Annapolis, Maryland Joe Silk, "DM Annihilations as a Probe of CDM Substructure"
- Proposing to use the Sun as a WIMP detector above 4 GeV (less massive ones are evaporated).
- If WIMPs are low-mass (5-10 GeV) and trapped, they will lower the central temperature of the Sun.
- Energetic neutrinos from WIMPs trapped in the Sun? Detectable by AMANDA or IceCube?
- Sommerfeld effect: boosting … Continue Reading ››
Annapolis, Maryland – Today's talks focus on dwarf galaxy formation Volker Bromm (UT-Austin), "The First Stars and Galaxies"
- Discussed Clark+ (2010), Greif+ (2011) simulations, looking at disk fragmentation in the case without radiation feedback. Points to a flat IMF.
- Stacy+ (2011) included proto-stellar radiative feedback and found that the final mass was 30-40 Msun in a binary. Hosogawa+ … Continue Reading ››
