Early postural dynamics reveal the rapid processing of fake social cues for deceptive actions in sports

Iris Güldenpenning, Lars Schulze Frielinghaus, Nils Tobias Böer, Thomas Schmidt et autres

Deceptive actions such as head fakes are a hallmark of interactive sports, yet it is not well understood how decisions and whole-body responses to head fakes unfold over time. In the present study, participants viewed video sequences of a basketball player passing …

Research opportunities with MaQuIS - updates and continuation of a dedicated consortium

Bart Root, Lisa Wörner, Matthias Weigelt

Mars was long thought to be in a quiescent state with minimal geodynamic processes taking place at present. However, NASA's InSight mission shed light on the planet's present-day tectonic activity, part of which is likely related to mantle plumes and associated magmatic …

Stellar tidal streams around nearby spiral galaxies with deep imaging from amateur telescopes

M. Stein, J. D. Sakowska, Matthias Weigelt, Javier Román et autres

Context. Tidal interactions between massive galaxies and their satellites are fundamental processes in a universe with a Λ cold dark matter (ΛCDM) cosmology, and they redistribute material into faint features that preserve records of past galactic interactions. While stellar streams in the …

Impact of Deployable Solar Panels on Gravity Field Recovery in GRACE-like Satellites: a Closed-Loop Simulation Study

Andreas Leipner, Alexey Kupriyanov, Arthur Reis, Annike Knabe et autres

Abstract Future satellite gravimetry missions must meet increasing scientific demands, requiring advanced technologies, e.g., novel inertial sensors, laser ranging systems and potentially electric thrusters to operate in a drag-free regime. Deployable solar panels offer a promising solution by providing sufficient power even …

Evaluation of Deployable Solar Panels on GRACE-like Satellites by Closed-Loop Simulations

Andreas Leipner, Alexey Kupriyanov, Arthur Reis, Annike Knabe et autres

Future satellite gravimetry missions seek to surpass the performance of CHAMP, GOCE, GRACE, and GRACE-FO to meet increasing scientific and operational demands. These missions will integrate advanced technologies, including optical and quantum accelerometers, high-precision inter-satellite laser ranging, and micro-Newton electric thrusters. However, …

CARIOQA Pathfinder Mission Development towards Future Quantum Space Gravimetry Missions

Nina Fletling, Annike Knabe, Jürgen Müller, Manuel Schilling et autres

For over two decades, satellite gravimetry missions have been measuring the Earth’s gravity field globally providing valuable observations for geosciences. Successor missions are already in development to extend this time series. Future objectives include achieving higher spatial and temporal resolutions of gravity …

Kalman filter framework for a regional mass change model from GRACE satellite gravity

Viviana Wöhnke, Annette Eicker, Matthias Weigelt, Marvin Reich et autres

Abstract In this study a regional modelling framework for water mass changes is developed. The approach can introduce geodetic observation types of varying temporal and spatial resolution including their correlated error information. For this purpose a Kalman filter process was set up …
