DIGging into HII regions: the role of ionizing photon leakage and spectral hardening in coupling HII regions and diffuse ionized gas
Dalya Baron, Kathryn Kreckel, Gwen C. Rudie +15
The optical emission-line ratios of star-forming galaxies are broadly understood in the framework of photoionization, yet some systematic trends remain unexplained. Using 50--100 p…

Do spiral arms enhance star formation efficiency?
Miguel Querejeta, Adam K. Leroy, Sharon E. Meidt +32
Spiral arms are some of the most spectacular features in disc galaxies, and also present in our own Milky Way. It has been argued that star formation should proceed more efficientl…

Analyzing resolved stellar populations across the disk of a galaxy can provide unique insights into how that galaxy assembled its stellar mass over its lifetime. Previous work at ~…
Quantifying the energetics of molecular superbubbles in PHANGS galaxies
E. J. Watkins, K. Kreckel, B. Groves +26
Star formation and stellar feedback are interlinked processes that redistribute energy and matter throughout galaxies. When young, massive stars form in spatially clustered environ…
The PHANGS-MUSE Nebula Catalogue
B. Groves, K. Kreckel, F. Santoro +17
Ionized nebulae provide critical insights into the conditions of the interstellar medium (ISM). Their bright emission lines enable the measurement of physical properties, such as t…
