RHESSI as a Hard X-Ray Polarimeter
M. L. McConnell, J. M. Ryan, D. M. Smith +2
Polarization measurements of hard X-rays from solar flares can provide a direct handle on the extent to which the accelerated electrons are beamed, which, in turn, has important im…
Orbital and Super-Orbital Periods of 1E 1740.7-2942 and GRS 1758-258
D. M. Smith, W. A. Heindl, J. H. Swank
Five years of Rossi X-ray Timing Explorer (RXTE) observations of the Galactic black-hole candidates 1E 1740.7-2942 and GRS 1758-258 show a periodic modulation with amplitude 3-4% i…
Chandra High Resolution Camera Imaging of GRS 1758-258
W. A. Heindl, D. M. Smith
We observed the "micro-quasar" GRS 1758-258 four times with Chandra. Two HRC-I observations were made in 2000 September-October spanning an intermediate-to-hard spectral transition…
Long Term Variability of Cyg X-1 I. X-ray spectral-temporal correlations in the hard state
K. Pottschmidt, J. Wilms, M. A. Nowak +6
We present the long term evolution of the timing properties of the black hole candidate Cygnus X-1 in the 0.002-128 Hz frequency range as monitored from 1998 to 2001 with the RXTE.…
