UV observations of the galaxy cluster Abell 1795 with the optical monitor on XMM-Newton
J. P. Mittaz, J. S. Kaastra, T. Tamura +8
We present the results of an analysis of broad band UV observations of the central regions of Abell 1795 observed with the optical monitor on XMM-Newton. As have been found with ot…
RXTE observation of NGC 6240: a search for the obscured active nucleus
Yasushi Ikebe, Karen Leighly, Yasuo Tanaka +3
The wide-band energy spectrum of NGC6240 over the range 0.5-200keV is investigated using the RXTE and ASCA data. The RXTE data provide the spectrum beyond the ASCA range (0.5-10 ke…
X-ray Measurements of the Gravitational Potential Profile in the Central Region of the Abell 1060 Cluster of Galaxies
Takayuki Tamura, Kazuo Makishima, Yasushi Fukazawa +2
X-ray spectral and imaging data from ASCA and ROSAT were used to measure the total mass profile in the central region of Abell 1060, a nearby and relatively poor cluster of galaxie…
Detection of an X-Ray Hot Region in the Virgo Cluster of Galaxies with ASCA
K. Kikuchi, C. Itoh, A. Kushino +8
Based on mapping observations with ASCA, an unusual hot region with a spatial extent of 1 square degree was discovered between M87 and M49 at a center coordinate of R. A. = 12h 27m…
