Abstract:Previous studies have shown significant differences in the enhancement of the star-formation rate (SFR) and the star-formation efficiency (SFE = SFR/M mol ) between spiral-spiral and spiral-elliptical mergers. In order to shed light on the physical mechanism of these differences, we present NOEMA observations of the molecular gas distribution and kinematics (linear resolutions of ∼ 2 kpc) in two representative close major-merger starforming pairs: the spiral-elliptical pair Arp 142 and the spiral-spiral pair A… Show more
