Globular Clusters in Early-Type Galaxies with GMOS
Terry Bridges, Mike Beasley, Favio Faifer +6
We present recent results from our long-term Gemini/GMOS study of globular clusters in early-type galaxies. To date, we have obtained photometry and spectroscopy for clusters in NG…
The Formation and Evolution of Star Clusters and Galaxies
Stephen E. Zepf
This paper addresses the questions of what we have learned about how and when dense star clusters form, and what studies of star clusters have revealed about galaxy formation and e…
Formation Scenarios for Globular Clusters and Their Host Galaxies
Stephen E. Zepf
This review focuses on how galaxies and their globular cluster systems form. I first discuss the now fairly convincing evidence that some globular clusters form in galaxy starburst…
A Cepheid distance to NGC 4258
Eyal Maoz, Jeffrey A. Newman, Laura Ferrarese +5
Distances measured using Cepheid variable stars have been essential for establishing the cosmological distance scale and the value of the Hubble constant. These stars have remained…
The Absence of Passively Evolving Ellipticals in Deep Optical and Near-Infrared Surveys
Stephen E. Zepf
The traditional view of elliptical galaxies has been that they formed in a single, rapid burst of star formation at high redshift, and have evolved quiescently since that time. In…
The Faint End of the Luminosity Function of Galaxies in Compact Groups
Stephen E. Zepf, Reinaldo R. de Carvalho, Andre L. B. Ribeiro
We study the luminosity function of galaxies in Hickson groups using our recent redshift survey of galaxies in and around 17 of these groups. We find that the galaxies in these reg…
