The energy budget for X-ray to infrared reprocessing in Compton-thin and Compton-thick active galaxies
The energy budget X-ray Compton-thin
2011/1/13
Heavily obscured active galactic nuclei (AGNs) play an important role in contributing to the cosmic X-ray background (CXRB). However, the AGNs found in deep X-ray surveys are often too weak to allow d...
High-resolution mapping of the physical conditions in two nearby active galaxies based on 12CO(1-0), (2-1) and (3-2) lines
Galaxy Astrophysics (astro-ph.GA)
2010/12/29
We present a detailed analysis of high resolution observations of the three lowest CO transitions in two nearby active galaxies, NGC4569 and NGC4826. The CO(1-0) and (2-1) lines were observed with the...

QSO Pairs across Active Galaxies: Evidence of Blueshifts?
Quasars: emission lines quasars: absorption lines cosmology: miscellaneous

Several QSO pairs have been reported and their redshifts determined, where the two objects in each pair are located across an active galaxy. The usually accepted explanation of such occurrences is tha...

Influence of the Black Hole Rotation on Accretion Discs and Jets in Active Galaxies: the Case of NGC 1068
the Black Hole Rotation Accretion Discs and Jets Active Galaxies the Case of NGC 1068
2010/10/18
Although we do not observe directly black holes in the Universe, their presence has been inferred in several astrophysical systems, from galactic to extragalactic scales. In this work, we will restric...
