The Accretion Explorer Interferometer (AEI) Phase I NASA Innovative Advanced Concepts Final Report
Kimberly A. Weaver, Jenna M. Cann, Kenneth Carpenter +30
We must create superb X-ray images to understand the detailed physical processes behind some of the most powerful astronomical objects. The need to achieve this capability has been…
X-ray grating spectroscopy as a mission enhancement
Hans Moritz Guenther, Ehud Behar, Joel N. Bregman +27
We propose to add instruments to any potential future X-ray mission with focussing optics that is considered in NASA's ASTRA framework. Such an instrument is a necessity to study A…
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…
High-resolution X-ray spectroscopy with XRISM/Resolve reveals super-Solar abundance ratios in Virgo/M87
J. Martin, A. Simionescu, F. Mernier +26
The chemical composition of the intracluster medium (ICM) provides key insights into the enrichment history of galaxy clusters. However, high-resolution abundance measurements with…
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…
