Reverberation Mapping of High-Redshift, High-Luminosity Quasars
Shai Kaspi, Hagai Netzer, Dan Maoz +3
We present preliminary results from a reverberation mapping program to measure the Broad Line Region size in high-redshift, high-luminosity quasars. The observations are carried ou…
Observational Requirements for High-Fidelity Reverberation Mapping
Keith Horne, Bradley M. Peterson, Stefan J. Collier +1
We present a series of simulations to demonstrate that high-fidelity velocity-delay maps of the emission-line regions in active galactic nuclei can be obtained from time-resolved s…
Optical Monitoring of NLS1s at the Wise Observatory
Ohad Shemmer, Hagai Netzer
We report the preliminary results of a spectrophotometric monitoring program of Narrow-Line Seyfert 1 galaxies conducted at the Wise Observatory in 1999. The data we collected will…
Discovery of Narrow X-ray Absorption Lines from NGC 3783 with the Chandra HETGS
Shai Kaspi, W. N. Brandt, Hagai Netzer +4
We present the first grating-resolution X-ray spectra of the Seyfert 1 galaxy NGC 3783, obtained with the High Energy Transmission Grating Spectrometer on the Chandra X-ray Observa…
BLR Modeling: A New Approach
Shai Kaspi, Hagai Netzer
We present a new scheme for modeling the broad line region in active galactic nuclei. It involves photoionization calculations applied to a number of variable emission lines at {\i…
