The PHANGS-AstroSat Atlas of Nearby Star Forming Galaxies

Hamid Hassani, Erik Rosolowsky, Eric W. Koch +29

We present the Physics at High Angular resolution in Nearby GalaxieS (PHANGS)-AstroSat atlas, which contains ultraviolet imaging of 31 nearby star-forming galaxies captured by the…

Stellar associations powering HII regions $\unicode{x2013}$ II. Escape fraction of ionizing photons

Fabian Scheuermann, Kathryn Kreckel, Jia Wei Teh +27

Newly formed stars have a profound impact on their environment by depositing energy and momentum into the surrounding gas. However, only a fraction of the stellar feedback is retai…

A nuclear disc at Cosmic Noon: evidence of early bar-driven galaxy evolution

Zoe A. Le Conte, Dimitri A. Gadotti, Thomas Harvey +7

Recent studies have revealed that bars can form as early as a few billion years after the Big Bang, already displaying characteristics similar to those of evolved bars in the Local…

Molecular gas and star formation in central rings across nearby galaxies

Damian R. Gleis, Sophia K. Stuber, Eva Schinnerer +20

Nearby galaxies exhibit a variety of structures, including central rings, similar to the MW Central Molecular Zone (CMZ). These rings are common in barred galaxies and can be gas-r…

Bar ages derived for the first time in nearby galaxies: Insights on secular evolution from the TIMER sample

Camila de Sá-Freitas, Dimitri A. Gadotti, Francesca Fragkoudi +9

Once galaxies settle their discs and become self-gravitating, stellar bars can form, driving the subsequent evolution of their host galaxy. Determining the ages of bars can therefo…

Duration and properties of the embedded phase of star formation in 37 nearby galaxies from PHANGS-JWST

Lise Ramambason, Mélanie Chevance, Jaeyeon Kim +32

Light reprocessed by dust grains emitting in the infrared allows the study of the physics at play in dusty, embedded regions, where ultraviolet and optical wavelengths are attenuat…
