Aeree Chung, J. H. van Gorkom, Jeffrey D. P. Kenney, Hugh Crowl, Bernd, Vollmer
TL;DR
This paper presents high-resolution HI imaging data of 53 Virgo cluster galaxies, analyzing their gas properties and morphology to understand environmental effects on galaxy evolution within the cluster.
Contribution
It provides a detailed atlas of HI maps and properties for Virgo galaxies, highlighting environmental influences on their gas and morphology, which was not extensively studied before.
Findings
Over 60% of galaxies are fainter than 12 mag in B_T.
The survey includes a diverse range of galaxy types and environments.
Detailed HI morphology and kinematics are characterized for each galaxy.
Abstract
We present the result of a new VLA HI Imaging survey of Virgo galaxies, VIVA (the VLA Imaging survey of Virgo galaxies in Atomic gas). The survey includes high resolution HI data of 53 carefully selected late type galaxies (48 spirals and 5 irregular systems). The goal is to study environmental effects on HI gas properties of cluster galaxies to understand which physical mechanisms affect galaxy evolution in different density regions, and to establish how far out the impact of the cluster reaches. As a dynamically young cluster, Virgo contains examples of galaxies experiencing a variety of environmental effects. Its nearness allows us to study each galaxy in great detail. We have selected Virgo galaxies with a range of star formation properties in low to high density regions (at the projected distance from M87, d_87=0.3-3.3 Mpc). Contrary to pr evious studies, more than half of the…
