Millisecond X-Ray Pulses from Cygnus X-1
J. F. Dolan
X-ray pulses with millisecond-long FWHM have been detected in RXTE (Rossi X-Ray Timing Explorer) observations of Cyg X-1. Their identity as short-timescale variations in the X-ray…
Very Low Frequency QPO in 4U1700-37
J. F. Dolan
Very low frequency (ν ~ 1.9 mHz) quasi-periodic oscillations (QPO) have been detected in 2 - 60 keV X-rays from 4U1700-37 using auto-correlation function analysis of RXTE archival…
A Search for Pulsars between 0.3 and 8 MeV using INTEGRAL
Joseph F. Dolan
The spectra of only a few pulsars are known in the low-energy gamma-ray region around 1 Mev. We searched for point sources of gamma-radiation in the 0.3-1 and 1-8 Mev bandpasses at…
A Search for Dying Pulse Trains in Cyg X-1 using RXTE
Joseph F. Dolan, Daria C Auerswald
Dying pulse trains (DPTs) pulses of radiation with decreasing intensity and decreasing intervals between them are predicted by General Relativity to occur from material spiraling i…
X-Ray and UV Orbital Phase Dependence in LMC X-3
Patricia T. Boyd, Alan P. Smale, Joseph F. Dolan
The black-hole binary LMC X-3 is known to be variable on time scales of days to years. We investigate X-ray and ultraviolet variability in the system as a function of the 1.7 day b…
STIS Near Ultraviolet Time-Tagged Spectra of the Crab Pulsar
Theodore R. Gull, Don J. Lindler, D. Michael Crenshaw +8
We present the spectrum and pulse profile of the Crab Pulsar in the near ultraviolet (1600-3200 Angstroms) observed with the Space Telescope Imaging Spectrograph (STIS) during the…
