A HST/WFPC2 survey of bright young clusters in M31. I. VdB0, a massive star cluster seen at ~= 25 Myr
S. Perina, P. Barmby, M. A. Beasley +12
{Aims.} We introduce our imaging survey of possible young massive globular clusters in M31 performed with the Wide Field and Planetary Camera 2 (WFPC2) on the Hubble Space Telescop…
Metal Abundance Properties of M81 Globular Cluster System
Jun Ma, David Burstein, Zhou Fan +5
This paper is the third in the series of papers on M81 globular clusters. In this paper, we present spatial and metal abundance properties of 95 M81 globular clusters, which compri…
Age constraints for an M31 globular cluster from SEDs-fit
Jun Ma, Yanbin Yang, David Burstein +4
We have constrained the age of the globular cluster S312 in the Andromeda galaxy (M31) by comparing its multicolor photometry with theoretical stellar population synthesis models.…
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…
UV/Optical Nuclear Activity in the gE Galaxy NGC 1399
R. W. O'Connell, J. R. Martin, J. D. Crane +5
Using HST/STIS, we have detected far-ultraviolet nuclear activity in the giant elliptical galaxy NGC 1399, the central and brightest galaxy in the Fornax I cluster. The source reac…
Peculiar velocities in the Zone of Avoidance: Determining the Distance to the Norma cluster
P. A. Woudt, A. P. Fairall, R. C. Kraan-Korteweg +4
Deep J, H and Ks photometry of the low Galactic latitude Norma cluster has been obtained with the 1.4-m Infrared Survey Facility (IRSF) and with SOFI on the NTT. Together with spec…
