A New Catalog of Globular Clusters in the Milky Way

TL;DR

This paper presents an updated catalog of 157 Milky Way globular clusters, with improved data on their positions, metallicities, structural parameters, and velocity dispersions, serving as a key resource for astrophysical research.

Contribution

It provides the first major revision since 2003, significantly enhancing the data quality and parameter coverage of the globular cluster catalog.

Findings

Updated list of 157 globular clusters

Enhanced accuracy of cluster coordinates and metallicities

Inclusion of central velocity dispersion data

Abstract

A new revision of the McMaster catalog of Milky Way globular clusters is available. This is the first update since 2003 and the biggest single revision since the original version of the catalog published in 1996. The list now contains a total of 157 objects classified as globular clusters. Major upgrades have been made especially to the cluster coordinates, metallicities, and structural profile parameters, and the list of parameters now also includes central velocity dispersion. NB: This paper is a stand-alone publication available only on the astro-ph archive; it will not be published separately in a journal.
