Chemical enrichment of the Perseus cluster core seen by XRISM/Resolve

XRISM Collaboration, Marc Audard, Hisamitsu Awaki +143

The intracluster medium (ICM) is rich in chemical elements, produced by core-collapse (SNcc) and Type Ia supernovae (SNIa) over the last 12 Gyr. Whereas cluster outskirts are…

A Fast, Hot Wind from a Nuclear Starburst

XRISM Collaboration, Marc Audard, Hisamitsu Awaki +137

Galaxies with intense star formation often host multiphase, galaxy-scale winds powered by supernovae and fast stellar winds. These are strong enough to disrupt the star-forming int…

A XRISM/Resolve view of the dynamics in the hot gaseous atmosphere of M87

XRISM Collaboration, M. Audard, H. Awaki +138

The XRISM/Resolve microcalorimeter directly measured the gas velocities in the core of the Virgo Cluster, the closest example of AGN feedback in a cluster. This proximity allows us…

Comparing XRISM cluster velocity dispersions with predictions from cosmological simulations: are feedback models too ejective?

XRISM Collaboration, Marc Audard, Hisamitsu Awaki +147

The dynamics of the intra-cluster medium (ICM), the hot plasma that fills galaxy clusters, are shaped by gravity-driven cluster mergers and feedback from supermassive black holes (…

BASS XXVIII: Near-infrared Data Release 2, High-Ionization and Broad Lines in Active Galactic Nuclei

Jakob den Brok, Michael J. Koss, Benny Trakhtenbrot +20

We present the BAT AGN Spectroscopic Survey (BASS) Near-infrared Data Release 2 (DR2), a study of 168 nearby ( = 0.04, < 0.6) active galactic nuclei (AGN) from the all-…

BAT AGN Spectroscopic Survey -- XIX: Type 1 versus Type 2 AGN dichotomy from the point of view of ionized outflows

A. F. Rojas, E. Sani, I. Gavignaud +18

We present a detailed study of ionized outflows in a large sample of ~650 hard X-ray detected AGN. Using optical spectroscopy from the BAT AGN Spectroscopic Survey (BASS) we are ab…

Space Telescope and Optical Reverberation Mapping Project. VIII. Time Variability of Emission and Absorption in NGC 5548 Based on Modeling the Ultraviolet Spectrum

G. A. Kriss, G. De Rosa, J. Ely +164

We model the ultraviolet spectra of the Seyfert 1 galaxy NGC~5548 obtained with the Hubble Space Telescope during the 6-month reverberation-mapping campaign in 2014. Our model of t…
