A Possible X-Ray Periodicity at Several Tens Hours of a Ultra-Luminous Compact X-Ray Source in IC 342
M. Sugiho, J. Kotoku, K. Makishima +4
A long (155 hours) ASCA observation was performed of two ultra luminous compact X-ray sources, Source 1 and Source 2, in the spiral galaxy IC 342. While Source 1 that was in a hard…

Excess Hard X-ray Emission from the Obscured Low Luminosity AGN In the Nearby Galaxy M 51 (NGC 5194)
Yasushi Fukazawa, Naoko Iyomoto, Aya Kubota +2
We observed the nearby galaxy M~51 (NGC 5194) with BeppoSAX. The X-ray properties of the nucleus below 10 keV are almost the same as the ASCA results regarding the hard component a…

Spectral variability of Ultra Luminous Compact X-ray Sources in Nearby Spiral Galaxies
T. Mizuno, A. Kubota, K. Makishima
Using the X-ray data taken with ASCA, a detailed analysis was made of intensity and spectral variations of three ultra-luminous extra-galactic compact X-ray sources (ULXs); IC 342…
