Reigniting the FUSE II: O VI Emission in Massive Elliptical Galaxies
Michael Reefe, Michael McDonald, Greg L. Bryan +6
This is the second paper in a series where we examine archival far-ultraviolet spectroscopy of 29 massive elliptical galaxies from the Far Ultraviolet Spectroscopic Explorer (FUSE)…
XRISM reveals sloshing-driven gas motions in the core of Abell 2029
Yuusuke Uchida, Yuna Saito, Naomi Ota +13
We investigate the velocity structure of the intracluster medium (ICM) in the core of the relaxed cool-core cluster Abell 2029 using XRISM Resolve spectroscopy. We analyze combined…
XRISM Reveals a Kinematically Coherent Core System of the Nearby Cool-Core Cluster Abell 2199
Kazunori Suda, Kyoko Matsushita, Kosuke Sato +14
We present the results of a deep 251 ks XRISM/Resolve observation of the cool core of the galaxy cluster Abell 2199. From the integrated spectrum of the central Reso…
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…
Cross Calibration of Galaxy Cluster Temperatures Measured with NuSTAR, XMM-Newton, and Chandra
Fiona Lopez, Daniel R. Wik, Cicely Potter +10
The use of galaxy clusters to constrain cosmology is limited in part due to uncertainties in derived cluster masses, which often depend on the gas temperature. Unfortunately, there…
The intracluster light analysis of the most evolved systems of galaxies: fossil groups
Nícolas O. L. de Oliveira, Yolanda Jiménez-Teja, Renato A. Dupke +7
We present the analysis of the intracluster light (ICL) in three fossil groups (FG), RXJ085640.72+055347.36, RX J1136+0713, and RX J1410+4145, at z ~ 0.1. We used two optical broad…
Constraints on Non-Thermal Pressure at galaxy cluster outskirts from a Joint SPT and XMM-Newton Analysis
Arnab Sarkar, Michael McDonald, Lindsey Bleem +11
We present joint South Pole Telescope (SPT) and XMM-Newton observations of 8 massive galaxy clusters (0.8--1.710 M) spanning a redshift range of 0.16 to 0.…
Unveiling the Cosmic Chemistry II: "Direct" -based metallicity of galaxies at 3 10 with JWST/NIRSpec
Priyanka Chakraborty, Arnab Sarkar, Randall Smith +10
We report the detection of the [O III] auroral line in 42 galaxies within the redshift range of . These galaxies were selected from publicly available JWST data release…
Unveiling the Cosmic Chemistry: Revisiting the Mass-Metallicity Relation with JWST/NIRSpec at 4 < z < 10
Arnab Sarkar, Priyanka Chakraborty, Mark Vogelsberger +12
We present star formation rates (SFR), the mass-metallicity relation (MZR), and the SFR-dependent MZR across redshifts 4 to 10 using 81 star-forming galaxies observed by the JWST N…
Temperature Structure in the Perseus Cluster Core Observed with Hitomi
Hitomi Collaboration, Felix Aharonian, Hiroki Akamatsu +192
The present paper investigates the temperature structure of the X-ray emitting plasma in the core of the Perseus cluster using the 1.8--20.0 keV data obtained with the Soft X-ray S…
Simulating Astro-H Observations of Sloshing Gas Motions in the Cores of Galaxy Clusters
J. ZuHone, E. Miller, A. Simionescu +1
Astro-H will be the first X-ray observatory to employ a high-resolution microcalorimeter, capable of measuring the shift and width of individual spectral lines to the precision nec…
ASTRO-H White Paper - Clusters of Galaxies and Related Science
T. Kitayama, M. Bautz, M. Markevitch +22
The next generation X-ray observatory ASTRO-H will open up a new dimension in the study of galaxy clusters by achieving for the first time the spectral resolution required to measu…
Robust Quantification of Galaxy Cluster Morphology Using Asymmetry and Central Concentration
D. Nurgaliev, M. McDonald, B. A. Benson +3
We present a novel quantitative scheme of cluster classification based on the morphological properties that are manifested in X-ray images. We use a conventional radial surface bri…
Detection of a Rare Supersoft Outburst Event during a Suzaku Observation of 1E0102.2-7219
D. Takei, M. Tsujimoto, S. Kitamoto +4
We report the detection of a transient X-ray source toward the Small Magellanic Cloud (SMC) using the X-ray Imaging Spectrometer (XIS) onboard the Suzaku telescope. The source was…
