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…
A Two-Component Probability Distribution Function Describes the mid-IR Emission from the Disks of Star-Forming Galaxies
Debosmita Pathak, Adam K. Leroy, Todd A. Thompson +28
High-resolution JWST-MIRI images of nearby spiral galaxies reveal emission with complex substructures that trace dust heated both by massive young stars and the diffuse interstella…
Star Formation Efficiency in Nearby Galaxies Revealed with a New CO-to-H2 Conversion Factor Prescription
Yu-Hsuan Teng, I-Da Chiang, Karin M. Sandstrom +24
Determining how galactic environment, especially the high gas densities and complex dynamics in bar-fed galaxy centers, alters the star formation efficiency (SFE) of molecular gas…
VLT-MUSE spectroscopy of AGNs misclassified by BPT diagnostic or with weak emission lines
Christopher J. Agostino, Samir Salim, Médéric Boquien +3
Despite powerful X-ray emission, some AGNs are known to either lack optical emission lines (so-called 'optically dull' AGNs) or have lines that fall on the star-forming branch of t…
Molecular and Ionized Gas in Tidal Dwarf Galaxies: The Spatially Resolved Star-Formation Relation
Navyasree Kovakkuni, Federico Lelli, Pierre-alain Duc +12
Tidal dwarf galaxies (TDGs) are low-mass objects that form within tidal and/or collisional debris ejected from more massive interacting galaxies. We use CO() observations from…
X-ray luminosity-star formation rate scaling relation: Constraints from the eROSITA Final Equatorial Depth Survey (eFEDS)
G. Riccio, G. Yang, Małek +7
We present measurements of the relation between X-ray luminosity and star formation activity for a sample of normal galaxies spanning the redshift range between 0 and 0.25. We use…
