Core collapse and horizontal-branch morphology in galactic globular clusters
Mario Pasquato, Gabriella Raimondo, Enzo Brocato +3
Context. Stellar collision rates in globular clusters (GCs) do not appear to correlate with horizontal branch (HB) morphology, sug- gesting that dynamics does not play a role in th…
The effect of second generation populations on the integrated colors of metal-rich globular clusters in early-type galaxies
Chul Chung, Sang-Yoon Lee, Suk-Jin Yoon +1
The mean color of globular clusters (GCs) in early-type galaxies is in general bluer than the integrated color of halo field stars in host galaxies. Metal-rich GCs often appear mor…
Nonlinear Color-Metallicity Relations of Globular Clusters. V. Nonlinear Absorption-line Index versus Metallicity Relations and Bimodal Index Distributions of M31 Globular Clusters
Sooyoung Kim, Suk-Jin Yoon, Chul Chung +5
Recent spectroscopy on the globular cluster (GC) system of M31 with unprecedented precision witnessed a clear bimodality in absorption-line index distributions of old GCs. Such div…
Nonlinear Color-Metallicity Relations of Globular Clusters. IV. Testing the Nonlinearity Scenario for Color Bimodality via HST/WFC3 u-band Photometry of M84 (NGC 4374)
Suk-Jin Yoon, Sangmo T. Sohn, Hak-Sub Kim +4
Color distributions of globular clusters (GCs) in most massive galaxies are bimodal. Assuming linear color-to-metallicity conversions, bimodality is viewed as the presence of merel…
Wide-Field Multiband Photometry of Globular Cluster Systems in the Fornax Galaxy Cluster
Hak-Sub Kim, Suk-Jin Yoon, Sangmo Tony Sohn +5
We present wide-field multiband photometry of globular cluster (GC) systems in NGC 1399, NGC 1404, and NGC 1387 located at the central region of the Fornax galaxy cluster. Observat…
