XRISM finds the Changing-Look AGN NGC 1365 in an extended low state: A dense, highly ionized outflow obscures the central source
Fatima Zaidouni, Erin Kara, Peter Kosec +21
We present the first XRISM/Resolve observations of the active galactic nucleus, NGC 1365, obtained in 2024 February and July. NGC 1365 is known for rapid transitions between Compto…
Investigating the complex absorbers of Mrk 766 with XMM-Newton
T. Matamoro Zatarain, E. Costantini, A. JuráÅová +1
Aims. We examine the high energy resolution X-ray spectrum of the narrow-line Seyfert 1 galaxy Mrk 766 using 4 observations taken with XMM-Newton in 2005, to investigate the proper…
A failed wind candidate in NGC 3783 from the 2001 year campaign with Chandra/HETGS
Chen Li, Jelle S. Kaastra, Liyi Gu +4
We reanalyze the Chandra/HETGS observations of NGC 3783 from the campaign in the year 2001, identifying significant spectral variations in the Fe unresolved transition array (UTA)…
The outflowing ionised gas of I Zw 1 observed by HST COS
A. JuráÅová, E. Costantini, G. A. Kriss +8
We present an analysis of the HST COS spectrum of IZw1 aiming to probe the absorbing medium associated with the active galactic nucleus (AGN). We fitted the emission spectrum and p…
