CoRGI in MaNGA - II. NGC 5717: cold-gas accretion and disk growth in a BGG

Damir Gasymov, Ivan Yu. Katkov, Eva K. Grebel +6

Large-scale stellar counter-rotation, in which two coplanar stellar components rotate in opposite directions, is usually interpreted as a signature of external gas accretion. Such…

There is no single density: star-forming regions and galaxies hold more dense ionized gas than long assumed

J. Eduardo Méndez-Delgado, Christophe Morisset, William J. Henney +29

Ionized gas fills star-forming regions and galaxies, and nearly everything we know about its temperature, pressure, mass, and composition is inferred from its emission lines [1-3].…

The Nineteenth Data Release of the Sloan Digital Sky Survey

SDSS Collaboration, Gautham Adamane Pallathadka, Mojgan Aghakhanloo +210

Mapping the local and distant Universe is key to our understanding of it. For decades, the Sloan Digital Sky Survey (SDSS) has made a concerted effort to map millions of celestial…
