SADCat: A Catalog of Supra-Arcade Downflow Events in Solar Flares

Trestan F. Simon, Ryan J. French

Supra-arcade downflows (SADs) are sunward-traveling features routinely observed in hot fan structures above magnetic loop arcades during eruptive solar flares. We manually compiled…

Multiphase images of a powerful supernova-driven wind in the early Universe

Rebecca L. Davies, D. B. Fisher, R. Herrera-Camus +38

Galactic winds are considered a likely driver of rapid quenching in early massive galaxies, but until now there has been no direct evidence that such systems drive winds powerful e…

Toward Unbreaking the Universe: MINERVA Measurements of Color Gradients in Massive Quiescent Galaxies Can Help Ease Too-Early Star Formation Tensions

Sam E. Cutler, Luke Robbins, Danilo Marchesini +41

The discovery of a population of massive, ancient quiescent galaxies within the first 2 Gyr of the Universe's history has led to significant tensions with models of galaxy formatio…

Investigating Pre-flare Signatures in Spectroscopic Observations of an X9-class Solar Flare

Louis Seyfritz, Maria Kazachenko, Ryan French

On October 3rd, 2024, the Sun emitted an X9.0-class flare from active region NOAA 13842. The event was recorded by multiple space-based instruments, beginning hours before the erup…

Full-polarization millimeter wavelength variability of Sagittarius A* during the 2018 EHT campaign

Ezequiel Albentosa-Ruiz, Jasmin E. Washington, Nicola Marchili +272

Sagittarius A* (Srg A*), the supermassive black hole at the center of the Milky Way, provides a unique laboratory to study accretion dynamics and plasma processes near the event ho…

Empirical flare energy limits for the largest historical sunspots

N. A. Krivova, T. Chatzistergos, M. Kazachenko +1

Extreme solar particle events reveal that the Sun can occasionally produce eruptions significantly more energetic than those observed in the modern era. These events are thought to…
