2011/10/17
In this paper we derive, directly from the Nambu-Goto action, the relevant components of the acceleration of cosmological featureless $p$-branes, extending previous analysis based on the field theory ...
Cosmological evolution of massive black holes: effects of Eddington ratio distribution and quasar lifetime
Galaxy Astrophysics (astro-ph.GA)
font style='font-size:12px;'>
2010/12/22
A power-law time-dependent lightcurve for active galactic nuclei (AGNs) is expected by the self-regulated black hole growth scenario, in which the feedback of AGNs expels gas and shut down accretion. ...

The latest determination of the extragalactic gamma-ray background (EGRB) radiation by Fermi is compared with the theoretical prediction of the blazar component by Inoue & Totani (2009; hereafter IT09...
