Reverberation Measurements for 17 Quasars and the Size-Mass-Luminosity Relations in Active Galactic Nuclei
TL;DR: In this article, the authors used spectro- photometrically monitored Palomar-Green quasars in order to obtain mea- surements of their emission lines and investigate the relationship between quasar luminosity, central black hole mass, and broad emission-line regions (BLRs) size in AGNs.
Journal ArticleDOI
Long-term optical variability properties of the Palomar–Green quasars
TL;DR: In this paper, the authors present results from a monitoring program of 42 quasars from the Palomar-Green sample, which was observed for seven years at the Wise Observatory, as part of a long-term effort to monitor AGN of various types.
Journal ArticleDOI
The excitation and metallicity of galactic HII regions from Infrared Space Observatory SWS observations of mid-infrared fine-structure lines
TL;DR: In this paper, the authors present mid-infrared Infrared Space Observatory Short-Wavelength Spectrometer (ISO-SWS) observations of the fine-structure emissions lines [Ne II] 12.8?m, [Ne III] 15.5?m and [Ar III] 8.99?m.
Journal ArticleDOI
Reverberation Measurements for 17 Quasars and the Size-Mass-Luminosity Relations in Active Galactic Nuclei
TL;DR: In this paper, the scaling relationship between the mass of the central black holes and the luminosity in active galactic nuclei (AGN) was investigated, and it was shown that the effective ionization parameter in AGN may be a decreasing function of luminosity.
Journal ArticleDOI

TL;DR: In this article, mid-infrared images of the Seyfert 1 galaxy Mrk 279 obtained with the ISO satellite are presented together with the results of a one-year monitoring campaign of the 2.5-11.7 mum spectrum.
