Observation of A Solar Like Magnetic Reconnection Event in an AGN Corona with XRISM
Gal Vardi, Ehud Behar, Liyi Gu +14
The authors present the first direct observation of a magnetic reconnection flare in the X‑ray corona of the active galaxy NGC 3783, using XRISM and XMM‑Newton data that reveal a N…
The emergence of X-ray emission lines during relativistic radio-jet formation in the changing-look active galactic nucleus 1ES 1927+654
Dev R. Sadaula, Sibasish Laha, Eileen T. Meyer +27
We present results from a comprehensive multi-wavelength monitoring campaign of the changing-look active galactic nucleus 1ES 1927+654 during the onset and evolution of a relativis…
Reverberation in the Narrow Fe K Line in the Seyfert Galaxy NGC 4151 with XRISM
Jon M. Miller, Aberahmen Zoghbi, Xin Xiang +11
Emission lines that "echo" variations in the ionizing flux produced close to black holes are powerful probes of the central engine. In the Seyfert-1.5 galaxy NGC 4151, high-resolut…
Chemical enrichment of the Perseus cluster core seen by XRISM/Resolve
XRISM Collaboration, Marc Audard, Hisamitsu Awaki +147
The intracluster medium (ICM) is rich in chemical elements, produced by core-collapse (SNcc) and Type Ia supernovae (SNIa) over the last 12 Gyr. Whereas cluster outskirts are…
Discovery of ultra-fast outflows with v in local bright active galactic nuclei
Laura Borrelli, Matteo Guainazzi, Giorgio Lanzuisi +5
Ultra-fast outflows (UFOs) are mildly relativistic (outflow velocity ) nuclear winds detected as blueshifted absorption lines from highly ionized, dense gas in the X-…
Delving into the depths of NGC 3783 with XRISM: V. Broad-band modeling of ionized outflows
Keqin Zhao, Jelle S. Kaastra, Liyi Gu +7
The Seyfert 1 galaxy NGC 3783 hosts a multiphase warm absorber (WA) that has been extensively studied in the X-ray band. High-resolution spectra from 2000-2001 revealed a complex o…
