Molecular gas in type 2 quasars at z~0.2-0.3
Abstract
We present results of CO(1-0) spectroscopic observations of 10 SDSS type 2 quasars (QSO2) at z~0.2-0.3 observed with the 30m IRAM radiotelescope and the Australia Telescope Compact Array. We report 5 new confirmed CO(1-0) detections and 1 tentative detection. They have L'(CO)~several x 1e9 K km s-1 pc2, while upper limits for the non detections are L'(CO)<~ several x 1e9 K km s-1 pc2. This study increases the total number of QSO2 with CO measurements at z<~1 to 20, with a 50% detection rate.
