The Molecular Kennicutt-Schmidt Law in Arp 240 on Sub-kpc Scales

13 December 2024 Star formation has long been known to be associated with molecular gas, with higher (surface) densities of molecular gas generally correlating with higher (surface) densities of star formation. Galaxy interactions and mergers are known to have globally enhanced star formation but it has been a matter of debate if star formation and molecular gas are correlated in the same way as…
