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 emission…

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…

Delving into the depths of NGC 3783 with XRISM. I. Kinematic and ionization structure of the highly ionized outflows

Missagh Mehdipour, Jelle S. Kaastra, Megan E. Eckart +17

We present our study of the XRISM observation of the Seyfert-1 galaxy NGC 3783. XRISM's Resolve microcalorimeter has enabled, for the first time, a detailed characterization of the…

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)…
