HETE-2 Localization and Observations of the Short, Hard Gamma-Ray Burst GRB020531
D. Q. Lamb, G. R. Ricker, J. -L. Atteia +44
The {\it HETE-2} (hereafter \HETE) French Gamma Telescope (FREGATE) and the Wide-field X-ray Monitor (WXM) instruments detected a short ( msec in the FREGATE 85-300 k…
Probing the hard X-ray properties of high-redshift Radio-Quiet Quasars with ASCA
C. Vignali, A. Comastri, M. Cappi +3
This paper reports the X-ray spectral analysis of 5 high-redshift (z \ge 2) radio-quiet quasars observed by ASCA. A simple power law continuum plus cold Galactic absorption model w…
Evidence for ionized reprocessing in the X-ray spectrum of the Seyfert 1 Galaxy 1E1615+061
M. Guainazzi, L. Piro, M. Capalbi +3
The Seyfert 1 galaxy 1E1615+061 was observed to display a very steep and intense soft X-ray spectrum during a HEAO-1 A2 observation in the 1978. Such an exceptionally soft X-ray st…
The X-ray spectrum of the Gamma Bright Quasar S5 0836+710
A. Comastri, M. Cappi, M. Matsuoka
We present the results of an ASCA observation of the high redshift flat spectrum radio quasar S5 0836+710. The keV X-ray spectrum is remarkably flat with …
Is the X-ray spectrum of the Seyfert 2 galaxy NGC5252 intrinsically flat?
M. cappi, T. Mihara, M. Matsuoka +3
The first X-ray observation of the Seyfert 2 galaxy NGC5252 is reported. ASCA collected photons/detector enough to perform an accurate spectral analysis of this source.…
