Compact stellar systems in the Fornax cluster: a UV perspective
Steffen Mieske, Michael Hilker, Dominik J. Bomans +4
In recent years, increasing evidence for chemical complexity and multiple stellar populations in massive globular clusters (GCs) has emerged, including extreme horizontal branches…
On the Origin of Bimodal Horizontal-Branches in Massive Globular Clusters: The Case of NGC 6388 and NGC 6441
Suk-Jin Yoon, Seok-Joo Joo, Chang H. Ree +3
Despite the efforts of the past decade, the origin of the bimodal horizontal-branch (HB) found in some globular clusters (GCs) remains a conundrum. Inspired by the discovery of mul…
GALEX Ultraviolet Photometry of Globular Clusters in M31: Three Year Results and a Catalog
Soo-Chang Rey, R. Michael Rich, Sangmo T. Sohn +23
We present ultraviolet (UV) photometry of M31 globular clusters (GCs) found in 23 Galaxy Evolution Explorer (GALEX) images covering the entirety of M31. We detect 485 and 273 GCs (…
UV Upturn in Elliptical Galaxies: Theory
Sukyoung K. Yi, Suk-Jin Yoon
The UV upturn is the rising flux with decreasing wavelength between the Lyman limit and 2500Åfound virtually in all bright spheroidal galaxies. It has been a mystery ever since it…
Explaining the Color Distributions of Globular Cluster Systems in Elliptical Galaxies
Suk-Jin Yoon, Sukyoung Ken Yi, Young-Wook Lee
The colors of globular clusters in most of large elliptical galaxies are bimodal. This is generally taken as evidence for the presence of two cluster subpopulations that have diffe…
Super Helium-Rich Population and the Origin of Extreme Horizontal-Branch Stars in Globular Clusters
Young-Wook Lee, Seok-Joo Joo, Sang-Il Han +7
Recent observations for the color-magnitude diagrams (CMDs) of the massive globular cluster Omega Centauri have shown that it has a striking double main sequence (MS), with a minor…
