Particle dark matter searches in the anisotropic sky
*Correspondence: Nicolao Fornengo, Dipartimento di Fisica, Università di Torino and Istituto Nazionale di Fisica Nucleare, Via P. Giuria 1, Torino 10125, Italy e-mail: [email protected] Anisotropies in the electromagnetic emission produced by dark matter (DM) annihilation or decay in the extragalactic sky are a recent tool in the quest for a particle DM evidence. We review the formalism to co...
متن کاملDark Matter Signatures in the Anisotropic Radio Sky
We calculate intensity and angular power spectrum of the cosmological background of synchrotron emission from cold dark matter annihilations into electron positron pairs. We compare this background with intensity and anisotropy of astrophysical and cosmological radio backgrounds, such as from normal galaxies, radiogalaxies, galaxy cluster accretion shocks, the cosmic microwave background and wi...
متن کاملDark Matter Searches
I'll start with a summary of the relevant evidence for cold dark matter from astrophysics and cosmology. The Standard Model of subnuclear physics does not have any dark matter particle, but its simplest extensions, the SUSY models, do have a very apt candidate, the neutralino. I will then briefly summarise the status and the expectations for the next years of indirect searches both with earth-b...
متن کاملSearch for Dark Matter in the Sky
Can we learn about New Physics with astronomical and astro-particle data? Since its launch in 2008, the Large Area Telescope, onboard of the Fermi Gamma-ray Space Telescope, has detected the largest amount of gamma rays in the 20MeV 300GeV energy range and electrons + positrons in the 7 GeV1 TeV range. These impressive statistics allow one to perform a very sensitive indirect experimental searc...
متن کاملDirect searches for dark matter
In the last decade considerable additional evidence has been gathered supporting the hypothesis that at least 90% of the mass in the universe is dark: it does not emit or absorb any form of electromagnetic radiation. Understanding this dark matter has become one of the more central problems in astronomy and cosmology. Once a subject of controversy among astronomers, its existence is now well es...
