Spectral Energy and Age Distributions for 51 Globular Cluster Candidates
Jun Ma, Xu Zhou, Jiansheng Chen +5
This paper is the fourth in a series presenting spectrophotometry of 51 globular cluster candidates, that were detected by Mochejska et al. in the nearby galaxy M33 using the data…
Spectral Energy Distributions and Age Estimates of 172 Globular Clusters in M31
Linhua Jiang, Jun Ma, Xu Zhou +3
In this paper we present CCD multicolor photometry for 172 globular clusters (GCs), taken from the Bologna catalog (Battistini et al. 1987), in the nearby spiral galaxy M31. The ob…
Photometric Redshift Determination with the BATC Multicolor System
Lifang Xia, Xu Zhou, Jun Ma +6
In this paper, we present the methodology of photometric redshift determination with the BATC 15-color system by using hyperz program. Both simulated galaxies and real galaxies wit…
15 colour photometry of Landolt SA95 standard star field
Xu Zhou, Zhaoji Jiang, Jun Ma +6
In this paper, we present a set of photometric observations in 15 colors of stars in the Landolt covered by the system range from 300 nm to 1000 nm. Visual magnitudes of the stars…
Multicolor photometry of 145 of the HII regions in M33
Linhua Jiang, Jun Ma, Xu Zhou +5
This paper is the first in a series presenting CCD multicolor photometry for 145 HII regions, selected from 369 candidate regions from Boulesteix et al. (1974), in the nearby spira…
Spectral Energy Distributions and Age Estimates of 78 Star Clusters in M33
Jun Ma, Xu Zhou, Jiansheng Chen +4
In this third paper of our series, we present CCD spectrophotometry of 78 star clusters that were detected by Chandar, Bianchi, & Ford in the nearby spiral galaxy M33. CCD images o…
