Fig. 2


Left panel: 12CO(2−1) intensity map obtained with the IRAM PdBI toward AGN.1317. The color wedge of the intensity map is in Jy beam-1 km s-1. The black cross marks the coordinates of the phase tracking centre of our observations (see Table 1). The rms noise level is σ = 0.07 Jy beam-1 km s-1 and contour levels run from 3σ to 7σ with 1σ spacing. In this map a velocity range of ~360 km s-1 is used. The beam of 473 × 233 (PA = 147°) is plotted at lower left. Right panel: 12CO(2−1) integrated spectrum obtained with the IRAM PdBI toward AGN.1317 centred on the optical velocity of AGN.1317, Vopt = 4.25 × 105 km s-1 (z = 1.4162, G10). The spectrum has a flux density (SCO) scale from − 0.7 to 2.2 mJy, a velocity scale from − 1050 to 1050 km s-1 (lower x-axis), and a z scale from 1.4128 to 1.4197 (upper x-axis). The Gaussian fit and the vertical dot-dashed line show that the 12CO(2−1) emission is blue-shifted by ~61 km s-1 with respect to the optical emission (G10).
