Ma. Beasley et Rm. Sharples, Spectroscopy of globular cluster candidates in the Sculptor group galaxiesNGC 253 and 55, M NOT R AST, 311(4), 2000, pp. 673-682
We have obtained spectra for 103 published globular cluster candidates in t
he Sculptor group galaxies NGC 253 and 55. On the basis of radial velocitie
s and digitized plate images, 14 globular clusters are identified in NGC 25
3 and one probable globular cluster is identified in NGC 55. The majority o
f the objects in the sample appear to be background galaxies. We have obtai
ned and analysed COSMOS plate scans of NGC 253 and 55 and use these along w
ith the spectroscopically identified clusters to define new samples of glob
ular cluster candidates in the two galaxies which should have reduced conta
mination.
