The DIRECD Coronal Mass Ejection Direction Catalog: Three-dimensional Propagation Inferred from Coronal Dimmings

open access: yesThe Astrophysical Journal Supplement Series
Coronal mass ejections (CMEs) are among the primary drivers of space weather disturbances at Earth, yet their early propagation in the low corona remains poorly constrained owing to occultation and projection effects inherent to coronagraph observations.

Signatures of localised particle acceleration at a global coronal shock wave

open access: yesAstronomy & Astrophysics
Context. Extreme ultraviolet (EUV) waves are global waves in the solar corona that accelerate particles. The efficiency of this acceleration depends on local plasma characteristics such as the Alfvén speed and the geometry of the magnetic field.

Galaxies Lighting Up: Discovery of Seventy New Turn-on Changing-look Active Galactic Nuclei

open access: yesThe Astrophysical Journal
“Changing-look active galactic nuclei” (CL AGN) show dramatic, rapid changes in optical/UV continuum and broad-line emission. The majority of CL AGN have been found dimming as “turn-off” CL AGN because most selection methods start from samples of ...

FAS-XAI: Fuzzy and Explainable AI for Interpretable Vetting of Kepler Exoplanet Candidates

open access: yesMathematics
The detection of exoplanets in space-based photometry relies on identifying periodic transit signatures in stellar light curves. The Kepler Threshold Crossing Events (TCE) catalog collects all periodic dimming signals detected by the pipeline, while the ...

Multi‐Model Simulation of Solar Geoengineering Indicates Avoidable Destabilization of the West Antarctic Ice Sheet

open access: yesEarth's Future
Heat transported in Circumpolar Deep Water is driving the break‐up of ice shelves in the Amundsen Sea sector of Antarctica, that has been simulated to be unavoidable under all plausible greenhouse gas scenarios.
