XRISM Resolves the Circum-nuclear Environment of NGC 4945

Peter G. Boorman, Poshak Gandhi, Yoshihiro Ueda +31

Compton-thick Active Galactic Nuclei (AGN) represent one of the most elusive phases of massive black hole growth, yet are expected to contribute substantially to the Cosmic X-ray B…

Fe K line from the Broad Line Region of PDS456 with XRISM/Resolve

Alfredo Luminari, Fabrizio Nicastro, Stefano Bianchi +1

Using XRISM’s Resolve microcalorimeter, the authors detect a neutral Fe Kα emission line from the broad line region of the quasar PDS 456, measuring a modest blueshift, narrow widt…

First detection of ultra-fast outflows in a quiescent galaxy

Yerong Xu, Malgorzata Siudek, Victor Rodríguez Morales +7

Outflows in active galactic nuclei (AGN) are recognized as a fundamental mechanism driving the co-evolution of supermassive black holes (SMBHs) and their host galaxies. Although po…

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…

Multi-wavelength observations of a jet launch in real time from the post-changing-look Active Galaxy 1ES 1927+654

Sibasish Laha, Eileen T. Meyer, Dev R. Sadaula +34

We present results from a high cadence multi-wavelength observational campaign of the enigmatic changing look AGN 1ES 1927+654 from May 2022- April 2024, coincident with an unprece…
