23 s. Using equations
Dark matter annihilation in the halo of the Milky Way
If the dark matter in the Universe is made of weakly self-interacting particles, they may self-annihilate and emit γ-rays. We use high-resolution numerical simulations to estimate directly the
Problems of modern cosmology: how dominant is the vacuum?
The review of evidence for and against the mysterious dark matter consists of as many as four separate ingredients: baryons, massive neutrinos, new "exotic" dark matter particles, and vacuum energy concludes by exploring the possibility that the energy density of the vacuum is in fact so dominant as to leave little room for significant amounts of exotic dark matter.
