The Existence of Sterile Neutrino Halos in Galactic Centers as an Explanation of the Black Hole mass - Velocity Dispersion Relation
M. H. Chan, M. -C. Chu
If sterile neutrinos exist and form halos in galactic centers, they can give rise to observational consequences. In particular, the sterile neutrinos decay radiatively and heat up…
A Predicted Relation between the Temperature and Density Profile of Cluster Hot Gas
M. H. Chan, M. C. Chu
Based on the assumptions that a fraction of cluster dark matter is composed of degenerate neutrinos and they are in hydrostatic equilibrium with other matter, we predict a relation…
Decaying Sterile Neutrinos as a Heating Source in the Milky Way Center
M. H. Chan, M. -C. Chu
Recent Chandra and Newton observations indicate that there are two-temperature components ( 8 keV, 0.8 keV) of the diffuse x-rays emitted from deep inside the center of Mil…
Formation of Neutrino Stars from Cosmological Background Neutrinos
M. H. Chan, M. -C. Chu
We study hydrodynamic evolution of cosmological background neutrinos. By using a spherically symmetric Newtonian hydrodynamic code, we calculate the time evolution of the density p…
Heating the intergalactic medium by radiative decay of neutrinos
M. H. Chan, M. -C. Chu
Assuming that there exists a species of heavy sterile neutrinos( keV) and their decays can serve as a heating source of the hot gas in galaxy clusters, we study how the obse…
Neutrino Star as Galactic Cluster Dark Halo
M. H. Chan, M. C. Chu
Recent Strong lensing data and rotation curves of dwarf galaxies indicate that many galactic clusters may have a soft core instead of a central cusp in their density distribution.…
