Upper limits to the water abundance in starburst galaxies*
Abstract
Aims.We have searched for emission from the 557 GHz ortho-water line in the interstellar medium of six nearby starburst galaxies. Methods.We used the Odin satellite to observe the transition of o-H2O in the galaxies NGC 253, IC 342, M 82, NGC 4258, CenA, and M 51. None of the galaxies in our sample was detected. Results.We derive three sigma upper limits to the H2O abundance relative to H2 ranging from 210-9 to 110-8. The best of these upper …
