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…
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 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…
Population synthesis of Galactic middle-aged pulsar wind nebulae II. Observational signatures of superefficiency
D. F. Torres, A. De Sarkar, B. Olmi +2
Pulsar wind nebulae (PWNe) interacting with the host supernova remnants (SNRs) can enter the reverberation phase in which reverse-shock-driven compression amplifies the magnetic fi…
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…
Metallicity Gradients in Modern Cosmological Simulations II: The Role of Bursty Versus Smooth Feedback at High-Redshift
Alex M. Garcia, Paul Torrey, Aniket Bhagwat +22
The distribution of gas-phase metals within galaxies encodes the impact of stellar feedback on galactic evolution. At high-redshift, when galaxies are rapidly assembling, feedback-…
