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:
"A survey completed using a combination of ground and space-based telescopes yielded a treasure trove of previously unknown globular clusters – old, dense groups of thousands of stars that all formed at the same time – in the outer regions of the elliptical galaxy Centaurus A. 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...

Based on current health conditions and aligned with CDC guidance as well as our commitment to deliver in-person learning at the University of Arizona, we will require the use of surgical or higher-grade (KN95, KF94) face masks be worn: 1) In all indoor spaces where it is not possible to adequately and continuously maintain social distance. 2) Any building/facility that is operated by or affiliated with the University where...
How Our Largest Dwarf Galaxy Keeps the Others In Line
The LMC is a massive dwarf companion to our Milky Way, with at least a tenth the mass of the Milky Way. It’s swinging around our galaxy for the first time on a trajectory that aligns with the Milky Way's plane of satellites. It seems unlikely that this alignment is a coincidence. New research led by Nico Garavito Camargo (Arizona Ph.D., 2021), Ekta Patel (Arizona Ph.D., 2019) and...
