An X-Ray View of the Cataclysmic Variable V902 Mon: Discovery of an X-Ray Eclipse

open access: yesThe Astrophysical Journal
V902 Mon is one of a few eclipsing intermediate polars (IPs) and shows deep eclipses in the optical lightcurves. The presence of a strong Fe K α fluorescence line in its X-ray spectrum and its low X-ray flux compared to other IPs suggests significant ...

Improved He-like Kα Line Diagnostics for Photoionized Plasmas

open access: yesThe Astrophysical Journal
The helium-like K α line complexes are valuable diagnostics of the electron density, temperature, and ionization conditions of astrophysical plasmas. The ratios of these lines can be altered by the presence of lithium-like ions through both inner-shell ...

Untersuchung von Untergrundprozessen im CRESST Experiment

open access: yes, 2014
The major objectives of the work described in this dissertation were to gain a better understanding of the backgrounds in the CRESST experiment and to study how to reduce them from their present levels.

OxRop : data analysis software for CRESST-II

open access: yes, 2007
Dark matter forms the dominant contribution to the matter density of the universe, and a host of experiments aim to detect the favoured dark matter e candidate, the Weakly Interacting Massive Particle (WIMP).

Untersuchung des neutroneninduzierten Untergrundes im Dunklen Materie Experiment CRESST

open access: yes, 2007
CRESST searches for WIMPs (Weakly Interacting Massive Particles) as candidates for dark matter in the universe using low temperature detectors. The use of light-phonon detector in the second phase of CRESST, which enables discrimination between electron ...
