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…
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…
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…
Delving into the depths of NGC 3783 with XRISM IV. Mapping of the accretion flow with Fe K emission lines
Chen Li, Jelle S. Kaastra, Liyi Gu +18
Using XRISM/Resolve time-averaged spectra of the well-known Seyfert-1.5 active galactic nucleus (AGN) in NGC 3783, we investigate the nature of the Fe K emissio…
Delving into the depths of NGC 3783 with XRISM III. Birth of an ultrafast outflow during a soft flare
Liyi Gu, Keigo Fukumura, Jelle Kaastra +18
The 2024 X-ray/UV observation campaign of NGC 3783, led by XRISM, revealed the launch of an ultrafast outflow (UFO) with a radial velocity of 0.19c (57000 km/s). This event is sync…
Density constraint of the warm absorber in NGC 5548
Keqin Zhao, Jelle S. Kaastra, Liyi Gu
Context. Ionized outflows in active galactic nuclei (AGNs) are thought to influence the evolution of their host galaxies and super-massive black holes (SMBHs). Distance is importan…
