X-ray intensity-hardness correlation in Cyg X-1
Linqing Wen, Wei Cui, Hale V. Bradt
Using data from the All-Sky Monitor aboard the Rossi X-ray Timing Explorer (RXTE), we found that the 1.5-12 keV X-ray count rate of Cyg X-1 is, on time scales from 90 seconds to at…

Localizations of Thirteen Gamma-ray Bursts by the All-Sky Monitor on RXTE
D. A. Smith, A. M. Levine, H. V. Bradt +9
The All-Sky Monitor (ASM) on the Rossi X-ray Timing Explorer (RXTE) has been used to localize thirteen confirmed X-ray counterparts to Gamma-Ray Bursts (GRBs) detected over three y…

X-ray Orbital Modulation of Cygnus X-1
Linqing Wen, Wei Cui, Alan M. Levine +1
We have analyzed over 2 years of RXTE/ASM data for Cygnus X-1. We have detected the 5.6-day orbital period in Lomb-Scargle periodograms of both light curves and hardness ratios whe…
