Discovery of X-ray Pulsations from the INTEGRAL Source IGR J11014-6103
J. P. Halpern, J. A. Tomsick, E. V. Gotthelf +6
We report the discovery of PSR J1101-6101, a 62.8 ms pulsar in IGR J11014-6103, a hard X-ray source with a jet and a cometary tail that strongly suggests it is moving away from the…
The Norma Arm Region Chandra Survey: X-ray Populations in the Spiral Arms
Francesca M. Fornasini, John A. Tomsick, Arash Bodaghee +6
We present a catalog of 1415 X-ray sources identified in the Norma arm region Chandra survey (NARCS), which covers a 2 deg x 0.8 deg region in the direction of the Norma spiral arm…
Initial Results from NuSTAR Observations of the Norma Arm
Arash Bodaghee, John A. Tomsick, Roman Krivonos +12
Results are presented for an initial survey of the Norma Arm gathered with the focusing hard X-ray telescope NuSTAR. The survey covers 0.2 deg of sky area in the 3-79 keV range…
Near-infrared spectroscopy of 20 new Chandra sources in the Norma Arm
Farid Rahoui, John A. Tomsick, Francesca M. Fornasini +2
We report on CTIO/NEWFIRM and CTIO/OSIRIS photometric and spectroscopic observations of 20 new X-ray (0.5-10 keV) emitters discovered in the Norma Arm Region Chandra Survey (NARCS)…
NuSTAR J163433-4738.7: A Fast X-ray Transient in the Galactic Plane
John A. Tomsick, Eric V. Gotthelf, Farid Rahoui +14
During hard X-ray observations of the Norma spiral arm region by the Nuclear Spectroscopic Telescope Array (NuSTAR) in 2013 February, a new transient source, NuSTAR J163433-4738.7,…
Long term variability of Cygnus X-1: VI. Energy-resolved X-ray variability 1999-2011
V. Grinberg, K. Pottschmidt, M. Böck +11
We present the most extensive analysis of Fourier-based X-ray timing properties of the black hole binary Cygnus X-1 to date, based on 12 years of bi-weekly monitoring with RXTE fro…
