Galaxies2 Chies-Santos et al., 2012, An optical/NIR survey of globular clusters in early-type galaxies. III. On the colour bimodality of globular cluster systems # 세줄 요약 # We study optical/near-infrared (NIR) colour distributions of the GC systems in 14 E/S0 galaxies. We find that double-peaked colour distributions are more commonly seen in optical than in optical/NIR colours A bimodal optical colour distribution is not necessarily an indication of an underlying bimodal metallicity distribution. # 상세 리뷰 # 1.

Pota et al., 2015, A SLUGGS and Gemini/GMOS combined study of the elliptical galaxyM60: wide-field photometry and kinematics of the globular cluster system # 세줄 요약 # We present new wide-field photometry and spectroscopy of the globular clusters (GCs) around NGC 4649 (M60), the third brightest galaxy in the Virgo cluster. We confirm significant GC colour bimodality and find that the red GCs are more centrally concentrated, while the blue GCs are more spatially extended. We find that formation via a major merger between two gas-poor galaxies, followe.. 2021. 8. 23. 이전 1 다음
