Precise Interplanetary Network Localization of the Bursting Pulsar GRO J1744-28
K. Hurley, C. Kouveliotou, T. Cline +8
We analyze 426 observations of the bursting pulsar GRO J1744-28 by Ulysses and BATSE. Triangulating each burst, and statistically combining the triangulation annuli, we obtain a 3…
FAUST Observations in the Fourth Galactic Quadrant
N. Brosch, A. Brook, L. Wisotzki +4
We analyze UV observations with FAUST of four sky fields in the general direction of the fourth Galactic quadrant, in which we detect 777 UV sources. This is ~50% more than detecte…
EUVE Observations of clusters of galaxies: Virgo and M87
Thomas W. Berghoefer, Stuart Bowyer, Eric Korpela
We present results of a re-analysis of archival EUVE data of the central region of the Virgo cluster. We employ the new analysis method developed by Bowyer, Berghöfer & Korpela (19…
Gamma-Ray Burst Arrival-Time Localizations: Simultaneous Observations by Ulysses, Pioneer Venus Orbiter, SIGMA, WATCH, and PHEBUS
K. Hurley, J. Laros, S. Brandt +11
Between the launch of the Ulysses spacecraft in 1990 October and the entry of Pioneer Venus Orbiter (PVO) into the atmosphere of Venus in 1992 October, concurrent coverage by Ulyss…
The 4.5 +/- 0.5 Soft Gamma Repeaters in Review
K. Hurley
Four Soft Gamma Repeaters (SGRs) have now been identified with certainty, and a fifth has possibly been detected. I will review their X-ray and gamma-ray properties in both outburs…
A Gamma-Ray Burst Bibliography, 1973-1999
K. Hurley
On the average, one new publication on cosmic gamma-ray bursts enters the literature every day. The total number now exceeds 4100. I present here a complete bibliography which can…
Simultaneous Observations of GRS 1758-258 in 1997 by VLA, IRAM, SEST, RXTE and OSSE: Spectroscopy and Timing
D. Lin, I. A. Smith, E. P. Liang +6
We report the results of our multi-wavelength observations of GRS 1758-258 made in August 1997. The energy bands include radio, millimeter, X-ray, and gamma-ray. The observations e…
EUV Emission in Abell 1795, Abell 2199, and the Coma Cluster
Stuart Bowyer, Thomas Berghoefer, Eric Korpela
We report new EUV data on the cluster of galaxies Abell 1795. These data were taken well away from a detector defect which could have compromised earlier results on this cluster. O…
Hard Burst Emission from the Soft Gamma Repeater SGR 1900+14
Peter M. Woods, Chryssa Kouveliotou, Jan van Paradijs +7
We present evidence for burst emission from SGR 1900+14 with a power-law high energy spectrum extending beyond 500 keV. Unlike previous detections of high energy photons during bur…
ASCA Observation of the quiescent X-ray counterpart to SGR1627-41
K. Hurley, T. Strohmayer, P. Li +9
We present a 2 - 10 keV ASCA observation of the field around the soft gamma repeater SGR1627-41. A quiescent X-ray source was detected in this observation whose position was consis…
Pinwheel nebula around WR 98a
J. D. Monnier, P. G. Tuthill, W. C. Danchi
We present the first near-infrared images of dusty Wolf-Rayet star WR 98a. Aperture masking interferometry has been utilized to recover images at the diffraction-limit of the Keck-…
Prompt Optical Emission from Gamma-ray Bursts
Robert Kehoe, Carl Akerlof, Richard Balsano +19
The Robotic Optical Transient Search Experiment (ROTSE) seeks to measure contemporaneous and early afterglow optical emission from gamma-ray bursts (GRBs). The ROTSE-I telescope ar…
Discovery of kHz Fluctuations in Centaurus X-3: Evidence for Photon Bubble Oscillations (PBO) and Turbulence in a High Mass X-ray Binary Pulsar
J. Garrett Jernigan, Richard I. Klein, Jonathan Arons
We report the discovery of kHz fluctuations, including quasi-periodic oscillations (QPO) at ~330 Hz and ~760 Hz and a broadband kHz continuum in the power density spectrum of the h…
Observations of a possible new soft gamma repeater, SGR1801-23
T. Cline, D. D. Frederiks, S. Golenetskii +4
We report on two observations of a soft bursting source in 1997 June, whose time histories and energy spectra are consistent with those of the soft gamma repeaters. The source can…
Far Ultraviolet Absolute Flux of alpha Virginis
Carmen Morales, Joaquin Trapero, Jose F. Gomez +7
We present the far ultraviolet spectrum of alpha Virginis taken with EURD spectrograph on-board MINISAT-01. The spectral range covered is from ~900 to 1080 A with 5 A spectral reso…
Diffuse Galactic Soft Gamma-Ray Emission
S. E. Boggs, R. P. Lin, S. Slassi-Sennou +2
The Galactic diffuse soft gamma-ray (30-800 keV) emission has been measured from the Galactic Center by the HIREGS balloon-borne germanium spectrometer to determine the spectral ch…
Discovery of the Optical Transient of the Gamma Ray Burst 990308
Bradley E. Schaefer, J. A. Snyder, J. Hernandez +53
The optical transient of the faint Gamma Ray Burst 990308 was detected by the QUEST camera on the Venezuelan 1-m Schmidt telescope starting 3.28 hours after the burst. Our photomet…
