Architecture of CenA as Seen in Newly Discovered Globular Clusters

Graduate student Allison Hughes and her colleagues (Associate Professor Dave Sand and others) were privileged to give one of the AAS press conferences to go along with meeting 239 (the in-person meeting was canceled due to COVID). What follows was written by Daniel Stolte and linked HERE from UANews:

The work presents a significant advance in understanding the architecture and cosmological history of this galaxy and offers new insights into galaxy formation in general and the distribution of dark matter in the universe.

Allison Hughes, a doctoral student in the University of Arizona Department of Astronomy and Steward Observatory, is the first author of a peer-reviewed paper summarizing the findings, which was published in the Astrophysical Journal in...
