The complete spectrum of the neutron star X-ray binary 4U0614+091

S. Migliari, J. A. Tomsick, J. C. A. Miller-Jones +6

We observed the neutron star (NS) ultra-compact X-ray binary 4U0614+091 quasi-simultaneously in the radio band (VLA), mid-IR/IR (Spitzer/MIPS and IRAC), near-IR/optical (SMARTS), o…

Suzaku observation of IGR J16318-4848

L. Barragán, J. Wilms, K. Pottschmidt +4

We report on the first Suzaku observation of IGR J16318-4848, the most extreme example of a new group of highly absorbed X-ray binaries that have recently been discovered by the In…

Truncation of the Inner Accretion Disk around a Black Hole at Low Luminosity

John A. Tomsick, Kazutaka Yamaoka, Stephane Corbel +3

Most black hole binaries show large changes in X-ray luminosity caused primarily by variations in mass accretion rate. An important question for understanding black hole accretion…

Discovery of a new Soft Gamma Repeater: SGR J0418+5729

A. J. van der Horst, V. Connaughton, C. Kouveliotou +31

On 2009 June 5, the Gamma-ray Burst Monitor (GBM) onboard the Fermi Gamma-ray Space Telescope triggered on two short, and relatively dim bursts with spectral properties similar to…

The nature of the X-ray binary IGR J19294+1816 from INTEGRAL, RXTE, and Swift observations

J. Rodriguez, J. A. Tomsick, A. Bodaghee +4

We report the results of a high-energy multi-instrumental campaign with INTEGRAL, RXTE, and Swift of the recently discovered INTEGRAL source IGR J19294+1816. The Swift/XRT data all…

Discovery of a highly energetic pulsar associated with IGR J14003-6326 in a young uncataloged Galactic supernova remnant G310.6-1.6

M. Renaud, V. Marandon, E. V. Gotthelf +6

We report the discovery of 31.18 ms pulsations from the INTEGRAL source IGR J14003-6326 using the Rossi X-ray Timing Explorer (RXTE). This pulsar is most likely associated with the…

The infrared/X-ray correlation of GX 339-4: Probing hard X-ray emission in accreting black holes

M. Coriat, S. Corbel, M. M. Buxton +4

GX 339-4 has been one of the key sources for unravelling the accretion ejection coupling in accreting stellar mass black holes. After a long period of quiescence between 1999 and 2…

Following the 2008 outburst decay of the black hole candidate H1743-322 in X-ray and radio

P. G. Jonker, J. Miller-Jones, J. Homan +10

In this Paper we report on radio (VLA and ATCA) and X-ray (RXTE, Chandra and Swift) observations of the outburst decay of the transient black hole candidate H1743-322 in early 2008…

RHESSI Tests of Quasi-Thermal Gamma-Ray Burst Spectral Models

Eric C. Bellm

Prompt gamma-ray burst spectra evolve on short time scales, suggesting that time-resolved spectral fits may help diagnose the still unknown prompt emission mechanism. We use broad-…

A new analysis of the short-duration, hard-spectrum GRB 051103, a possible extragalactic SGR giant flare

K. Hurley, A. Rowlinson, E. Bellm +34

GRB 051103 is considered to be a candidate soft gamma repeater (SGR) extragalactic giant magnetar flare by virtue of its proximity on the sky to M81/M82, as well as its time histor…

Two Rapidly Variable Galactic X-ray Transients Observed with Chandra, XMM and Suzaku

C. O. Heinke, J. A. Tomsick, F. Yusef-Zadeh +1

We have identified two moderately bright, rapidly variable transients in new and archival X-ray data near the Galactic center. Both objects show strong, flaring variability on time…

Radiation from relativistic shocks with turbulent magnetic fields

K. -I. Nishikawa, J. Niemiec, M. Medvedev +10

Using our new 3-D relativistic electromagnetic particle (REMP) code parallelized with MPI, we investigated long-term particle acceleration associated with a relativistic electron-p…

The first outburst of the new magnetar candidate SGR 0501+4516

Nanda Rea, GianLuca Israel, Roberto Turolla +17

We report here on the outburst onset and evolution of the new Soft Gamma Repeater SGR 0501+4516. We monitored the new SGR with XMM-Newton starting on 2008 August 23, one day after…

Identifications of Five INTEGRAL Sources via Optical Spectroscopy

Suzanne C. Butler, John A. Tomsick, Sylvain Chaty +6

The International Gamma-Ray Astrophysics Laboratory (INTEGRAL) is discovering hundreds of new hard X-ray sources, many of which remain unidentified. We report on optical spectrosco…
