Molecular Gas and Atomic Carbon in IRAS F10214+4724

摘要：

Using the IRAM 30m telescope and the Plateau de Bure interferometer we have detected the C1(3p2 -3pl) and CO 3-2, 4-3, 6-5, 7-6 transitions towards the distant luminous IR galaxy IRAS F10214+4724 at z = 2.286. The source is spatially resolved by our CI(3P2 3pl) observation and we detect a velocity gradient along the east-west direction. The C I line ratio allows us to derive a carbon excitation temperature of 42+12-9K. The rest-frame 360 μm dust continuum morphology is more compact than the line emitting region which supports previous findings that the FIR luminosity arises from regions closer to the AGN.
