19 Jul 2001 | | Subject: | astro-ph | | Affiliation: | IAG-USP, Brazil), C. Mendes de Oliveira (IAG-USP, Brazil), M. Bolte (UCO/Lick Observatory), B. L. Ziegler (Universitätssternwarte Göttingen) and T. H. Puzia (Universitätssternwarte München | | Abstract: | We have obtained deep photometry of NGC 1199 (in HCG 22) and NGC 6868 (in the Telescopium group). Both galaxies are the optically brightest galaxies of their groups. Our analysis of B and R images taken with the Keck II and the VLT/ESO telescopes, detected a population of globular clusters around both galaxies, with total specific frequencies S_N=1.7pm0.6 for NGC 1199 and S_N = 1.3pm0.6 for NGC 6868. The color distributions of the globular cluster systems shows bimodal peaks centered at (B-R)_0 = 1.13pm0.10 and 1.42pm0.10 (NGC 1199) and (B-R)_0=1.12pm0.10 and 1.42pm0.10 (NGC 6868). | | Source: | arXiv, astro-ph/0107364 | | Other source: | [GID 347124] astro-ph/0111043 | | Services: | Forum | Review | PDF | Favorites | |
