Evolution of the Synchrotron Spectrum in Mrk421 during the 1998 Campaign
Chiharu Tanihata, Tadayuki Takahashi, Jun Kataoka +1
The uninterrupted 7-day ASCA observations of the TeV blazar Mrk421 in 1998 have clearly revealed that X-ray flares occur repeatedly. In this paper, we present the results of the ti…
Detection of a Fully-resolved Compton Shoulder of the Iron K-alpha Line in the Chandra X-ray Spectrum of GX 301-2
Shin Watanabe, Masao Sako, Manabu Ishida +7
We report the detection of a fully-resolved, Compton-scattered emission line in the X-ray spectrum of the massive binary GX 301-2 obtained with the High Energy Transmission Grating…
Optical Identification of the ASCA Medium Sensitivity Survey in the Northern Sky: Nature of Hard X-ray-selected Luminous Active Galactic Nuclei
Masayuki Akiyama, Yoshihiro Ueda, Kouji Ohta +2
We present the results of optical spectroscopic identifications of a bright subsample of 2-10keV hard X-ray selected sources from the ASCA Medium Sensitivity Survey in the northern…
