Variability of the X-ray obscuring wind in Mrk 335 with XMM-Newton/RGS

Daniele Rogantini, Erin Kara, Luigi Gallo +10

Transient X-ray obscuration in Seyfert 1 galaxies likely arises from clumpy accretion-disk winds near the broad-line region (BLR), but the wind structure and short-timescale variab…

The transient event in NGC 1566 from 2017 to 2019 -- I. An eccentric accretion disk and a turbulent, disk-dominated broad-line region unveiled by double-peaked Ca II and O I lines

M. W. Ochmann, W. Kollatschny, M. A. Probst +12

NGC 1566 is known for exhibiting recurrent outbursts, which are accompanied by changes in spectral type. The most recent transient event occurred from 2017 to 2019 and was reported…
