Spectroscopic Confirmation Of An Extreme Starburst At Redshift 4.547
Peter Capak, C. L. Carilli, N. Lee +22
We report the spectroscopic confirmation of a sub-mm galaxy (SMG) at z=4.547 with an estimated L_IR=0.5-2.0x10^13 L_sun. The spectra, mid-IR, and X-ray properties indicate the bolo…
The Spitzer Legacy Survey of the HST-ACS 2 sq. deg. COSMOS Field: survey strategy and first analysis
D. B. Sanders, M. Salvato, H. Aussel +39
The Spitzer-COSMOS survey (S-COSMOS) is a Legacy program (Cycles 2+3) designed to carry out a uniform deep survey of the full 2 sq deg COSMOS field in all seven Spitzer bands (3.6,…
The XMM-Newton wide-field survey in the COSMOS field. IV: X-ray spectral properties of Active Galactic Nuclei
V. Mainieri, G. Hasinger, N. Cappelluti +25
We present a detailed spectral analysis of point-like X-ray sources in the XMM-COSMOS field. Our sample of 135 sources only includes those that have more than 100 net counts in the…
A Potential Galaxy Threshing System in the Cosmos Field
S. S. Sasaki, Y. Taniguchi, N. Scoville +26
We report on the discovery of a new potential galaxy threshing system in the COSMOS 2 square degree field using the prime-focus camera, Suprime-Cam, on the 8.2 m Subaru Telescope.…
Accretion and nuclear activity of quiescent supermassive black holes. I: X-ray study
Roberto Soria, Giuseppina Fabbiano, Alister W. Graham +5
We have studied the nuclear activity in a sample of six quiescent early-type galaxies, with new Chandra data and archival HST optical images. Their nuclear sources have X-ray lumin…
A panchromatic view of AGN
G. Risaliti, M. Elvis
We review the continuum emission of Active Galactic Nuclei (AGN) over the entire electromagnetic spectrum. After a brief historical introduction, we describe the main spectral prop…
Heavy X-ray Absorption in Soft X-ray Weak Active Galactic Nuclei
S. C. Gallagher, W. N. Brandt, A. Laor +4
Recent ROSAT studies have identified a significant population of Active Galactic Nuclei (AGN) that are notably faint in soft X-rays relative to their optical fluxes. Are these AGN…
The complex X-ray absorbers of NGC 3516 observed by BeppoSAX
E. Costantini, F. Nicastro, A. Fruscione +10
In this paper we present the analysis of two broad band (0.1-150 keV) BeppoSAX observations of the Seyfert 1 galaxy NGC 3516. The two observations were taken 4 months apart, on 199…
Heavy and Complex X-ray Absorption Towards the Nucleus of Markarian 6
John Feldmeier, W. N. Brandt, M. Elvis +3
We have used the ASCA satellite to make the first X-ray spectra of Markarian 6, a bright Seyfert 1.5 galaxy with complex and variable permitted lines, an ionization cone, and remar…
ASCA observations of two steep soft X-ray quasars
F. Fiore, G. Matt, M. Cappi +6
Steep soft X-ray (0.1-2 keV) quasars share several unusual properties: narrow Balmer lines, strong FeII emission, large and fast X-ray variability, rather steep 2-10 keV spectrum.…
