A Catalog of X-ray Point Sources from Two Megaseconds of Chandra Observations of the Galactic Center
M. P. Muno, F. E. Bauer, F. K. Baganoff +23
We present a catalog of 9017 X-ray sources identified in Chandra observations of a 2 by 0.8 degree field around the Galactic center. We increase the number of known X-ray sources i…
A New Class of Radio Pulsars - Back in 1982
M. Ali Alpar
Basic ideas about the torques on the neutron star and the existence of an equilibrium rotation period followed from the recognition that most X-ray binaries contain accretion power…
Discovery of kilohertz quasi-periodic oscillations and state transitions in the low-mass X-ray binary 1E~1724-3045 (Terzan 2)
D. Altamirano, M. van der Klis, M. Mendez +3
We have studied the rapid X-ray time variability in 99 pointed observations with the Rossi X-ray Timing Explorer (RXTE)'s Proportional Counter Array of the low-mass X-ray binary 1E…
Multiwavelength observations of the black hole candidate Swift J1753.5-0127
Paolo Soleri, Diego Altamirano, Rob Fender +8
We present preliminary results from the analysis of simultaneous multiwavelength observations of the black hole candidate Swift J1753.5-0127. The source is still continuing its out…
Millihertz Oscillation Frequency Drift Predicts the Occurrence of Type I X-ray Bursts
D. Altamirano, M. van der Klis, R. Wijnands +1
Millihertz quasi-periodic oscillations reported in three neutron-star low mass X-ray binaries have been suggested to be a mode of marginally stable nuclear burning on the neutron s…
Intermittent millisecond X-ray pulsations from the neutron-star X-ray transient SAX J1748.9-2021 in the globular cluster NGC 6440
D. Altamirano, P. Casella, A. Patruno +2
We report on intermittent X-ray pulsations with a frequency of 442.36 Hz from the neutron-star X-ray binary SAX J1748.9--2021 in the globular cluster NGC 6440. The pulsations were…
