ASCA Slew Survey
Ken Ebisawa, R. Fujimoto, Y. Ueda
We are systematically analyzing ASCA GIS data taken during the satellite attitude maneuver operation. Our motivation is to search for serendipitous hard X-ray sources and make the…
Near-Infrared Identification of the Dimmest X-ray Sources on the Galactic Plane with the ESO/NTT SOFI Camera
Ken Ebisawa, V. Beckmann, T. J. -L. Courvoisier +5
We have carried out a deep X-ray observation on a typical Galactic plane region with the Chandra ACIS-I instrument with unprecedented sensitivity and spatial resolution, and detect…
Study of the Largest Multiwavelength Campaign of the Microquasar GRS 1915+105
Y. Ueda, K. Yamaoka, C. Sanchez-Fernandez +17
We present the results from a multiwavelength campaign of GRS 1915+105 performed from 2000 April 16 to 25. This is one of the largest coordinated set of observations ever performed…
Chandra deep X-ray observation on the Galactic plane
K. Ebisawa, A. Bamba, H. Kaneda +4
Using the Chandra ACIS-I instruments, we have carried out the deepest X-ray observation on a typical Galactic plane region at l 28.5 deg, where no discrete X-ray sources have been…
The complex X-ray spectrum of the supersoft source MR Vel
Henk Bearda, Wouter Hartmann, Ken Ebisawa +5
We present the X-ray spectrum of MR Vel/RXJ0925.7-4758 obtained with the Medium Energy Grating spectrometer of the Chandra X-ray Telescope. The simplest models used by earlier auth…
