Imaging the Molecular Gas in a Z=3.9 Quasar Host Galaxy at 0.3 Resolution: a Central, Sub-kiloparsec Scale Star Formation Reservoir in Apm08279+5255


We have mapped the molecular gas content in the host galaxy of the strongly lensed high redshift quasar APM08279+5255 (z = 3.911) with the Very Large Array at 0.3 resolution. The CO(J=1→0) emission is clearly resolved in our maps. The CO(J=1→0) line luminosity derived from these maps is in good agreement with a previous single-dish measurement. In contrast… (More)
