Broad band X-ray spectrum of KS 1947+300 with BeppoSAX
S. Naik, P. J. Callanan, B. Paul +1
We present results obtained from three BeppoSAX observations of the accretion-powered transient X-ray pulsar KS 1947+300 carried out during the declining phase of its 2000 November…
Detection of hard X-ray pulsations and a strong iron K_beta emission line during an extended low state of GX 1+4
S. Naik, B. Paul, P. J. Callanan
We present here results obtained from a detailed timing and spectral analysis of three BeppoSAX observations of the binary X-ray pulsar GX 1+4 carried out in August 1996, March 199…
HST/ACS Imaging of Omega Centauri: Optical Counterpart for the Quiescent Low-Mass X-Ray Binary
D. Haggard, A. M. Cool, J. Anderson +5
We report the discovery of an optical counterpart to a quiescent neutron star in the globular cluster Omega Centauri (NGC 5139). The star was found as part of our wide-field imagin…
Optical Spectral Monitoring of XTE J1118+480 in Outburst: Evidence for a Precessing Accretion Disk?
M. A. P. Torres, P. J. Callanan, M. R. Garcia +7
We present spectroscopic observations of the X-ray transient XTE J1118+480 acquired during different epochs following the 2000 March outburst. We find that the emission line profil…
