The Aquarius Superclusters - I. Identification of Clusters and Superclusters
Cesar A. Caretta, Marcio A. G. Maia, Wataru Kawasaki +1
We study the distribution of galaxies and galaxy clusters in a 10^deg x 6^deg field in the Aquarius region. In addition to 63 clusters in the literature, we have found 39 new candi…
Environmental effects in galaxies: Molecular Gas, Star Formation, and Activity
Duilia F. de Mello, Tommy Wiklind, Marcio A. G. Maia
In order to study whether there is any correlation between nuclear activities, gas content, and the environment where galaxies reside, we have obtained optical and millimetric spec…
Environmental Effects in Galaxies: The Data
Duilia F. de Mello, Marcio A. G. Maia, Tommy Wiklind
We present optical and millimetric data for 47 intermediate Hubble type spiral galaxies located either in dense environments or in the field. We compare correlations between global…
Redshift-Space Distortions of Group and Galaxy Correlations
Nelson D. Padilla, Manuel E. Merchán, Carlos A. Valotto +2
The two-point correlation function is computed for galaxies and groups of galaxies selected using 3-dimensional information from the Updated Zwicky Galaxy Catalog - (UZC). The reds…
