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…
Extreme X-ray Behavior in the Low-Luminosity Active Nucleus of NGC 4395
E. C. Moran, M. Eracleous, K. M. Leighly +4
We present the results of a 17 ks Chandra observation of the nearby dwarf spiral galaxy NGC 4395, focusing on the X-ray properties of the moderate-mass black hole that resides in i…
X-ray Spectroscopy of BAL and Mini-BAL QSOs
S. C. Gallagher, W. N. Brandt, G. Chartas +1
BAL QSOs are notoriously faint X-ray sources, presumably due to extreme intrinsic absorption. However, several objects have begun to appear through the obscuration with recent X-ra…
Chandra X-ray Observations of the Quadruply Lensed Quasar RX J0911.4+0551
Nicholas D. Morgan, George Chartas, Michael Malm +5
We present results from X-ray observations of the quadruply lensed quasar RX J0911.4+0551 using data obtained with the Advanced CCD Imaging Spectrometer (ACIS) on board the Chandra…
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…
