What is the Origin of the Baldwin Effect in the BLR and the NLR?
Alexei Baskin, Ari Laor
The origin of the luminosity dependence of the strength of broad and narrow emission lines in AGN (i.e. the Baldwin effect) is not firmly established yet. We explore this question…
Some Comments related to AGN Radio Loudness
Ari Laor
The bimodality of the AGN radio loudness distribution, and the relation of radio loudness and black hole mass were recently disputed. A closer look at the existing data suggests po…
What is the Broad Line Region?
Ari Laor
What is the Broad Line Region (BLR) made of? What determines its location? Why is it sometimes missing? What controls its properties? Some recent results and new approaches which m…
The Luminosity Dependence of UV Absorption in AGN
A. Laor, W. N. Brandt
We describe the results of a survey of the UV absorption properties of the Boroson & Green sample of AGN, which extends from the Seyfert (M_V ~ -21) to the luminous quasar (M_V ~ -…
BeppoSAX broad-band observations of low-redshift quasars: Spectral curvature and iron K_alpha lines
T. Mineo, F. Fiore, A. Laor +7
We present results from BeppoSAX observations of 10 low redshift quasars. The quasars are part of the Laor et al. (1997) sample of 23 optically selected PG quasars with redshift <0…
X-ray Absorption in Radio-Quiet QSOs
W. N. Brandt, S. C. Gallagher, A. Laor +1
Major flows of ionized gas are thought to be present in the nuclei of most luminous QSOs, and absorption by these flows often has a significant effect upon the observed X-ray conti…
