Closing the Gap between Observed Low-Mass Galaxy HI Kinematics and CDM Predictions
Amy Sardone, Annika H. G. Peter, Alyson M. Brooks +1
Testing the standard cosmological model (CDM) at small scales is challenging. Galaxies that inhabit low-mass dark matter halos provide an ideal test bed for dark matter models b…

Star Formation Laws and Efficiencies across 80 Nearby Galaxies
Jiayi Sun, Adam K. Leroy, Eve C. Ostriker +37
We measure empirical relationships between the local star formation rate (SFR) and properties of the star-forming molecular gas on 1.5 kpc scales across 80 nearby galaxies. These r…
Kpc-scale properties of dust temperature in terms of dust mass and star formation activity
