The interstellar medium properties of heavily reddened quasarsand companions at z∼ 2.5 with ALMA and JVLA
We study the interstellar medium (ISM) properties of three heavily reddened quasars at z∼ 2.5 and three millimetre-bright companion galaxies near these quasars. New Karl G. Jansky Very Large Array (JVLA) and Atacama Large Millimeter Array (ALMA) observations constrain the CO(1-0), CO(7-6), and [CI]3P2-3P1 line emission and the far-infrared to radio continuum. The gas excitation and physical properties of the ISM are constrained by comparing our observations to photodissociation region models. The ISM in our high-redshift quasars is composed of very high-density, high-temperature gas that is already highly enriched in elements like carbon. One of our quasar hosts is shown to be a close-separation (

Abstract
We study the interstellar medium (ISM) properties of three heavily reddened quasars at z∼ 2.5 and three millimetre-bright companion galaxies near these quasars. New Karl G. Jansky Very Large Array (JVLA) and Atacama Large Millimeter Array (ALMA) observations constrain the CO(1-0), CO(7-6), and [CI]3P2-3P1 line emission and the far-infrared to radio continuum. The gas excitation and physical properties of the ISM are constrained by comparing our observations to photodissociation region models. The ISM in our high-redshift quasars is composed of very high-density, high-temperature gas that is already highly enriched in elements like carbon. One of our quasar hosts is shown to be a close-separation (
