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…
Polycyclic aromatic hydrocarbons destruction in star-forming regions across 42 nearby galaxies
Oleg V. Egorov, Adam K. Leroy, Karin Sandstrom +30
Polycyclic aromatic hydrocarbons (PAHs) are widespread in the interstellar medium (ISM) of Solar metallicity galaxies, where they play a critical role in ISM heating, cooling, and…
The Lyman-alpha Halos of Galaxies at z=2-3 in the Keck Baryonic Structure Survey
Ryan F. Trainor, Noah R. Lamb, Charles C. Steidel +5
We present the large-scale spatial Lya profiles of galaxies from the Keck Baryonic Structure Survey (KBSS) at 2<z<3. This work also describes the Lya imaging for the KBSS-Lya surve…
Where is the Supervirial hot gas? I: A pilot study with sightlines to Galactic X-ray binaries
Armando Lara-DI, Yair Krongold, Smita Mathur +4
Hot, \logT\ 7.5, gas was recently discovered in the Milky Way in extragalactic sightlines. In order to determine its location, here we present sightlines to Galactic X-ray b…
