GALAXIES: EVOLUTION2 van Dokkum et al, 2018, An Enigmatic Population of Luminous Globular Clusters in a Galaxy Lacking Dark Matter # 세줄 요약 # We recently found an ultra-diffuse galaxy (UDG) called NGC1052-DF2 with a half-light radius of Re = 2.2 kpc and little or no dark matter. Their properties are similar to ω Centauri (the brightest and largest globular cluster in the Milky Way), but that the luminosity function of metal-poor globular clusters is not universal and a factor of ∼1000 removed from the relation between globul.. 2022. 1. 2. 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. 이전 1 다음
