Non-baryonic, or "dark", matter is believed to be a major component of the total mass budget of the Universe. We review the candidates for particle dark matter and discuss the prospects for direct detection (via interaction of dark matter particles with laboratory detectors) and indirect detection (via observations of the products of dark matter self-annihilations), focusing in particular on the Galactic center, which is among the most promising targets for indirect detection studies. The…

Strategies for Determining the Nature of Dark Matter
In this review, we discuss the role of the various experimental programs taking part in the effort to identify the particle nature of dark matter. In particular, we focus on electroweak-scale dark…
Search for dark matter annihilation in the Galactic Center with IceCube-79
The Milky Way is expected to be embedded in a halo of dark matter particles, with the highest density in the central region, and decreasing density with the halo-centric radius. Dark matter might be…

Dark Matter distribution in the Milky Way: microlensing and dynamical constraints
We show that current microlensing and dynamical observations of the Galaxy permit to set interesting constraints on the Dark Matter local density and profile slope towards the galactic centre.…
Dark matter annihilation around intermediate mass black holes: an update
The formation and evolution of black holes (BHs) inevitably affects the distribution of dark and baryonic matter in the neighborhood of the BH. These effects may be particularly relevant around…
Impact of astrophysical processes on the gamma-ray background from dark matter annihilations
We study the impact of astrophysical processes on the gamma-ray background produced by the annihilation of dark matter particles in cosmological halos, with particular attention to the consequences…
Angular signatures of dark matter in the diffuse gamma ray background
Dark matter annihilating in our galaxy’s halo and elsewhere in the universe is expected to generate a diffuse flux of gamma rays, potentially observable with next generation satellite-based…
Unidentified Fermi Objects in the view of H.E.S.S. - Possible Dark Matter Clumps
There is strong evidence about the existence of unknown dark matter in the Universe. Many different theories about this dark matter exist, but most probably it is made of a new kind of fundamental…
Indirect Detection of Dark Matter Using MeV-Range Gamma-Ray Telescopes
The astrophysics community is considering plans for a variety of gamma-ray telescopes (including ACT, GRIPS, and AdEPT) in the energy range 1--100 MeV, which can fill in the so-called ``MeV gap'' in…
Consequences of dark matter self-annihilation for galaxy formation
Galaxy formation requires a process that continually heats gas and quenches star formation in order to reproduce the observed shape of the luminosity function of bright galaxies. To accomplish this,…

Non-baryonic dark matter: observational evidence and detection methods
The evidence for the existence of dark matter in the universe is reviewed. A general picture emerges, where both baryonic and non-baryonic dark matter is needed to explain current observations. In…
Astrophysical Limits on Massive Dark Matter
Annihilations of weakly interacting dark matter particles provide an important signature for the possibility of indirect detection of dark matter in galaxy halos. These self-annihilations can be…
Dark matter annihilation in the local group
Under the hypothesis of a Dark Matter composed by supersymmetric particles like neutralinos, we investigate the possibility that their annihilation in the haloes of nearby galaxies could produce…
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…
Evolution of the dark matter distribution at the galactic center.
TLDR
Here the time-dependent equations describing gravitational interaction of the dark matter with the stars are solved and imply a decrease by several orders of magnitude in the observable flux of annihilation products compared with models that associate a steep, dark matter spike with the SBH.
Dark matter annihilation in the milky way galaxy: effects of baryonic compression.
TLDR
It is argued that the most important effect, which was previously neglected, is the compression of the dark matter due to the infall of baryons to the galactic center: it boosts the expected signal by a factor 1000.
Neutrinos from dark matter annihilations at the Galactic Center
We discuss the prospects for detection of high energy neutrinos from dark matter annihilation at the Galactic centre. Despite the large uncertainties associated with our poor knowledge of the…

TLDR
It is shown that a 1-km2 area is the natural scale of a neutrino telescope capable of probing the GeV-TeV neutralino mass range by searching for high-energy neutrinos produced by their annihilation in the Sun.
