A XRISM view of the iron line complex in NGC 1068: Rethinking the prototypical Compton-thick AGN

S. Bianchi, B. Vander Meulen, E. Bertola +32

We analyze a XRISM/Resolve observation of NGC1068, focusing on the Fe K and Fe K fluorescent lines and on the Fe XXV and Fe XXVI emission complexes. Line centroid energies,…

X-ray stellar feedback in low-metallicity starbursts: Insights from the template starburst galaxy ESO 338-IG04 and its halo

M. Chatzis, L. M. Oskinova, S. Reyero Serantes +7

The X-ray output of low-metallicity starburst galaxies is a key component of stellar feedback, tracing the processes responsible for gas ionization and chemical enrichment. The int…

Discovery of crested quasi-periodic eruptions following the most luminous SRG/eROSITA tidal disruption event

Pietro Baldini, Arne Rau, Andrea Merloni +11

We report the discovery of complex flaring activity from the galactic nucleus hosting the five-year-old tidal disruption event eRASSt J234402.9-352640 (J2344). With Einstein Probe…

A supermassive black hole under the radar: Repeating X-ray variability in a Seyfert galaxy

Matteo Imbrogno, Andrea Sacchi, Giovanni Miniutti +4

In the last few years, a few supermassive black holes (SMBHs) have shown short-term (of the order of hours) X-ray variability. Given the limited size of the sample, every new addit…

Lost and Found - A gallery of overlooked optical nuclear transients from the ZTF archive

E. Quintin, E. Russeil, M. Llamas Lanza +12

Tidal disruption events (TDEs) correspond to the destruction of a star by the tidal forces around a black hole, leading to outbursts which can last from months to years. These tran…

Radio properties of the quasi-periodic eruption source RXJ1301.9+2747 at parsec scales

S. D. von Fellenberg, R. Arcodia, P. Benke +6

Quasi-periodic eruptions (QPEs) are repeating soft X-ray flares associated with galactic nuclei. Several recent works have found evidence that the accretion flow in the galactic nu…
