Low-Energy Astrophysics: Stimulating the Reduction of Energy Consumption in the Next Decade
P. J. Marshall, N. Bennert, E. S. Rykoff +27
In this paper we address the consumption of energy by astronomers while performing their professional duties. Although we find that astronomy uses a negligible fraction of the US e…
Chandra Observations of 12 Luminous Red Quasars
Tanya Urrutia, Mark Lacy, Michael D. Gregg +1
We present results of a study of 12 dust-reddened quasars with 0.4 < z < 2.65 and reddenings in the range 0.15 < E(B-V) < 1.7. We obtained ACIS-S X-ray spectra of these quasars, es…
Imaging and spectroscopy of galaxies associated with two z~0.7 damped Lyman-alpha absorption systems
Mark Lacy, Robert H. Becker, Lisa J. Storrie-Lombardi +4
We have identified galaxies near two quasars which are at the redshift of damped Lyman-alpha (DLA) systems in the UV spectra of the quasars. Both galaxies are actively forming star…
A serendipitous survey for galaxy clusters by the XMM-Newton Survey Science Center
A. D. Schwope, G. Lamer, D. Burke +5
We describe the initial results of a programme to detect and identify extended X-ray sources found serendipitously in XMM-Newton observations. We have analysed 186 EPIC-PN images a…
