The Power of Exploratory Chandra Observations
S. C. Gallagher, G. T. Richards, W. N. Brandt +1
With its excellent spatial resolution, low background, and hard-band response, the Chandra X-ray Observatory is ideal for performing exploratory surveys. These efficient, sensitive…
An Exploratory Chandra survey of Large Bright Quasar Survey broad absorption line QSOs
S. C. Gallagher, W. N. Brandt, G. Chartas +1
We are in the process of obtaining a complete sample of exploratory X-ray observations of broad absorption line (BAL) QSOs from the Large Bright Quasar Survey (LBQS). This survey i…
X-raying Active Galaxies with the New Generation of X-ray Observatories: Ionized Outflows and High-Redshift Studies
W. N. Brandt, S. C. Gallagher, S. Kaspi
We briefly review X-ray studies of ionized AGN outflows and high-redshift AGN. We discuss recent progress with Chandra and XMM-Newton as well as prospects and requirements for futu…
From Globular Clusters to Tidal Dwarfs: Structure Formation in Tidal Tails
Jane Charlton, Karen Knierman, Sally Hunsberger +4
Star clusters can be found in galaxy mergers, not only in central regions, but also in the tidal debris. In both the Eastern and Western tidal tails of NGC 3256 there are dozens of…
HST Images of Stephan's Quintet: Star Cluster Candidates in a Compact Group Environment
S. C. Gallagher, S. D. Hunsberger, J. C. Charlton +1
We present HST WFPC2 images of Stephan's Quintet which encompass three interacting galaxies and their associated tidal features. These deep, three-color (B, V, I) images indicate r…
X-ray Absorption in Radio-Quiet QSOs
W. N. Brandt, S. C. Gallagher, A. Laor +1
Major flows of ionized gas are thought to be present in the nuclei of most luminous QSOs, and absorption by these flows often has a significant effect upon the observed X-ray conti…
