Diagnosing the Fe line complex of the intracluster medium by XRISM high-resolution spectroscopy
K. Fukushima, L. Hirata, N. Y. Yamasaki +17
We aim to test the validity of the CIE framework in the ICM by performing line diagnostics based mainly on resolved Fe-K emission lines. Methods. We analyse Resolve full-array spec…
The Nineteenth Data Release of the Sloan Digital Sky Survey
SDSS Collaboration, Gautham Adamane Pallathadka, Mojgan Aghakhanloo +210
Mapping the local and distant Universe is key to our understanding of it. For decades, the Sloan Digital Sky Survey (SDSS) has made a concerted effort to map millions of celestial…
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.…
Exploring chemical enrichment of the intracluster medium with the Line Emission Mapper
François Mernier, Yuanyuan Su, Maxim Markevitch +27
Synthesized in the cores of stars and supernovae, most metals disperse over cosmic scales and are ultimately deposited well outside the gravitational potential of their host galaxi…
X-ray metal line emission from the hot circumgalactic medium: probing the effects of supermassive black hole feedback
Nhut Truong, Annalisa Pillepich, Dylan Nelson +15
We derive predictions from state-of-the-art cosmological galaxy simulations for the spatial distribution of the hot circumgalactic medium (CGM, ) through its…
The 2023 release of Cloudy
Marios Chatzikos, Stefano Bianchi, Francesco Camilloni +8
We describe the 2023 release of the spectral synthesis code Cloudy. Since the previous major release, migrations of our online services motivated us to adopt git as our version con…
Mapping the imprints of stellar and AGN feedback in the circumgalactic medium with X-ray microcalorimeters
Gerrit Schellenberger, Ákos Bogdán, John A. ZuHone +24
The Astro2020 Decadal Survey has identified the mapping of the circumgalactic medium (CGM, gaseous plasma around galaxies) as a key objective. We explore the prospects for characte…
Resonant scattering of the OVII X-ray emission line in the circumgalactic medium of TNG50 galaxies
Dylan Nelson, Chris Byrohl, Anna Ogorzalek +15
We study the impact of resonantly scattered X-ray line emission on the observability of the hot circumgalactic medium (CGM) of galaxies. We apply a Monte Carlo radiative transfer p…
Gas sloshing and cold fronts in pre-merging galaxy cluster Abell 98
Arnab Sarkar, Scott Randall, Yuanyuan Su +10
We present deep Chandra observations of the pre-merger galaxy cluster Abell 98. Abell 98 is a complex merging system. While the northern (A98N) and central subclusters (A98S) are m…
Discovery of a pre-merger shock in an intercluster filament in Abell 98
Arnab Sarkar, Scott Randall, Yuanyuan Su +11
We report the first unambiguous detection of an axial merger shock in the early-stage merging cluster Abell 98 using deep (227 ks) Chandra observations. The shock is about 420 kpc…
Mean Occupation Function of High Redshift Quasars from the Planck Cluster Catalog
Priyanka Chakraborty, Suchetana Chatterjee, Alankar Dutta +1
We characterise the distribution of quasars within dark matter halos using a direct measurement technique for the first time at redshifts as high as . Using the Planck Su…
