WebGlobular clusters are the only known stellar population that formed in essentially direct proportion to host galaxy halo mass. The intrinsic scatter in η 𝜂 \eta italic_η appears to be at most 0.2 dex; we argue that some of this scatter is due to differing degrees of tidal stripping of the globular cluster systems between central and satellite galaxies.

WebThe STUMP scenario for dark matter, based on the physics of neutron stars, proposes that dark matter is an ultralight fermion charged to the standard model baryon number. Near-constant density cores in dark matter halos are predicted by this model, which begins with a flaw in the Tremaine-Gunn bound on fermionic dark matter. WebBecause of the high density achieved at caustics, the dark matter annihilation rate is expected to be enhanced relative to the smooth dark matter halo contribution. This … methodology waterfall modelAccording to modern models of physical cosmology, a dark matter halo is a basic unit of cosmological structure. It is a hypothetical region that has decoupled from cosmic expansion and contains gravitationally bound matter.
