Discovery of Spectral Transitions from Two Ultra-Luminous Compact X-Ray Sources in Ic342
Aya Kubota, Tsunefumi Mizuno, Kazuo Makishima +4
Two {\it ASCA} observations were made of two ultra-luminous compact X-ray sources (ULXs), Source 1 and Source 2, in the spiral galaxy IC 342. In the 1993 observation, Source 2 show…
Observations of the BL Lacertae Object OJ 287 in 1997 April and Nov ember
Naoki Isobe, Makoto Tashiro, Masahiko Sugiho +1
X-ray properties of the BL Lacertae object OJ 287, observed with ASCA on 1997 April 26 and November 17, are reported. The 0.5 -- 10 keV flux was lower than those obtained in previo…
X-ray measurements of the field and particle energy distributions in the west lobe of the radio galaxy NGC 1316 (Fornax A)
M. Tashiro, K. Makishima, N. Iyomoto +2
A follow-up X-ray study was made of the west lobe of the radio galaxy Fornax A, (NGC 1316) based on new ASCA observations made in 1997 for 98 ks, and incorporating the previous obs…
