VERTICO: The Virgo Environment Traced in CO

 

 

ALMA Large Program | Project Code: 2019.1.00763.L | Cycle 7

PI: Toby Brown (HAA-NRC)

AGE-PRO.png

The VERTICO—Virgo Environment Traced in Carbon Monoxide—Survey observed the gas reservoirs in 51 galaxies in the nearby Virgo Cluster and found that the extreme environment in the cluster was killing galaxies by robbing them of their star-forming fuel. In this composite image, ALMA’s radio wavelength observations of the VERTICO galaxies’ molecular gas disks are magnified by a factor of 20. They are overlaid on the X-ray image of the hot plasma within the Virgo Cluster.

1. Program Abstract

 

The Virgo Environment Traced in CO (VERTICO) survey was designed to map 12CO(2-1), 13CO(2-1), and C18O(2-1) in 51 Virgo Cluster galaxies (36 new + 15 archival) with the Atacama Compact Array, part of the Atacama Large Millimeter/submillimeter Array. The primary motivation of VERTICO is to understand the physical mechanisms that perturb molecular gas disks, and therefore star formation and galaxy evolution, in dense environments. With this in mind, the survey provides a homogeneous legacy data set for studying galaxy evolution in our closest cluster. Brown et al. (2021) provides an overview of VERTICO's design and sample selection, 12CO(2-1) observations, and data reduction procedures.
