The 22-Month Swift-BAT All-Sky Hard X-ray Survey
J. Tueller, W. H. Baumgartner, C. B. Markwardt +36
We present the catalog of sources detected in the first 22 months of data from the hard X-ray survey (14--195 keV) conducted with the BAT coded mask imager on the \swift satellite.…
X-raying the Ultraluminous Infrared Starburst Galaxy and Broad Absorption Line QSO, Markarian 231, with Chandra
S. C. Gallagher, W. N. Brandt, G. Chartas +2
With 40 ks of Chandra ACIS-S3 exposure, new information on both the starburst and QSO components of the X-ray emission of Markarian 231, an ultraluminous infrared galaxy and Broad…
Gamma-loud quasars: a view with BeppoSAX
F. Tavecchio, L. Maraschi, G. Ghisellini +12
We present SAX observations of the -ray emitting quasars 0836+710, 1510-089 and 2230+114. All the objects have been detected in the PDS up to 100 keV and have extremely…
The Gamow Explorer: A gamma-ray burst observatory to study the high redshift universe and enable multi-messenger astrophysics
N. E. White, F. E. Bauer, W. Baumgartner +63
The Gamow Explorer will use Gamma Ray Bursts (GRBs) to: 1) probe the high redshift universe (z > 6) when the first stars were born, galaxies formed and Hydrogen was reionized; and…
Deep Chandra and multicolor HST follow-up of the jets in two powerful radio quasars
R. Sambruna, M. Gliozzi, D. Donato +5
We present deep (70-80 ks) Chandra and multicolor HST ACS images of two jets hosted by the powerful quasars 1136-135 and 1150+497, together with new radio observations. The sources…
Chandra high resolution spectroscopy of the circumnuclear matter in the Broad Line Radio Galaxy 3C445
J. N. Reeves, J. Gofford, V. Braito +1
We present evidence for X-ray line emitting and absorbing gas in the nucleus of the Broad-Line Radio Galaxy (BLRG), 3C 445. A 200ks Chandra LETG observation of 3C 445 reveals the p…
Swift and infra-red observations of the blazar 3C~454.3 during the giant X-ray flare of May 2005
P. Giommi, A. J. Blustin, M. Capalbi +16
We present the results of a series of Swift and quasi simultaneous ground-based infra-red observations of the blazar 3C 454.3 carried out in April-May 2005 when the source was 10 t…
Wide-Field InfraRed Survey Telescope (WFIRST) Final Report
J. Green, P. Schechter, C. Baltay +51
In December 2010, NASA created a Science Definition Team (SDT) for WFIRST, the Wide Field Infra-Red Survey Telescope, recommended by the Astro 2010 Decadal Survey as the highest pr…
Long-Term X-Ray and TeV variability of Mrk 501
M. Gliozzi, R. Sambruna, I. Jung +3
We present X-ray observations of the blazar Mrk501 obtained with RXTE during 1997, 1998, 1999, 2000, and 2004. The goal of this study is twofold: 1) characterize the long-term X-ra…
Simultaneous X-Ray and TeV Gamma-Ray Observations of the TeV Blazar Markarian 421 during February and May 2000
H. Krawczynski, R. Sambruna, A. Kohnle +3
In this paper we present the results of simultaneous observations of the TeV blazar Markarian 421 (Mrk 421) at X-ray and TeV Gamma-ray energies with the Rossi X-Ray Timing Explorer…
The Photo-z Infrared Telescope (PIRT) -- a space instrument for rapid follow up of high-redshift gamma-ray bursts and electromagnetic counterparts to gravitational wave events
M. Seiffert, A. Balady, T. -C. Chang +17
The Photo-z InfraRed Telescope (PIRT) is an instrument on the Gamow Explorer, currently proposed for a NASA Astrophysics Medium Explorer. PIRT works in tandem with a companion wide…
Gamma-ray loud quasars: a view with BeppoSAX
