Research explores gas and dust interactions in galaxies, indicating ways to understand star formation.
Key Points
This research aims to examine the relationships between different phases of the interstellar medium and galaxy properties, particularly focusing on molecular gas.
Analyzed CO maps covering at least 70% of the optical extent for 121 late-type galaxies.
Determined global molecular gas mass (MH2) based on CO mapping.
Investigated scaling relations between MH2, star formation rate (SFR), and stellar mass (M⋆).
Examined correlations between ISM components and mid- and far-infrared luminosities.
Correlations between MH2 and SFR, and M⋆ show large scatter due to quenching effects.
Total gas mass has the closest association with dust mass.
Molecular gas also correlates well with dust when using map-based MH2 estimates.
Mid- and far-infrared luminosities can serve as proxies for molecular gas in cases lacking observations.
