Relations between Massive Black Holes in AGN and their Host Galaxies
Amri Wandel
Massive black holes detected in the centers of many nearby galaxies are linearly correlated with the luminosity of the host bulge, the black hole mass being about 0.1% of the bulge…
The Black Hole-Host Galaxy Relation in Active Galactic Nuclei
Amri Wandel
The masses of the central black holes of Active Galactic Nuclei estimated by the reverberation virial technique seem to be significantly smaller than predicted from the black hole…
Evolutionary Baldwin Effect in AGN
Amri Wandel
Assuming Active Galactic Nuclei are powered by accretion onto a massive black holes we suggest that the growth of the central black hole due to the matter accreted over the AGN lif…
Spectral Dependence of the Broad Emission-Line Region in AGN
Amri Wandel
We derive a theoretical relation between , the size of the broad-emission-line region of active galactic nuclei, and the observed soft X-ray luminosity and spectrum. We sh…
The Mass-Luminosity Relation in AGN
Amri Wandel
Probably the most fundamental characteristic of the quasar-AGN power house, the mass of the central black hole, is the least well known. I review the three main classes of mass est…
BLR sizes and the X-ray spectrum in AGN
Amri Wandel, Thomas Boller
Recent ROSAT studies of narrow-line Seyfert 1 galaxies revealed these objects (with FWHM ) generally show steeper soft X-ray spectra than broad line Seyfert…
