The First Reported Infrared Emission from the SN 1006 Remnant
P. Frank Winkler, Brian J. Williams, William P. Blair +5
We report results of infrared imaging and spectroscopic observations of the SN 1006 remnant, carried out with the Spitzer Space Telescope. The 24 micron image from MIPS clearly sho…
Jet Luminosity From Neutrino-Dominated Accretion Flows in Gamma-Ray Bursts
Norita Kawanaka, Tsvi Piran, Julian H. Krolik
A hyperaccretion disk formed around a stellar mass black hole is a plausible model for the central engine that powers gamma-ray bursts (GRBs). If the central black hole rotates and…
Cygnus X-3's Little Friend
Michael L. McCollough, Randall K. Smith, Lynne Valencic
Using the unique X-ray imaging capabilities of the Chandra observatory, a 2006 observation of Cygnus X-3 has provided insight into a singular feature associated with this well-know…
The Metal Aversion of LGRBs
J. F. Graham, A. S. Fruchter
Recently, it has been suggested that the metallicity aversion of long-duration gamma-ray bursts (LGRBs) is not intrinsic to their formation, but rather a consequence of the anti-co…
Time Scales in Tidal Disruption Events
Tsvi Piran, Julian Krolik
We explore the temporal structure of tidal disruption events pointing out the corresponding transitions in the lightcurves of the thermal accretion disk and of the jet emerging fro…
Chandra Observations of 3C Radio Sources with z<0.3 II: completing the snapshot survey
F. Massaro, G. R. Tremblay, D. E. Harris +14
We report on the second round of Chandra observations of the 3C snapshot survey developed to observe the complete sample of 3C radio sources with z<0.3 for 8 ksec each. In the firs…
Multiwavelength campaign on Mrk 509 XII. Broad band spectral analysis
P. -O. Petrucci, S. Paltani, J. Malzac +12
(Abridged) The simultaneous UV to X-rays/gamma rays data obtained during the multi-wavelength XMM/INTEGRAL campaign on the Seyfert 1 Mrk 509 are used in this paper and tested again…
Contribution of the accretion disk, hot corona, and obscuring torus to the luminosity of Seyfert galaxies: INTEGRAL and Spitzer observations
S. Sazonov, S. P. Willner, A. D. Goulding +12
We estimate the relative contributions of the supermassive black hole (SMBH) accretion disk, corona, and obscuring torus to the bolometric luminosity of Seyfert galaxies, using Spi…
Simulating SZ intensity maps of giant AGN cocoons
D. A. Prokhorov, A. Moraghan, V. Antonuccio-Delogu +1
We perform relativistic hydrodynamic simulations of the formation and evolution of AGN cocoons produced by very light powerful jets. We calculate the intensity maps of the Sunyaev-…
Recovery of the Historical SN1957D in X-rays with Chandra
Knox S. Long, William P. Blair, L. E. H. Godfrey +6
SN1957D, located in one of the spiral arms of M83, is one of the small number of extragalactic supernovae that has remained detectable at radio and optical wavelengths during the d…
Multiwavelength campaign on Mrk 509: Reverberation of the Fe Kalpha line
G. Ponti, M. Cappi, E. Costantini +17
We report on a detailed study of the Fe K emission/absorption complex in the nearby, bright Seyfert 1 galaxy Mrk 509. The study is part of an extensive XMM-Newton monitoring consis…
X-ray Spectra from MHD Simulations of Accreting Black Holes
Jeremy D. Schnittman, Julian H. Krolik, Scott C. Noble
We present the results of a new global radiation transport code coupled to a general relativistic magneto-hydrodynamic simulation of an accreting, non-rotating black hole. For the…
X-ray emission from star-forming galaxies - III. Calibration of the Lx-SFR relation up to redshift z1.3
S. Mineo, M. Gilfanov, B. D. Lehmer +2
We investigate the relation between total X-ray emission from star-forming galaxies and their star formation activity. Using nearby late-type galaxies and ULIRGs from Paper I and s…
The Chandra X-ray point source catalog in the DEEP2 Galaxy Redshift Survey fields
A. D. Goulding, W. R. Forman, R. C. Hickox +8
We present the X-ray point-source catalog produced from the Chandra Advanced CCD Imaging Spectrometer (ACIS-I) observations of the combined \sim3.2 deg2 DEEP2 (XDEEP2) survey field…
X-ray Binary Evolution Across Cosmic Time
Tassos Fragos, Bret Lehmer, Michael Tremmel +8
High redshift galaxies permit the study of the formation and evolution of X-ray binary populations on cosmological timescales, probing a wide range of metallicities and star-format…
The Nature of the Compton-thick X-ray Reprocessor in NGC 4945
Tahir Yaqoob
We present an exhaustive methodology for fitting Compton-thick X-ray reprocessor models to obscured AGNs and for interpreting the results. We focus on the MYTORUS model but also ut…
An Archival Chandra and XMM-Newton Survey of Type 2 Quasars
Jianjun Jia, Andrew Ptak, Timothy Heckman +1
(Abridged) We analyzed the {\it Chandra} and {\it XMM-Newton} archival observations for 72 type 2 quasars at . These objects were was selected based on the [O III]5007 opti…
A Chandra observation of the ultraluminous infrared galaxy IRAS 19254--7245 (the Superantennae): X-ray emission from the Compton-thick AGN and the diffuse starburst

We present a {\it Chandra} observation of IRAS 19254--7245, a nearby ULIRG also known as {\it the Superantennae}. The high spatial resolution of {\it Chandra} allows us to disentan…
Circumbinary MHD Accretion into Inspiraling Binary Black Holes
Scott C. Noble, Bruno C. Mundim, Hiroyuki Nakano +4
As 2 black holes bound to each other in a close binary approach merger their inspiral time becomes shorter than the characteristic inflow time of surrounding orbiting matter. Using…
