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…

Excitation of molecular hydrogen by cosmic-ray protons

Marco Padovani, Daniele Galli, Corey T. Plowman +4

Low-energy cosmic rays ( GeV) are responsible for the ionisation and heating of molecular clouds. While the role of supra-thermal electrons produced in the ionisation…

Counterpart identification and classification for eRASS1 and characterisation of the AGN content

M. Salvato, J. Wolf, T. Dwelly +44

[abridged] Accurately accounting for the AGN phase in galaxy evolution requires a large, clean AGN sample. This is now possible with SRG/eROSITA. The public Data Release 1 (DR1, Ja…

On the acceleration of cosmic rays at the post-adiabatic shocks of supernova remnants

O. Petruk, R. Bandiera, T. Kuzyo +2

When a supernova remnant (SNR) interacts with the dense material of an interstellar cloud, its shock wave decelerates rapidly, and the post-shock temperature drops to levels that p…

High-resolution Radio Study of Pulsar Wind Nebula MSH 15-52 and Supernova Remnant RCW 89

S. Zhang, C. -Y. Ng, N. Bucciantini

We present high-resolution radio observations of the pulsar wind nebula (PWN) MSH15-52, which is renowned for its distinctive hand-like shape, and its associated supernova remnant…
