Nikki Zabel, Toby Brown, Christine D. Wilson +17
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 galax…
Cold Gas in Massive Galaxies as A Critical Test of Black Hole Feedback Models

We present the Virgo Environment Traced in CO (VERTICO) survey, a new effort to map CO(), CO(), and CO() in 51 Virgo Cluster galaxies with the A…
Drivers of asymmetry in synthetic H I emission-line profiles of galaxies in the EAGLE simulation
Aditya Manuwal, Aaron D. Ludlow, Adam R. H. Stevens +2
We study the shapes of spatially integrated H I emission-line profiles of galaxies in the EAGLE simulation using three separate measures of the profile's asymmetry. We show that th…
