037-B327 in M31: Luminous Globular Cluster or Core of a Former Dwarf Spheroidal Companion to M31?
Jun Ma, Sidney van den Bergh, Hong Wu +6
037-B327 is of interest because it is both the most luminous and the most highly reddened cluster known in M31. Deep observations with the Advanced Camera for Surveys on the Hubble…
Morphological Dependence of Star Formation Properties for the Galaxies in the Merging Galaxy Cluster A2255
Qirong Yuan, Lifang Zhao, Yanbin Yang +2
The merging cluster of galaxies A2255 is covered by the Sloan Digital Sky Survey (SDSS) survey. In this paper we perform a morphological classification on the basis of the SDSS ima…
The Progenitor of Supernova 2004dj in a Star Cluster
Xiaofeng Wang, Yanbin Yang, Tianmeng Zhang +5
The progenitor of type II-plateau supernova (SN) 2004dj is identified with a supergiant in a compact star cluster known as "Sandage Star 96" (S96) in the nearby spiral galaxy NGC 2…
Color and Metallicity Distributions of M81 Globular Clusters
Jun Ma, Xu Zhou, Jiansheng Chen +4
In this paper we present catalogs of photometric and spectroscopic data for M81 globular clusters (GCs). The catalogs include B- and V- photometric and reddening data of 95 GCs, an…
Merger Dynamics of the Pair of Galaxy Clusters -- A399 and A401
Qirong Yuan, Pengfei Yan, Yanbin Yang +1
Convincing evidence of a past interaction between two rich clusters A399 and A401 was recently found by the X-ray imaging observations. In this paper we examine the structure and d…
