The PHANGS-Hα survey. Ground-based narrow-band imaging of nearby star-forming galaxies
Alessandro Razza, Guillermo A. Blanc, Brent Groves +36
We present PHANGS-Hα, a narrow-band imaging survey that maps Hα emission over a sample of 65 nearby massive star-forming galaxies. The data were obtained using the MPG-ESO 2.2-mete…
The lifetime of 100,000 molecular clouds in the nearby Universe
Z. Bazzi, M. I. N. Kobayashi, D. Colombo +25
Multiple mechanisms are proposed for the formation of giant molecular clouds (GMCs), from gravitational free-fall caused by self-gravity to stellar feedback-driven gas compression.…
Constraining the Sub-Galactic Relationship Between Star Formation and the Hot Interstellar Medium in NGC 4254
Erik B. Monson, Bret D. Lehmer, Amirnezam Amiri +17
We investigate the relationship between star formation and X-ray emission from the hot interstellar medium (ISM) on kpc scales in NGC 4254 (M99) by combining spatially resolv…
Evolved Supergiants in PHANGS I: Red Supergiants in 19 Galaxies between 5-20 Mpc with HST and JWST
Sumit K. Sarbadhicary, David Thilker, Adam K. Leroy +17
Red supergiants (RSGs) are important for our understanding of supernova progenitors, stellar populations, stellar evolution, mass loss and dust production. Extragalactic surveys of…
PHANGS-JWST: the largest extragalactic molecular cloud catalog traced by polycyclic aromatic hydrocarbon emission
Z. Bazzi, D. Colombo, F. Bigiel +25
High-resolution JWST images of nearby spiral galaxies reveal polycyclic aromatic hydrocarbon (PAH) emission structures that trace molecular gas, including CO-dark regions. We ident…
Characterization of Two Cool Galaxy Outflow Candidates Using Mid-Infrared Emission from Polycyclic Aromatic Hydrocarbons
Jessica Sutter, Karin Sandstrom, Ryan Chown +22
We characterize two candidate cool galactic outflows in two relatively low mass, highly inclined Virgo cluster galaxies: NGC4424 and NGC4694. Previous analyses of observations usin…
