Chandra Detection of X-ray Absorption Associated with a Damped Lyman Alpha System
Jill Bechtold, Aneta Siemiginowska, Thomas L. Aldcroft +2
We have observed three quasars, PKS 1127-145, Q 1331+171 and Q0054+144, with the ACIS-S aboard the Chandra X-ray Observatory, in order to measure soft X-ray absorption associated w…
Tests of a Structure for Quasars
Martin Elvis
The model I recently proposed for the structure of quasars (astro-ph/0008064) claims to unify all the emission, absorption and reflection phenomenology of quasars and AGN, and so i…
Clusters of galaxies among ROSAT blank field sources
I. Cagnoni, M. Elvis, D. -W. Kim +3
We present here an efficient method for selecting high luminosity and massive high redshift clusters of galaxies, crucially important tools in cosmology. By selecting bright and ex…
High-Resolution X-ray and Ultraviolet Spectroscopy of the Complex Intrinsic Absorption in NGC 4051 with Chandra and HST
M. J. Collinge, W. N. Brandt, Shai Kaspi +6
We present the results from simultaneous observations of the Narrow-Line Seyfert 1 galaxy NGC 4051 with the Chandra High Energy Transmission Grating Spectrometer and the HST Space…
The Chandra High Resolution Spectra of Mkn 421
F. Nicastro, A. Fruscione, M. Elvis +3
Mkn 421 was observed by Chandra twice, on November 5, 1999 as part of the Chandra calibration program, with the ACIS-HETG configuration, and on May 29, 2000 following our Target Of…
