The Aspen--Amsterdam Void Finder Comparison Project
Joerg M. Colberg, Frazer Pearce, Caroline Foster +16
Despite a history that dates back at least a quarter of a century studies of voids in the large--scale structure of the Universe are bedevilled by a major problem: there exist a la…
The Norma Cluster (ACO 3627): I. A Dynamical Analysis of the Most Massive Cluster in the Great Attractor
P. A. Woudt, R. C. Kraan-Korteweg, J. Lucey +2
A detailed dynamical analysis of the nearby rich Norma cluster (ACO 3627) is presented. From radial velocities of 296 cluster members, we find a mean velocity of 4871 +/- 54 km/s a…
Nearby Large-Scale Structures and the Zone of Avoidance: A Conference Summary and Assessment
Anthony Fairall, Ofer Lahav
This conference has brought together many of the world's `cosmographers', particularly those focussed on the mapping nearby large-scale structures. Not surprisingly, numerous portr…
Percolation Properties of Nearby Large-Scale Structures: Every Galaxy has a Neighbour
Anthony Fairall, D. Turner, M. L. Pretorius +4
The distribution of nearby (cz < 7500 km/s) galaxies has been explored by minimal spanning trees; allowance has been made for the drastic decrease of data with distance. The invest…
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…
A Search of the Zone of Avoidance in Scorpius
A. P. Fairall, Renee C. Kraan-Korteweg
An optical search of the Scorpius region - close to the Galactic bulge - has revealed some 1400 partially-obscured galaxies. Redshifts have been obtained for nearly a hundred of th…
