Atlas of High Resolution X-ray spectra: a Diagnostic Tool of the Hot Universe
Abstract
We present an Atlas of High Resolution X-ray spectra obtained with the Reflection Grating Spectrometer, RGS, on-board XMM-Newton. All the public RGS1 and RGS2 exposures have been analysed in order to identify those containing useful data and classified according to some pre-defined quality criteria. We found that out of 18000 RGS1&RGS2 exposures, about 4300 are useful, of which 220/2300 provide very-good/good quality spectra. The spectra are grouped according target Simbad Object Class. The spectra are plotted and information is provided about important properties point-like or extended emission and presence or absence of emission lines and line identification if applicable. The Atlas clearly shows differences when comparing different object classes, but not only that, differences are also found among different objects in an individual class and even among different spectra of an individual object. Spectral properties that characterize the different object classes as well as their variability properties are discussed.
