Mapping dark matter in the Bullet Cluster using JWST imaging and spectroscopy

Gregor Rihtaršič, Maruša Bradač, Guillaume Desprez +23

We present an updated gravitational lens model of the Bullet cluster (1E 0657-56) by combining JWST NIRCam imaging and NIRSpec spectroscopy. Although previous lens models relied on…

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

XRISM Collaboration, Marc Audard, Hisamitsu Awaki +147

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…

Inferring the mass of the circumgalactic medium using X-ray resonant scattering

Nhut Truong, Maxim Markevitch, Dylan Nelson +1

The circumgalactic medium (CGM) regulates galaxy growth and retains the imprint of feedback from supernovae and supermassive black holes. However, the bulk of the hot CGM produces…

Accurate Determination of Chemical Abundances near a Supermassive Black Hole

The XRISM collaboration

The metal abundances in galactic nuclei carry key information on the history of star formation and mass transfer in central regions of galaxies. X-ray fluorescence analysis is a un…

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…

High Spectral Resolution X-ray Observations of the Evolved Supermassive Stellar Binary System Carinae - Iron K Band Profile Revealed with XRISM

XRISM Collaboration, Marc Audard, Hisamitsu Awaki +138

The supermassive binary system, Carinae, is experiencing enormous wind-driven mass loss at a rate unparalleled in the rest of the Galaxy. Their wind-wind collision (WWC) conti…
