Exploring the host galaxy of the most distant lensed quassar at z=6.51
Abstract
We present IRAM/NOEMA, JCMT/SCUBA-2 and JVLA observations of the most distant known lensed quasar J0439+1634 at z = 6.51. We report the detections of dust emission, [CII], [CI], CO(6--5), CO(7--6), CO(9--8), CO(10--9) lines and water vapor emissions in the interstellar medium of its host galaxy. The strong gravitational lensing makes J0439+1634 be the far-infrared (FIR) brightest quasar at z > 6, with a gravitationally-amplified FIR luminosity of 3.5*10^13 L_sun and the brightest [CII] line (f_peak = 40mJy) ever detected at z > 6. These observations allow us to constrain the excitation model, dust emission model, molecular gas mass, dust mass and dynamical mass.
