Globular Clusters3 [석사학위논문] Jong-Hoon Jeong et al., 2018, Near-Infrared Color-Metallicity Relation for Globular ClusterSystem in Elliptical Galaxy NGC 4649 # 세줄 요약 # Use Optical and NIR photometry of M60 GC system to examine the GC color distribution morphologies. Through Optical color & Opt-NIR color relation, we try to deduce the exact shape of CMR, then We use YEPS model to derive the metallicity distribution function (MDF) & color-metallicity relation (CMR) of NGC 4649 GC (* Why NIR Observation? ⇒ directly measures the metallicity of GCs). Our .. 2023. 8. 30. Cohen & Blakeslee & Ryzhov, 1998, The Ages and Abundances of a Large Sample of M87 Globular Clusters # 세줄 요약 # Combining the new (20 GCs; this paper) and existing data (150 GCs; Cohen & Ryzhov, 1997) for the galactic GCs (Globular clusters) and comparing the (U-R) colors and the line indices gave qualitative indications for the ages and abundances of M87 GC system. We find that the M87 GCs span a wide range in metallicity, from very metal-poor to somewhat above solar metallicity. The behavior o.. 2021. 8. 28. 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
