High-statistics simulations of NewAthena WFI background using Geant4

Matthew K. Heine, Catherine E. Grant, Marshall W. Bautz +14

The paper presents high‑statistics Geant4 simulations of the background caused by cosmic‑ray interactions in the Wide Field Imager of ESA's NewAthena X‑ray observatory, using both…

XRISM Observations of Abell 1795: Evidence for Low Turbulence and Resonant Scattering

Arnab Sarkar, Eric D. Miller, Brian McNamara +10

We present high-resolution X-ray spectroscopic observations of the cool-core galaxy cluster Abell~1795 obtained with XRISM/Resolve. The cluster was observed with two deep pointings…

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…

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.…

Using the XMM-Newton small window mode to investigate systematic uncertainties in the particle background of X-ray charge-coupled device detectors

Gerrit Schellenberger, Ralph Kraft, Paul Nulsen +17

The level and uncertainty of the particle induced background in CCD detectors plays a crucial role for future X-ray instruments, such as the Wide Field Imager (WFI) onboard Athena.…

Focal Plane of the Arcus Probe X-Ray Spectrograph

Catherine E. Grant, Marshall W. Bautz, Eric D. Miller +7

The Arcus Probe mission concept provides high-resolution soft X-ray and UV spectroscopy to reveal feedback-driven structure and evolution throughout the universe with an agile resp…
