XMM - Newton survey of the Local Group galaxy M 33 ⋆
In an XMM-Newton raster observation of the bright Local Group spiral galaxy M 33 we study the population of X-ray sources (X-ray binaries, supernova remnants) down to a 0.2–4.5 keV luminosity of 10 35 erg s −1 – more than a factor of 10 deeper than earlier ROSAT observations. EPIC hardness ratios and optical and radio information are used to distinguish between different source classes. The sur...
متن کاملXMM - Newton survey of M 31 ⋆ , ⋆ ⋆
In an analysis of XMM-Newton archival observations of the bright Local Group spiral galaxy M 31 we study the population of X-ray sources (X-ray binaries, supernova remnants) down to a 0.2–4.5 keV luminosity of 4.4×10 34 erg s −1. EPIC hardness ratios and optical and radio information are used to distinguish between different source classes. The survey detects in an area of 1.24 square degree 85...
متن کاملAn XMM - Newton observation of the galaxy group MKW 4
We present an X–ray study of the galaxy group or poor cluster MKW 4. Working with XMMNewton data we examine the distribution and properties of the hot gas which makes up the group halo. The inner halo shows some signs of structure, with circular or elliptical β models providing a poor fit to the surface brightness profile. This may be evidence of large scale motion in the inner halo, but we do ...
متن کاملThe XMM-Newton-MSSL survey of Polars
The XMM-Newton-MSSL survey of polars is a snapshot survey of nearly 40 polars. We present the initial results, with an emphasis on the energy balance in these systems and the number of systems which were observed in a low accretion state. In contrast to the ROSAT results we find that the vast majority of polars show no ‘soft X-ray excess’. We find that half of our sample were observed in low or...
متن کاملMolecular and atomic gas in the Local Group galaxy M 33
We present high resolution large scale observations of the molecular and atomic gas in the Local Group Galaxy M33. The observations were carried out using the HEterodyne Receiver Array (HERA) at the 30m IRAM telescope in the CO(2–1) line achieving a resolution of 12×2.6 km s−1, enabling individual Giant Molecular Clouds (GMCs) to be resolved. The observed region is 650 square arcminutes mainly ...
