Witnessing the rapid growth of disk galaxies over cosmic time using JWST and HST
Samane Raji, Mireia Montes, Ignacio Trujillo +3
Measuring galaxy sizes is fundamental to understanding how galaxies grow and evolve. Traditional methods to measure sizes either trace the concentration of light (i.e., effective r…
Magnetoacoustic Shocks and Spectropolarimetric Signals in He I 10830 Ã
Hirdesh Kumar, Tobias Felipe, Christoph Kuckein +2
Umbral flashes are manifestations of magnetoacoustic shocks in the solar chromosphere. These phenomena are thought to influence the evolution of chromospheric umbral magnetic field…
Infrared spectropolarimetry of a C-class solar flare footpoint plasma -- I. Spectral features and forward modelling
Z. Vashalomidze, C. Quintero Noda, T. V. Zaqarashvili +10
We performed high-spatial resolution spectropolarimetric observations of active region NOAA 13363 during a C-class flare with the Gregor Infrared Spectrograph (GRIS) on 16 July 202…
Automatic detection of CMEs using synthetically-trained Mask R-CNN
Francisco A. Iglesias, Diego G. Lloveras, Florencia L. Cisterna +6
Coronal mass ejections (CMEs) are a major driver of space weather. To assess CME geoeffectiveness, among other scientific goals, it is necessary to reliably identify and characteri…
