Very High Energy Gamma-Rays from Binary Systems [PDF]

open access: yes, 2010
This thesis presents a study of the very high energy (VHE) gamma-ray emission from X-ray binary systems using the H.E.S.S. imaging atmospheric Cherenkov array.

Transitional Dynamics: Unveiling the Coexistence and Interplay of Type B and Type C Quasiperiodic Oscillations in MAXI J1348-630

open access: yesThe Astrophysical Journal
Based on broadband timing analysis of Insight-HXMT and Neutron Star Interior Composition Explorer data from the 2019 outburst of the black hole X-ray binary MAXI J1348-630, we report the detection of the coexistence and competitive interplay between Type

Field Report from Collaborative Research Center 1625: Heterogeneous Research Data Management Using Ontology Representations

open access: yesAdvanced Engineering Materials, EarlyView.
A unified research data management framework for heterogeneous materials data is presented. The system integrates multimodal datasets using ontologies and knowledge graphs, enabling interoperability and FAIR (findable, accessible, interoperable, reusable) data principles. By linking data across scales and workflows, it supports reproducible, Artifitial

ON THE NATURE OF HARD X-RAY EXTRAGALACTIC SOURCES OBSERVED WITH XMM-NEWTON [PDF]

open access: yes, 2012
Over the last decade, X-ray surveys have provided outstanding new results due to the lack of the common selection effects present at other wavelengths.

Multiepoch Observations of the Nearby Spiral Galaxy NGC 3938 with the Chandra X-Ray Observatory

open access: yesThe Astronomical Journal
We present an analysis of two epochs of ACIS observations of the SA(s)c spiral galaxy NGC 3938 with the Chandra X-ray Observatory. The total exposure time of the observations was 95 ks, with a limiting unabsorbed luminosity of ≈10 ^38 erg s ^−1 assuming ...

Towards Defect Phase Diagrams: From Research Data Management to Automated Workflows

open access: yesAdvanced Engineering Materials, EarlyView.
A research data management infrastructure is presented for the systematic integration of heterogeneous experimental and simulation data required for defect phase diagrams. The approach combines openBIS with a companion application for large‐object storage, automated metadata extraction, provenance tracking and federated data access, thereby supporting ...

Streaking and splashing: design of a grazing incidence x-ray streak camera and time-resolved measurements of the structure of water [PDF]

open access: yes, 2006
The performance of cesium iodide photocathodes has been characterized for use with grazing incidence soft x-rays. The total electron yield and pulsed quantum efficiency has been measured in a reflection geometry as a function of photon energy (100 eV to ...

On the Nature of Einstein Probe Transient EP250916a: Insights from X-Ray, Optical, and Radio Observations

open access: yesThe Astrophysical Journal
We report multiwavelength studies of the transient EP250916a, detected by the Einstein Probe on 2025 September 16. Located at low Galactic latitude, the source exhibited a rapid X-ray brightening, reaching an unabsorbed 0.5–10 keV flux of (6.4 ± 0.1 ...
