Detection of Saturnian X-ray emission with XMM-Newton

Detection of Saturnian X-ray Emission with Xmm-newton

The giant planet Saturn was observed by XMM-Newton in September 2002. We present and analyse these XMM-Newton observations and compare our findings to the Chandra observations of Saturn. Contamination of the XMM-Newton data by optical light is found to be severe in the medium and thin filters, but with the thick filter all optical light is sufficiently blocked and the signal observed in the thi...

XMM - Newton Detection of X - ray Emission from the Bipolar Planetary Nebula Hb 5

We report the serendipitous detection by the XMM-Newton X-ray Observatory of an X-ray source at the position of the Type I (Heand N-rich) bipolar planetary nebula Hb 5. The Hb 5 X-ray source appears marginally resolved. While the small number of total counts (∼ 170) and significant off-axis angle of the X-ray source (∼ 7.8) precludes a definitive spatial analysis, the morphology of the X-ray em...

The origin of X - ray emission of two distant ( z > 1 ) cluster candidates with XMM - Newton

We present here a study of XMM-Newton data of two distant galaxy cluster candidates. One of these was discovered serendipitously in near infrared data, CL J0533-2411, the other one corresponds to the cluster EIS J0533-2412 part of the EIS cluster survey. The estimated redshift of CL J0533-2411 is z = 1.2 − 1.7. EIS J0533-2412 is a rich system (Λcl = 299), with a spectroscopically confirmed reds...

Revisiting the Soft X-ray Excess Emission in Clusters of Galaxies Observed with Xmm-newton

We analyze four XMM-Newton galaxy clusters (Abell 1795, Abell S1101, Abell 1835 and MKW 3s) in order to test whether their soft X-ray excess emission in the 0.2–0.5 keV band as reported by Kaastra et al. (2003) maintains after application of current knowledge of the XMM-Newton background and calibration. In this context, we examine the recent claim (Bregman et al., 2006) that the XMM-Newton sub...
