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

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
