A survey for large image-separation lensed quasars
Dan Maoz, Hans-Walter Rix, Avishay Gal-Yam +1
The statistics of gravitationally lensed quasars with multiple images in the 0.1''-7'' range have been measured in various surveys. Little is known, however, about lensed-quasar st…
Evidence for a New Class of Extreme UV Sources
Dan Maoz, Eran Ofek, Amotz Shemi
Most of the sources detected in the extreme ultraviolet (EUV; 100 Ang to 600 Ang) by the Rosat WFC and EUVE all-sky surveys have been identified with active late-type stars and hot…
Reverberation Mapping and Broad-Line Region Models
Dan Maoz
I review what we have learned about the BLR from reverberation mapping, point to some problems and complications that have emerged, and outline some future directions.
Measurement of the Broad Line Region Size in Two Bright Quasars
Shai Kaspi, Paul S. Smith, Dan Maoz +2
We present 4 years of spectrophotometric monitoring data for two radio-quiet quasars, PG 0804+762 and PG 0953+414, with typical sampling intervals of several months. Both sources s…
An Atlas of Hubble Space Telescope Ultraviolet Images of Nearby Galaxies
Dan Maoz, Alexei V. Filippenko, Luis C. Ho +3
We present an atlas of UV ( Å) images, obtained with the Hubble Space Telescope (HST) Faint Object Camera, of the central of 110 galaxies. The observed…
Multiwavelength observations of short time-scale variability in NGC 4151. IV. Analysis of multiwavelength continuum variability
R. A. Edelson et al
This paper combines data from the three preceding papers in order to analyze the multi-waveband variability and spectral energy distribution of the Seyfert~1 galaxy NGC~4151 during…
