Dark matter halo concentrations: a short review
Chiamaka Okoli
This review analyzes the state and advancement of the dark matter halo concentrations over the last two decades. It begins with presenting the article that brought the field to the…
Searching for dark matter annihilation from individual halos: uncertainties, scatter and signal-to-noise ratios
Chiamaka Okoli, James E. Taylor, Niayesh Afshordi
Individual extragalactic dark matter halos, such as those associated with nearby galaxies and galaxy clusters, are promising targets for searches for gamma-rays from dark matter an…
Dynamical friction in the primordial neutrino sea
Chiamaka Okoli, Morag I. Scrimgeour, Niayesh Afshordi +1
Standard big bang cosmology predicts a cosmic neutrino background at K. Given the current neutrino oscillation measurements, we know most neutrinos move at large,…
Concentration, Ellipsoidal Collapse, and the Densest Dark Matter haloes
Chiamaka Okoli, Niayesh Afshordi
The smallest dark matter haloes are the first objects to form in the hierarchical structure formation of cold dark matter (CDM) cosmology and are expected to be the densest and mos…
