Difference Image Analysis of the OGLE-II Bulge Data. III. Catalog of 200,000 Candidate Variable Stars
P. R. Wozniak, A. Udalski, M. Szymanski +4
We present the first edition of a catalog of variable stars from OGLE-II Galactic Bulge data covering 3 years: 1997-1999. Typically 200-300 I band data points are available in 49 f…
HST/STIS observations of the HeII Gunn-Peterson effect towards HE 2347-4342
Alain Smette, Sara R. Heap, Gerard M. Williger +3
We present an HST STIS spectrum of the HeII Gunn-Peterson effect towards HE2347-4342. Compared to the previous HST GHRS data obtained by Reimers et al. (1997), the STIS spectrum ha…
Radiative Transfer in 3D
M. Juvela, P. Padoan
The high resolution and sensitivity provided by proposed Atacama Large Millimeter Array will reveal new small scale structures in many sources, e.g. star forming regions. Such inho…
The ROSAT Deep Survey IV. A distant lensing cluster of galaxies with a bright arc
G. Hasinger, R. Giacconi, J. E. Gunn +7
An unusual double-lobed extended X-ray source (RX J105343+5735) is detected in the ROSAT ultra-deep HRI image of the Lockman Hole. The angular size of the source is 1.7 X 0.7 arcmi…
