Spectroscopy of Quasar Candidates from SDSS Commissioning Data
Xiaohui Fan, Michael A. Strauss, James Annis +9
The Sloan Digital Sky Survey has obtained images in five broad-band colors for several hundred square degrees. We present color-color diagrams for stellar objects, and demonstrate…
The optical/IR counterpart of the 3 July 1998 gamma-ray burst and its evolution
A. J. Castro-Tirado, M. R. Zapatero-Osorio, J. Gorosabel +21
We imaged the X-ray error box of GRB 980703, beginning 22.5 hours after the gamma--ray event, in both the optical R and near-infrared H bands. A fading optical/IR object was detect…
ASCA Discovery of an X-ray Pulsar in the Error Box of SGR1900+14
K. Hurley, P. Li, C. Kouveliotou +9
We present a 2 - 10 keV ASCA observation of the field around the soft gamma repeater SGR1900+14. One quiescent X-ray source was detected in this observation, and it was in the SGR…
VSOP imaging of S5 0836+710: a close-up on plasma instabilities in the jet
A. P. Lobanov, T. P. Krichbaum, A. Witzel +6
The luminous high-redshift (z=2.17) quasar S5 0836+710 has been observed at 5GHz with the VSOP. We compare the properties of three images obtained from the observation: a low-resol…
Discovery of Correlated Behavior Between the HXR and the Radio Bands in Cygnus X-3
M. L. McCollough, C. R. Robinson, S. N. Zhang +8
Using CGRO/BATSE hard X-ray (HXR) data and GHz radio monitoring data from the Green Bank Interferometer (GBI), we have performed a long term study ( 1800 days) of the unusual…
The Sloan Digital Sky Survey Photometric Camera
J. Gunn, M. Carr, C. Rockosi +1
We have constructed a large format mosaic CCD camera for the Sloan Digital Sky Survey. The camera consists of two arrays, a photometric array which uses 30 2048 x 2048 SITe/Tektron…
