Harnessing the XMM-Newton data
Listed in IVOA Registry (Virtual Observatory)
The XMM-Newton X-ray observatory has played a prominent role in astrophysics, conducting precise and thorough observations of the X-ray sky for the past two decades.
Description
The most recent iteration of the XMM-Newton catalogue, 4XMM, and one of its latest data releases, DR11, mark significant improvements over previous XMM-Newton catalogues, serving as a cornerstone for comprehending the diverse inhabitants of the X-ray sky. In this investigation, we employ X-ray detections and spectra extracted from the 4XMM-DR11 catalogue, subjecting them to fitting procedures using simple models.
Our study operates within the framework of the XMM2ATHENA project, which focuses on developing state-of-the-art methods that exploit existing XMM-Newton data. In this study, we introduce and publicly release four catalogues containing measurements derived from X-ray spectral modelling of sources. The first catalogue encompasses outcomes obtained by fitting an absorbed power-law model to all the extracted spectra for individual detections within the 4XMM-DR11 dataset.

The second catalogue presents results obtained by fitting both an absorbed power-law and an absorbed black-body model to all unique physical sources listed in the 4XMM-DR11s catalogue, which documents source detection results from overlapping XMM-Newton observations. For the third catalogue we use the five band count rates derived from the pipe line detection of X-ray sources to mimic low resolution spectra to get a rough estimate of the spectral shape (absorbed power law) of all 4XMM-DR11 detections.
In the fourth catalogue, we conducted spectral analyses for the subset of identified sources with extracted spectra, employing various models based on their classification into categories such as AGNs, stars, XRBs, and CVs. Finally, the scientific potential of these catalogues is highlighted by discussing the capabilities of optical and mid-infrared colours for selecting absorbed AGNs.
