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…
Connecting galaxies with their haloes -- from parsec to Mpc scales
K. Fahrion, J. van de Sande, K. R. Akhil +12
Galaxy evolution is driven by processes occurring across a wide range of scales, from star formation within giant molecular clouds (parsec scales) to outflows and secular evolution…
Signatures of star formation inside galactic outflows
Dily Duan Yi Ong, Francesco D'Eugenio, Roberto Maiolino +13
Observations have suggested that galactic outflows contain substantial amounts of dense and clumpy molecular gas, creating favourable conditions for igniting star formation. Indeed…
Resolved HII regions in NGC 253: Ionized gas structure and suggestions of a universal density-surface brightness relation
Rebecca L. McClain, Adam K. Leroy, Enrico Congiu +23
We use the full-disk VLT-MUSE mosaic of NGC 253 to identify 2492 HII regions and study their resolved structure. With an average physical resolution of 17 pc, this is one of the la…
