XMM - Newton observations of the diffuse X - ray emission in the starburst galaxy NGC 253 ⋆
Aims. We present a study of the diffuse X-ray emission in the halo and the disc of the starburst galaxy NGC 253. Methods. After removing point-like sources, we analysed XMM-Newton images, hardness ratio maps and spectra from several regions in the halo and the disc. We introduce a method to produce vignetting corrected images from the EPIC pn data, and we developed a procedure that allows a cor...
متن کاملAn XMM - Newton view of M 101 - III . Diffuse X - ray emission
We present a study of the X-ray properties of the nearby face-on Scd spiral galaxy M101 based on recent XMM-Newton observations. In this third and final paper in the present series, we focus on the spatial and spectral properties of the residual emission, after excluding bright X-ray sources with L X > 10 37 erg s −1. Within a central region of radius 10 ′ (21 kpc), the X-ray emission broadly t...
متن کاملXmm - Newton Observations of the Diffuse X - ray Background
We analyzed two XMM-Newton observations in the direction of the high density, high latitude, neutral hydrogen cloud MBM20 and of a nearby low density region that we called the Eridanus hole. The cloud MBM20 is at a distance evaluated between 100 and 200 pc from the Sun and its density is sufficiently high to shield about 75% of the foreground emission in the 3/4 keV energy band. The combination...
متن کاملDetection 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...
متن کاملXMM-Newton Observation of Solar Wind Charge Exchange Emission
We present an XMM-Newton spectrum of diffuse X-ray emission from within the solar system. The spectrum is dominated by probable C VI lines at 0.37 keV and 0.46 keV, an O VII line at 0.56 keV, O VIII lines at 0.65 keV and ∼ 0.8 keV, Ne IX lines at ∼ 0.92 keV, and Mg XI lines at ∼ 1.35 keV. This spectrum is consistent with that expected from charge exchange emission between the highly ionized sol...
