Illuminating the past 8 billion years of cold gas towards two gravitationally lensed quasars

Abstract:

Using the Boolardy Engineering Test Array of the Australian Square Kilometre Array Pathfinder (ASKAP BETA), we have carried out the first z = 0–1 survey for H I and OH absorption towards the gravitationally lensed quasars PKS B1830−211 and MG J0414+0534. Although we detected all previously reported intervening systems towards PKS B1830−211, in the case of MG J0414+0534, three systems were not found, indicating that the original identifications may have been confused with radio frequency inter...
