The Array Control and Data Acquisition software of the Cherenkov Telescope Array Observatory

I. Oya, B. López, P. Aubert +61

The Cherenkov Telescope Array Observatory (CTAO) aims to advance knowledge of the gamma-ray sky as the largest gamma-ray observatory ever built. The CTAO will be deployed at two si…

The WISSHFUL program: the highest redshift UFO discovered in a non-lensed QSO

G. Lanzuisi, L. Borrelli, E. Piconcelli +28

We present the first results from the WISSHFUL program, an XMM-Newton heritage program targeting luminous QSOs at Cosmic Noon. We report on recent simultaneous XMM-Newton and NuSTA…

Is XRISM/Resolve probing a "raining" absorber in Mrk 509?

M. Dadina, V. Missaglia, V. Braito +19

X-ray spectroscopy of AGN offers unique insights into the reprocessing of radiationand gas dynamics near SMBH. The Sey 1 galaxy Mrk 509 is an ideal laboratory for these studies sin…

XMM/HST monitoring of the ultra-soft highly accreting Narrow Line Seyfert 1 RBS 1332

R. Middei, S. Barnier, F. G. Saturni +10

Ultra-soft narrow line Seyfert 1 (US-NLSy) are a poorly observed class of active galactic nuclei characterized by significant flux changes and an extreme soft X-ray excess. This pe…

Coordinated X-ray and UV absorption within the accretion disk wind of the active galactic nucleus PG 1126-041

M. Giustini, P. Rodríguez Hidalgo, J. N. Reeves +14

Accretion disk winds launched close to supermassive black holes (SMBHs) are a viable mechanism to provide feedback between the SMBH and the host galaxy. We aim to characterize the…

Transient obscuration event captured in NGC 3227 IV. Origin of the obscuring cloud variability

S. Grafton-Waters, J. Mao, M. Mehdipour +13

Obscuration events in type I active galactic nuclei (AGN) have been detected more frequently in recent years. The strong flux decrease in the soft X-ray band between observations h…
