High-statistics simulations of NewAthena WFI background using Geant4

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

The observation of hot gas structures is one science goal of the Wide Field Imager (WFI) on ESA's NewAthena X-ray observatory. Because the measurement of these faint diffuse source…

Resolving the temporal evolution of M87 jet with -arcsec Chandra observations

Camille Poitras, Gerrit Schellenberger, Ralph Kraft +3

We present a 13-year Chandra/HRC-I study of the M87 jet, using point-spread-function deconvolution to achieve unprecedented sub-arcsecond X-ray resolution of its kiloparsec-scale s…

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.…

Towards efficient machine-learning-based reduction of the cosmic-ray induced background in X-ray imaging detectors: increasing context awareness

Artem Poliszczuk, Dan Wilkins, Steven W. Allen +15

Traditional cosmic ray filtering algorithms used in X-ray imaging detectors aboard space telescopes perform event reconstruction based on the properties of activated pixels above a…

Augmenting astronomical X-ray detectors with AI for enhanced sensitivity and reduced background

D. R. Wilkins, A. Poliszczuk, B. Schneider +13

Bringing artificial intelligence (AI) alongside next-generation X-ray imaging detectors, including CCDs and DEPFET sensors, enhances their sensitivity to achieve many of the flagsh…
