Multiwavelength study of supernova remnants in the Circinus constellation with SRG/eROSITA
A. Khokhriakova, W. Becker
The paper combines optical, radio, and eROSITA X‑ray data to search for and characterize supernova remnant candidates in the Circinus constellation, identifying several new candida…
A study of the large-scale formation in the environment of A3266: Infalling groups, filaments, and a premerger cold front
J. Dietl, A. Veronica, T. H. Reiprich +7
The paper uses eROSITA X‑ray data to map the outskirts of the galaxy cluster Abell 3266, revealing a hot X‑ray filament linking the cluster to a nearby group and showing how the cl…
The X-ray catalogue of FGK stars within 10 pc: The coronal temperature-brightness relation explained with the RTV scaling law
M. M. Bennedik, B. Stelzer, M. Caramazza +3
The authors compile an X‑ray catalog of FGK main‑sequence stars within 10 pc, derive coronal temperatures and X‑ray fluxes from eROSITA, XMM‑Newton and ROSAT data, and show that th…
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…
Towards a joint X-ray and gamma-ray analysis of Pulsar Wind Nebulae with Gammapy
Katharina Egg, Alison M. W. Mitchell
The paper describes how the authors adapt eROSITA X-ray data and H.E.S.S. gamma-ray data for joint analysis of pulsar wind nebulae using the Gammapy Python package.
When X-ray Features Fail to Identify Intrinsic Emitters: Label Noise and Luminosity Overlap in Machine Learning Classification of AGN and Star-forming Galaxies
Jaymin Ding
The paper shows that adding X‑ray flux as a feature to a Random Forest classifier of AGN and star‑forming galaxies reduces accuracy because the X‑ray luminosities of the two classe…
