Harnessing the XMM-Newton data: X-ray spectral modelling of 4XMM-DR11 detections and 4XMM-DR11s sources

A. Viitanen, G. Mountrichas, H. Stiele +13

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. The most recen…

The link among X-ray spectral properties, AGN structure and the host galaxy

G. Mountrichas, A. Viitanen, F. J. Carrera +5

In this work, we compare the SMBH and host galaxy properties of X-ray obscured and unobscured AGN. For that purpose, we use X-ray detected AGN in the 4XMM-DR11 catalo…

A journey from the hard to the soft state: How do QPOs evolve in the 2021 outburst of GX 339-4?

H. Stiele, A. K. H. Kong

We investigated the snapshots of five NICER observations of the black hole transient GX 339-4 when the source transited from the hard state into the soft state during its outburst…

XMM2ATHENA, the H2020 project to improve XMM-Newton analysis software and prepare for Athena

Natalie A. Webb, Francisco J. Carrera, Axel Schwope +31

XMM-Newton, a European Space Agency observatory, has been observing the X-ray, ultra-violet and optical sky for 23 years. During this time, astronomy has evolved from mainly studyi…
