Gamma-ray bursts from alternating-current jets
M. Sikora, M. C. Begelman, P. Coppi +1
We propose a gamma-ray burst scenario involving relativistic jets dominated by Poynting flux with alternating toroidal magnetic fields. Such a structure may arise naturally if the…
A near-infrared survey for Galactic Wolf-Rayet stars
N. L. Homeier, R. D. Blum, P. S. Conti +1
Initial results, techniques, and rationale for a near-infrared survey of evolved emission-line stars toward the Galactic Center are presented. We use images taken through narrow-ba…
NGC 3576 IRS 1 in the Mid Infrared
Cassio Barbosa, Augusto Damineli, Robert Blum +1
We present the results of high-resolution mid-infrared observations of the source NGC 3576 IRS 1. Near diffraction-limited images were taken at the Gemini South Observatory through…
Temporal Evolution of X-ray Lags in Cygnus X-1
K. Pottschmidt, J. Wilms, M. A. Nowak +3
We present the long term evolution of the frequency-dependent X-ray time lags of the black hole candidate Cygnus X-1 as measured in 1996 and 1998 with the Rossi X-ray Timing Explor…
The shock waves in decaying supersonic turbulence
Michael D. Smith, Mordecai-Mark Mac Low, Julia M. Zuev
We here analyse numerical simulations of supersonic, hypersonic and magnetohydrodynamic turbulence that is free to decay. Our goals are to understand the dynamics of the decay and…
RXTE Observations of Cygnus X-1: Broad-Band Spectra and High-Resolution Timing
K. Pottschmidt, J. Wilms, M. A. Nowak +3
We present results from a 20 ksec RXTE observation of the black hole candidate Cyg X-1. We apply self-consistent accretion disk corona models to these hard state data and show that…
