Resolving the Multiple Component Outflows in PG 1211+143: II. The Soft X-ray View of the Ultra Fast Outflow
James Reeves, Valentina Braito, Misaki Mizumoto +16
The nearby quasar, PG 1211+143, has one of the prototype examples of an ultra fast outflow (UFO), as seen in several past XMM-Newton and Chandra observations. In December 2024, PG…
The dynamic central environment of NGC 3516 revealed by XRISM
Anna JuráÅová, 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…
Resolving the Multiple Component Outflows in PG 1211+143: I. The Fe-K Absorption Structure and UFO Forest
Misaki Mizumoto, James N. Reeves, Valentina Braito +15
We present the initial high-resolution X-ray spectroscopic observations of the Fe-K absorption structure in the luminous nearby quasar PG 1211+143, utilizing the X-ray Imaging and…
Unraveling the structure of the stratified ultra-fast outflows in PDS 456 with XRISM
Yerong Xu, Luigi C. Gallo, Kouichi Hagino +18
Multiple clumpy wind components () in the luminous quasar PDS 456 have recently been resolved by XRISM in the Fe-K band for the first time. In this paper, we i…
A possible two-fold scenario for the disc-corona of the luminous AGN 1H 0419--577: a high-density disc or a warm corona
Delphine Porquet, James N. Reeves, Valentina Braito
[abridged] 1H 0419-577 is a highly-accreting, luminous BLS1 AGN. This study aims to characterise its disc-corona system using, for the first time, simultaneous XMM-Newton and NuSTA…
