Optical Photometry of Type II-P Supernova 2004dj in NGC 2403
Tianmeng Zhang, Xiaofeng Wang, Weidong Li +4
We present photometric data of the type II-P supernova (SN) 2004dj in NGC 2403. The multicolor light curves cover the SN from 60 to 200 days after explosion, and are measure…
Spectral Energy Distributions of M81 Globular Clusters in BATC Multicolor Survey
Jun Ma, Xu Zhou, David Burstein +4
In this paper, we give the spectral energy distributions of 42 M81 globular clusters in 13 intermediate-band filters from 4000 to 10000 A, using the CCD images of M81 observed as p…
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…
Identification of X-ray Point Sources and Study on the Nature of 62 X-ray Globular Cluster Candidates in M31
Zhou Fan, Jun Ma, Xu Zhou +3
This paper includes two parts. The first is to present the spectral energy distributions (SEDs) of 49 globular cluster (GC) X-ray sources in the BATC 13 intermediate-band filters f…
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…
Optical Monitoring of PKS 1510-089: A Binary Black Hole System?
J. Wu, X. Zhou, B. Peng +3
Three deep flux minima were observed with nearly the same time-scales and intervals for the blazar PKS 1510-089 in the past few years. A binary black hole system was proposed to be…
