A catalogue of velocities in the cluster of galaxies Abell 85

F. Durret, P. Felenbok, C. Lobo, E. Slezak

Abstract
We present a catalogue of velocities for 551 galaxies (and give the coordinates of 39 stars misclassified as galaxies in our photometric plate catalogue) in a region covering about 100(') x 100(') (0.94x0.94 Mpc for an average redshift of 0.0555, assuming H_0=50 km s(-1) Mpc(-1) ) in the direction of the rich cluster ABCG 85. This catalogue includes previously published redshifts by cite[Beers et al. (1991)]{bee91} and cite[Malumuth et al. (1992)]{mal92}, together with our 367 new measurements. A total of 305 galaxies have velocities in the interval 13350-20000 km s(-1) , and will be considered as members of the cluster. ABCG 85 therefore becomes one of the clusters with the highest number of measured redshifts; its optical properties are being investigated in a companion paper. Based on observations collected at the European Southern Observatory, La Silla, Chile.

Institute of Astrophysics and Space Sciences

Institute of Astrophysics and Space Sciences (IA) is a new but long anticipated research infrastructure with a national dimension. It embodies a bold but feasible vision for the development of Astronomy, Astrophysics and Space Sciences in Portugal, taking full advantage and fully realizing the potential created by the national membership of the European Space Agency (ESA) and the European Southern Observatory (ESO). IA resulted from the merging the two most prominent research units in the field in Portugal: the Centre for Astrophysics of the University of Porto (CAUP) and the Center for Astronomy and Astrophysics of the University of Lisbon (CAAUL). It currently hosts more than two-thirds of all active researchers working in Space Sciences in Portugal, and is responsible for an even greater fraction of the national productivity in international ISI journals in the area of Space Sciences. This is the scientific area with the highest relative impact factor (1.65 times above the international average) and the field with the highest average number of citations per article for Portugal.
