Abstract:
We have conducted a large scale blind survey for molecular absorption at high redshifts, using the CO/HCO+ rotational transitions. We have observed 549 radio-selected sources in the Ka and Q bands, in the frequency range 32-48 GHz, using the Karl G. Jansky Very Large Array, covering the redshift range 0.85 < z < 2.60, and 2.72 < z < 4.57 , with a median redshift of z = 1.5.
