2/26/2023 0 Comments Mol quasarThere is however room for up to MmolCGM ∼ 1.7 × 1012 M⊙, once optically thick CO emission with αCO = 3.6 M⊙ (K km s−1 pc2)−1 and L′CO(3−2)/L′CO(1−0) = 0.5 are assumed. Using the optically thin assumption, we estimate a strict lower limit for the total molecular CGM mass observed by ACA of MmolCGM > 1010 M⊙. It shows complex kinematics, with an overall broad line profile (FWHM = 1000 km s−1) that is skewed towards redshifted velocities up to at least v ∼ 1000 km s−1. This is the most extended molecular circumgalactic medium (CGM) reservoir that has ever been mapped. Such additional CO(3−2) emission traces a structure that extends out to r ∼ 200 kpc in projected size, as inferred through direct imaging and confirmed by an analysis of the uv visibilities. New Atacama Compact Array (ACA) CO(3−2) observations detect a much higher flux (by a factor of 14 ± 5) than measured on kiloparsec scales (r ≲ 8 kpc) using previous snapshot Atacama Large Millimeter/submillimeter Array data. However, the origin of such an extended molecular CGM remains unclear.We present the discovery of copious molecular gas in the halo of cid_346, a z = 2.2 quasar studied as part of the SINFONI survey for Unveiling the Physics and Effect of Radiative feedback (SUPER). Since cid_346 hosts quasar-driven ionised outflows and since there is no evidence of merging companions or an overdensity, we suggest that outflows may have played a crucial rule in seeding metal-enriched, dense gas on halo scales. There is however room for up to M mol CGM ∼ 1.7 × 10 12 M ⊙, once optically thick CO emission with α CO = 3.6 M ⊙ (K km s −1 pc 2) −1 and L ′ CO(3−2)/ L ′ CO(1−0) = 0.5 are assumed. Using the optically thin assumption, we estimate a strict lower limit for the total molecular CGM mass observed by ACA of M mol CGM > 10 10 M ⊙.
