Recurrent Novae — A Review

open access: yesActa Polytechnica CTU Proceedings, 2015
In recent years, recurrent nova eruptions are often observed very intensely in wide range of wavelengths from radio to optical to X-rays. Here I present selected highlights from recent multi-wavelength observations. The enigma of T Pyx is at the heart of

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

open access: yesThe 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

Fracture processes studied in CRESST

open access: yesNuclear Instruments and Methods in Physics Research Section A: Accelerators, Spectrometers, Detectors and Associated Equipment, 2006
In the early stages of running of the CRESST dark matter search with sapphire crystals as detectors, an unexpectedly high rate of signal pulses appeared. Their origin was finally traced to fracture events in the sapphire due to the very tight clamping of the detectors.

Discrimination, Harassment, and Bias in Higher Education: Disaggregating the Experiences of LGBTQ+ Students

open access: yesNew Directions for Higher Education, Volume 2025, Issue 210, Page 37-46, Summer 2025.
ABSTRACT Queer and transgender students in higher education experience elevated rates of discrimination, bias, and harassment, which affect their well‐being and academic outcomes. These experiences differ across various identities within these communities, necessitating a nuanced approach to understanding their distinct challenges.

The 66-channel SQUID readout system for CRESST II

open access: yes, 2002
The upgrade of the CRESST experiment to a 10 kg target of phonon/light detectors necessitates the installation of 66 readout channels in the CRESST cryostat.

DoubleTES detectors to investigate the CRESST low energy background: results from above-ground prototypes

open access: yesEuropean Physical Journal C: Particles and Fields
In recent times, the sensitivity of low-mass direct dark matter searches has been limited by unknown low energy backgrounds close to the energy threshold of the experiments known as the low energy excess (LEE).

The CRESST dark matter search

open access: yesNuclear Physics B - Proceedings Supplements, 2000
Abstract We present the current status of CRESST (Cryogenic Rare Event Search using Superconducting Thermometers) project and new results concerning detector development. The basic technique involved is to search for WIMPs by the measurement of non-thermal phonons, as created by WIMP-induced nuclear recoils.

Rapid growth of a carbonate island over the last millennium

open access: yesSedimentology, Volume 71, Issue 7, Page 2119-2143, December 2024.
Abstract Low‐lying islands in tropical regions are vulnerable to near‐term sea‐level rise and hurricane‐induced flooding, with substantial human impact. These risks motivate researchers to elucidate the processes and timescales involved in the formation, growth and stabilization of coastlines through the study of Holocene shoreline dynamics.

Search for low-mass Dark Matter with the CRESST Experiment

open access: yes, 2018
CRESST is a multi-stage experiment directly searching for dark matter (DM) using cryogenic $\mathrm{CaWO_4}$ crystals. Previous stages established leading limits for the spin-independent DM-nucleon cross section down to DM-particle masses $m_\mathrm{DM}$

A Low‐Viscosity Lower Lunar Mantle Implied by Measured Monthly and Yearly Tides

open access: yesAGU Advances, Volume 5, Issue 5, October 2024.
Abstract The Moon's frequency‐dependent tidal response, expressed as temporal variations in its gravity field through the Love number k2 ${k}_{2}$ and as dissipation through the quality factor Q $Q$, provides information about its interior structure. Lunar laser ranging has provided measurements for Q $Q$, but so far no frequency‐dependent values for ...
