On the Kennicutt-Schmidt scaling law of submillimetre galaxies

Popis výsledku v původním jazyce

We aim at determining the K-S law parameters for the first time for a well-selected, statistical sample of SMGs. We used the Atacama Large Millimetre/submillimetre Array (ALMA) to conduct a high resolution (0 ''.2), 870 mu m continuum imaging survey of 40 SMGs, which were initially selected at 1.1 mm in the COSMOS field. We analysed a sample of 32 out of the 40 target SMGs, for which our new ALMA 870 mu m data provide information about the spatial extent of dust emission, and all of which have dust-obscured SFR and dust-based gas mass estimates available from our previous study. We divided our sample into equally large subsamples of main-sequence (MS) objects and starbursts (factor of >3 above the MS), and found their K-S relations to be of the form Sigma(SFR) proportional to Sigma(0.81 +/- 0.01)(gas) and Sigma(SFR) proportional to Sigma(0.84 +/- 0.39)(gas), respectively. n
