Dissecting the Nuclear Structure of NGC 5548 with XRISM. I. Physical Properties of the Highly Ionized Outflows

Missagh Mehdipour, Jon M. Miller, Jelle S. Kaastra +21

We present a detailed spectral analysis of an X-Ray Imaging and Spectroscopy Mission (XRISM) observation of the prototypical Seyfert 1 galaxy NGC 5548. XRISM's Resolve microcalorim…

The dynamic central environment of NGC 3516 revealed by XRISM

Anna Juráňová, Erin Kara, Ehud Behar +15

We present a detailed, time-resolved analysis of the Fe K band of the Seyfert 1.5 galaxy NGC 3516 observed with XRISM. The 249 ks observation spanning 310 ks in elapsed time…

A systematic study of the ultra-fast outflow responses to luminosity variations in active galactic nuclei

Yerong Xu, Ciro Pinto, Daniele Rogantini +7

The extreme velocities and high ionization states of ultra-fast outflows (UFOs) make them a promising candidate for AGN feedback on the evolution of the host galaxy. However, their…

Study of the optical to X-ray broad emission lines of Mrk 110

A. Juráňová, E. Costantini, L. Di Gesu +7

In order to shed light on the characteristics of the broad line region (BLR) in a narrow-line Seyfert 1 galaxy, we present an analysis of X-ray, UV, and optical spectroscopic obser…

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…

Detection of an Unidentified Soft X-ray Emission Feature in NGC 5548

Liyi Gu, Junjie Mao, Jelle S. Kaastra +17

NGC~5548 is an X-ray bright Seyfert 1 active galaxy. It exhibits a variety of spectroscopic features in the soft X-ray band, including in particular the absorption by the AGN outfl…
