X-ray hiccups from SgrA* observed by XMM-Newton. The second brightest flare and three moderate flares caught in half a day
D. Porquet, N. Grosso, P. Predehl +14
[truncated] In Spring 2007, we observed SgrA* with XMM with a total exposure of ~230ks. We have performed timing and spectral analysis of the new X-ray flares detected during this…
Probing Elemental Abundances in SNR 1987A Using XMM-Newton
Kevin Heng, Frank Haberl, Bernd Aschenbach +1
We report on the latest (2007 Jan) observations of supernova remnant (SNR) 1987A from the XMM-Newton mission. Since the 2003 May observations of Haberl et al. (2006), 11 emission l…
Evolution of supermassive black holes
Andreas Mueller, Guenther Hasinger
The cosmological evolution of supermassive black holes (SMBHs) seems to be intimately linked to their host galaxies. Active galactic nuclei (AGN) can be probed by deep X-ray survey…
The XMM-Newton wide-field survey in the COSMOS field: V. Angular Clustering of the X-ray Point Sources
Takamitsu Miyaji, Giovanni Zamorani, Nico Cappelluti +9
We present the first results of the measurements of angular auto-correlation functions (ACFs) of X-ray point sources detected in the XMM-Newton observations of the 2 deg2 COSMOS fi…
The XMM-Newton Survey in the Marano Field I. The X-ray data and optical follow-up
M. Krumpe, G. Lamer, A. D. Schwope +6
We report on a medium deep XMM-Newton survey of the Marano Field and optical follow-up observations. The mosaicked XMM-Newton pointings in this optical quasar survey field cover 0.…
Robust quantitative measures of cluster X-ray morphology, and comparisons between cluster characteristics
Yasuhiro Hashimoto, Hans Boehringer, J. Patrick Henry +2
To investigate the relationships between dynamical status and other important characteristics of galaxy clusters, we conducted a study of X-ray cluster morphology using a sample of…
