Jose dos Campos, Brazil), Museu de Astronomia e Ciencias Afins (Rio de Janeiro, Brazil), Observatorio do Valongo (Rio de Janeir | | Abstract: | We present spectroscopic and photometric data for 920 galaxies selected in 68 fields of the Aquarius Cluster Catalog. Typically the 15 brightest candidate members with magnitudes in the range 16 < b_J < 21 were selected for observations, and ~ 71% turn out to be cluster members. Using the new redshift determinations we assign galaxies to groups and clusters, and by including data from the literature we calculate systemic velocities and velocity dispersions for 74 clusters, each with redshifts measured for at least 6 individual galaxies. | | Source: | arXiv, astro-ph/0409742 | | Services: | Forum | Review | PDF | Favorites | |
