Dan Hooper on Light WIMPs
“The thermal abundance (“WIMP Miracle”) argument works roughly equally well for WIMPs with masses between ~1 GeV and several TeV, but historically, physicists have focused on ~40 GeV to ~1 TeV WIMPs, and papers have been written, analyses have been carried out, … Continue reading
Gustafsson in PPC-CERN: “Fermi Gamma-ray Space Telescope Observations of the Galactic Center”
A forthcoming paper of the Fermi-LAT Collaboration will describe method and results yielding to the left plot (the right one is widely known). A map of the galactic center after 2 years of Fermi operation by the Large Area Telescope (LAT) … Continue reading
Serpico at PPC-CERN: “Theoretical aspects of dark matter indirect detection”
“Dark Matter (DM) was already discovered indirectly: via gravity. But gravity is “universal” and does not permit particle identification: a discovery via electromagnetic, strong or weak probes is needed. The LHC at CERN was designed to study the electroweak (EW) scale, however there … Continue reading
Peebles in Nature, “How galaxies got their black holes”
“A large galaxy usually has a central, compact massive object, termed a relativistic black hole for want of a better idea of what it is, that can produce great bursts of energy. When the black hole is surrounded by a … Continue reading

Gianfranco Bertone, “The moment of truth for WIMP Dark Matter”
Gianfranco Bertone, “The moment of truth for WIMP Dark Matter,” ArXiv, Nov. 17, 2010 [Nature 468: 389–393, 18 November 2010], tell us everything we want to know about WIMP particles as candidates for dark matter. Let us summarize the paper. We know … Continue reading
