Cosmic rays, lithium abundance and excess entropy in galaxy clusters
Biman B. Nath, Piero Madau, Joseph Silk
We consider the production of Li in spallation reactions by cosmic rays in order to explain the observed abundance in halo metal-poor stars. We show that heating of ambient gas…

Self-regulated black hole accretion, the M-sigma relation, and the growth of bulges in galaxies
Mitchell C. Begelman, Biman B. Nath
We argue that the velocity dispersions and masses of galactic bulges and spheroids are byproducts of the feedback that regulates rapid black hole growth in protogalaxies. We sugges…
