WFPC2 Imaging of Quasar Environments: A Comparison of LBQS and HST Archive Quasars
R. A. Finn, C. D. Impey, E. J. Hooper
We present Hubble Space Telescope (HST) Wide Field Planetary Camera 2 (WFPC2) data on the large-scale environments of 16 0.39 < z < 0.51 quasars from the Large Bright Quasar Survey…
The Chandra Multi-wavelength Project (ChaMP): a serendipitous survey with Chandra archival data
B. J. Wilkes, P. Green, R. Brissenden +34
The launch of the Chandra X-ray Observatory in July 1999 opened a new era in X-ray astronomy. Its unprecedented, <0.5" spatial resolution and low background are providing views of…
The Far-Infrared emission of Radio Loud and Radio Quiet Quasars
M. Polletta, T. J. -L. Courvoisier, E. J. Hooper +1
Continuum observations at radio, millimetre, infrared and soft X-ray energies are presented for a sample of 22 quasars, consisting of flat and steep spectrum radio loud, radio inte…
Infrared Properties of High Redshift and X-ray Selected AGN Samples
Belinda J. Wilkes, Eric J. Hooper, Kim K. McLeod +7
The NASA/ISO Key Project on active galactic nuclei (AGN) seeks to better understand the broad-band spectral energy distributions (SEDs) of these sources from radio to X-rays, with…
The ISO/NASA Key Project on AGN Spectral Energy Distributions (Characteristics of the ISO Data)
Eric J. Hooper, Belinda J. Wilkes, Kim K. McLeod +5
The U.S. ISO Key Project on quasar spectral energy distributions seeks to better understand the very broad-band emission features of quasars from radio to X-rays. A key element of…
The Far-infrared Continuum of Quasars
Belinda J. Wilkes, Eric J. Hooper, Kim K. McLeod +5
ISO provides a key new far-infrared window through which to observe the multi-wavelength spectral energy distributions (SEDs) of quasars and active galactic nuclei (AGN). It allows…
