Abstract
In this VERTICO early science paper we explore in detail how environmental mechanisms, identified in Hᵢ, affect the resolved properties of molecular gas reservoirs in cluster galaxies. The molecular gas is probed using ALMA ACA (+TP) observations of ¹²CO(2-1) in 51 spiral galaxies in the Virgo cluster (of which 49 are detected), all of which are included in the VIVA Hᵢ survey. The sample spans a stellar mass range of 9≤logM∗/M⊙≤11 . We study molecular gas radial profiles, isodensity radii, and surface densities as a function of galaxy Hᵢ deficiency and morphology. There is a weak correlation between global Hᵢ and H₂ deficiencies, and resolved properties of molecular gas correlate with Hᵢ deficiency: galaxies that have large Hᵢ deficiencies have relatively steep and truncated molecular gas radial profiles, which is due to the removal of low-surface-density molecular gas on the outskirts. Therefore, while the environmental mechanisms observed in Hᵢ also affect molecular gas reservoirs, there is only a moderate reduction of the total amount of molecular gas.
