Tracing the Giant Outer Halo of the Mysterious Massive Disk Galaxy M104 I. Photometry of the Extended Globular Cluster Systems
Jisu Kang, Myung Gyoon Lee, In Sung Jang +4
M104 (NGC 4594, the Sombrero galaxy) is a mysterious massive early-type galaxy that shows a dominant bulge and a prominent disk. However, the presence of a halo in M104 has been el…
Fresh Insights on the Kinematics of M49's Globular Cluster System with MMT/Hectospec Spectroscopy
Matthew A. Taylor, Youkyung Ko, Patrick Côté +10
We present the first results of an MMT/Hectospec campaign to measure the kinematics of globular clusters (GCs) around M49 -- the brightest galaxy in the Virgo galaxy cluster, which…
Mysterious Globular Cluster System of the Peculiar Massive Galaxy M85
Youkyung Ko, Myung Gyoon Lee, Hong Soo Park +4
We present a study on stellar population and kinematics of globular clusters (GCs) in the peculiar galaxy M85. We obtain optical spectra of 89 GCs at 8 kpc 160 kpc using th…
A discrete chemo-dynamical model of M87's globular clusters: Kinematics extending to ~ 400 kpc
Chao Li, Ling Zhu, R. J. Long +14
We study the mass distribution and kinematics of the giant elliptical galaxy M87 (NGC 4486) using discrete chemo-dynamical, axisymmetric Jeans equation modelling. Our catalogue com…
The Next Generation Virgo Cluster Survey. XVII. A Search for Planetary Nebulae in Virgo Cluster Globular Clusters
Weijia Sun, Eric W. Peng, Youkyung Ko +11
The occurrence of planetary nebulae (PNe) in globular clusters (GCs) provides an excellent chance to study low-mass stellar evolution in a special (low-metallicity, high stellar de…
A Wide-field Photometric Survey of Globular Clusters in the Peculiar Early-type Galaxy M85
Youkyung Ko, Myung Gyoon Lee, Hong Soo Park +4
We survey globular clusters (GCs) in M85 using -band images of a field obtained with the MegaCam at the 3.6 m Canada-France-Hawaii Telescope. We i…
