Dark-matter search with CRESST

Czechoslovak Journal of Physics, 2006
The CRESST experiment is looking for non-baryonic particle dark matter via nuclear scattering in CaWO4. The simultaneous measurement of the heat and the scintillation light generated by an event in a CaWO4 single crystal is used to discriminate between electron and nuclear recoils thanks to their different light output.

Description of CRESST-II data

, 2017
In Phase 2 of CRESST-II 18 detector modules were operated for about two years (July 2013 - August 2015). Together with this document we are publishing data from two detector modules which have been used for direct dark-matter searches. With these data-sets we were able to set world-leading limits on the cross section for spin-independent elastic ...

Detector Development for the CRESST Experiment

Journal of Low Temperature Physics
AbstractRecently low-mass dark matter direct searches have been hindered by a low-energy background, drastically reducing the physics reach of the experiments. In the CRESST-III experiment, this signal is characterised by a significant increase of events below 200 eV. As the origin of this background is still unknown, it became necessary to develop new

The Sun as a sub-GeV Dark Matter Accelerator [PDF]

, 2018
Sub-GeV halo dark matter that enters the Sun can potentially scatter off hot solar nuclei and be ejected much faster than its incoming velocity. We derive an expression for the rate and velocity distribution of these reflected particles taking into ...

Sensemaking of Process Data from Evaluation Studies of Educational Games: An Application of Cross‐Classified Item Response Theory Modeling

Journal of Educational Measurement, Volume 63, Issue 1, Spring 2026.
Abstract Process information collected from educational games can illuminate how students approach interactive tasks, complementing assessment outcomes routinely examined in evaluation studies. However, the two sources of information are historically analyzed and interpreted separately, and diagnostic process information is often underused.

The Complex X-Ray Obscuration Environment in the Radio-loud Type 2 Quasar 3C 223

The Astrophysical Journal, 2023
3C 223 is a radio-loud, Type 2 quasar at z = 0.1365 with an intriguing X-ray Multi-mirror Mission (XMM)-Newton spectrum that implicated it as a rare, Compton-thick ( N _H ≳ 1.25 × 10 ^24 cm ^−2 ) active galactic nucleus (AGN). We obtained contemporaneous

Impure Thoughts on Inelastic Dark Matter

, 2010
The inelastic dark matter scenario was proposed to reconcile the DAMA annual modulation with null results from other experiments. In this scenario, WIMPs scatter into an excited state, split from the ground state by an energy delta comparable to the ...

Radiation Transport Through the Martian Atmosphere as a Function of the Zenith Angle

Journal of Geophysical Research: Planets, Volume 130, Issue 12, December 2025.
Abstract The topographic influence of the radiation environment on the Martian surface radiation is crucial for future human exploration. Topographic maps help assess radiation flux variations, aiding in hazard evaluation. Creating a global radiation map requires accounting for seasonally varying atmospheric density, heliospheric modulation, and ...
