Status of the CRESST Dark Matter Search [PDF]

AIP Conference Proceedings, 2009
The CRESST experiment aims for a detection of dark matter in the form of WIMPs. These particles are expected to scatter elastically off the nuclei of a target material, thereby depositing energy on the recoiling nucleus.

The CRESST Experiment: Recent Results and Prospects [PDF]

AIP Conference Proceedings, 2000
The CRESST experiment seeks hypothetical WIMP particles that could account for the bulk of dark matter in the Universe. The detectors are cryogenic calorimeters in which WIMPs would scatter elastically on nuclei, releasing phonons. The first phase of the

Influence of Magnetic Fields on Precipitating Solar Wind Hydrogen at Mars. [PDF]

Geophys Res Lett, 2022
Abstract Solar wind protons can interact directly with the hydrogen corona of Mars through charge exchange, resulting in energetic neutral atoms (ENAs) able to penetrate deep into the upper atmosphere of Mars. ENAs can undergo multiple charge changing interactions, leading to an observable beam of penetrating protons in the upper atmosphere. We seek to

A Statistical Investigation of Factors Influencing the Magnetotail Twist at Mars. [PDF]

Geophys Res Lett, 2022
Abstract The Martian magnetotail exhibits a highly twisted configuration, shifting in response to changes in polarity of the interplanetary magnetic field's (IMF) dawn‐dusk (BY) component. Here, we analyze ∼6000 MAVEN orbits to quantify the degree of magnetotail twisting (θTwist) and assess variations as a function of (a) strong planetary crustal field

The CRESST II Dark Matter Search [PDF]

Journal of Physics: Conference Series, 2012
Direct Dark Matter detection with cryodetectors is briefly discussed, with particular mention of the possibility of the identification of the recoil nucleus.

Towards an automated data cleaning with deep learning in CRESST. [PDF]

Eur Phys J Plus, 2023
AbstractThe CRESST experiment employs cryogenic calorimeters for the sensitive measurement of nuclear recoils induced by dark matter particles. The recorded signals need to undergo a careful cleaning process to avoid wrongly reconstructed recoil energies caused by pile-up and read-out artefacts.

Environmental Changes Recorded in Sedimentary Rocks in the Clay-Sulfate Transition Region in Gale Crater, Mars: Results From the Sample Analysis at Mars-Evolved Gas Analysis Instrument Onboard the Mars Science Laboratory Curiosity Rover. [PDF]

J Geophys Res Planets
Abstract The Curiosity rover explored the region between the orbitally defined phyllosilicate‐bearing Glen Torridon trough and the overlying layered sulfate‐bearing unit, called the “clay‐sulfate transition region.” Samples were drilled from the top of the fluviolacustrine Glasgow member of the Carolyn Shoemaker formation (CSf) to the eolian Contigo ...

Cosmic activation of Cresst’s CaWO₄ crystals

Journal of Physics: Conference Series, 2021
Abstract The CRESST experiment searches for dark matter induced nuclear recoils inside CaWO4 based cryogenic calorimeters at the Laboratori Nazionali del Gran Sasso (LNGS) in Italy. To identify reliably a potential signal, a precise understanding of its background budget is crucial. An important background category could be “cosmogenics”:

Surprising Decrease in the Martian He Bulge During PEDE‐2018 and Changes in Upper Atmospheric Circulation

Journal of Geophysical Research: Planets, Volume 128, Issue 8, August 2023., 2023
Abstract Using the Neutral Gas and Ion Mass Spectrometer (NGIMS) on the Mars Atmosphere Volatile and Evolution spacecraft (MAVEN), we analyzed data from Mars Year (MY) 32, 34, and 35 to examine the He bulge during the northern winter solstice (Ls ∼ 180–240), specifically focusing on the effects from the planet encircling dust event (PEDE‐2018).
