Resolving the BLR in NGC 3783
P. Lira, M. Kishimoto, A. Robinson +5
We present results from very high signal-to-noise spectropolarimetric observations of the Seyfert 1 galaxy NGC 3783. Position Angle (PA) changes across the Balmer lines show that t…
The XMM-Newton wide-field survey in the COSMOS field: III. optical identification and multiwavelength properties of a large sample of X-ray selected sources
M. Brusa, G. Zamorani, A. Comastri +31
[ABRIGED] We present the optical identification of a sample of 695 X-ray sources detected in the first 1.3 deg^2 of the XMM-COSMOS survey, down to a 0.5-2 keV (2-10 keV) limiting f…
The XMM-Newton wide-field survey in the COSMOS field: I. Survey description
G. Hasinger, N. Cappelluti, H. Brunner +21
We present the first set of XMM-Newton EPIC observations in the 2 square degree COSMOS field. The strength of the COSMOS project is the unprecedented combination of a large solid a…
Rapid N_H changes in NGC 4151
S. Puccetti, F. Fiore, G. Risaliti +4
We have analyzed the two longest (elapsed time > 3 days) BeppoSAX observations of the X-ray brightest Seyfert galaxy, NGC 4151, to search for spectral variability on time-scales fr…
Chandra and Far Ultraviolet Spectroscopic Explorer Observations of z~0 Warm-Hot Gas Toward PKS 2155-304
Rik J. Williams, Smita Mathur, Fabrizio Nicastro +1
The X-ray bright z=0.116 quasar PKS 2155-304 is frequently observed as a Chandra calibration source, with a total of 483 ksec of Low Energy Transmission Grating (LETG) exposure tim…
The Extreme Physics Explorer
Martin Elvis
Some tests of fundamental physics - the equation of state at supra-nuclear densities, the metric in strong gravity, the effect of magnetic fields above the quantum critical value -…
A Detection of [CII] line emission in the z=4.7 QSO BR1202-0725
D. Iono, M. S. Yun, M. Elvis +6
We present ~3'' resolution imaging of the z=4.7 QSO BR1202-0725 at 900 micron from the Submillimeter Array. The two submillimeter continuum components are clearly resolved from eac…
Magellan Spectroscopy of AGN Candidates in the COSMOS Field
Jonathan R. Trump, Chris D. Impey, Patrick J. McCarthy +8
We present spectroscopic redshifts for the first 466 X-ray and radio-selected AGN targets in the 2 deg^2 COSMOS field. Spectra were obtained with the IMACS instrument on the Magell…
Spitzer IRS spectra of a large sample of Seyfert galaxies: a variety of infrared SEDs in the local AGN population
Catherine L. Buchanan, Jack F. Gallimore, Christopher P. O'Dea +5
We are conducting a large observing program with the Spitzer Space Telescope to determine the mid-to-far infrared spectral energy distributions of a well-defined sample of 87 nearb…
Interferometric 890 micron Images of High Redshift Submillimeter Galaxies
D. Iono, A. B. Peck, A. Pope +12
We present high resolution 890 micron images of two 20 mJy submillimeter galaxies, SMMJ123711+622212 and MIPS~J142824.0+352619, obtained using the Submillimeter Array (SMA). Using…
XMM-Newton View of the z>0 Warm-Hot Intergalactic Medium Toward Markarian 421
Rik J. Williams, Smita Mathur, Fabrizio Nicastro +1
The recent detection with Chandra of two warm-hot intergalactic medium (WHIM) filaments toward Mrk 421 by Nicastro et al. provides a measurement of the bulk of the "missing baryons…
