The rise and decline of a transient obscuration event in a moderately distant type-I quasar
A. Akylas, A. Georgakakis, E. Pouliasis +5
Outflows of ionised material, often dubbed warm absorbers (WAs), are common in nearby Seyferts but sparse in distant and more energetic quasars (QSOs). We present multi-epoch X-ray…
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…
STONKS: Quasi-real time XMM-Newton transient detection system
E. Quintin, N. A. Webb, I. Georgantopoulos +6
Over recent decades, astronomy has entered the era of massive data and real-time surveys. This is improving the study of transient objects - although they still contain some of the…
