The First Galaxy Cluster Discovered by the VISTA Variables in the Vía Láctea Survey
L. D. Baravalle, J. L. Nilo Castellón, M. V. Alonso +12
We report the first confirmed detection of the galaxy cluster VVV-J144321-611754 at very low latitudes (l = 315.836, b = -1.650) located in the tile d015 of the…
Properties of satellite galaxies in the SDSS photometric survey: luminosities, colours and projected number density profiles
M. Lares, D. G. Lambas, M. J. L. Dominguez
We analyze photometric data in SDSS-DR7 to infer statistical properties of faint satellites associated to isolated bright galaxies (M_r<-20.5) in the redshift range 0.03<z<0.1. The…
Galaxy groups in the 2dF galaxy redshift survey: A Compactness Analysis of Groups
A. Zandivarez, M. J. L. Dominguez, C. J. Ragone +2
A comprehensive study on compactness has been carried out on the 2dF Galaxy Group Catalogue constructed by Merchán & Zandivarez. The compactness indexes defined in this work take i…
Galaxy groups in the 2dF galaxy redshift survey: Luminosity and Mass Statistics
H. J. Martinez, A. Zandivarez, M. E. Merchan +1
Several statistics are applied to groups and galaxies in groups in the Two degree Field Galaxy Redshift Survey. Firstly we estimate the luminosity functions for different subsets o…
Galaxy groups in the 2dF redshift survey: Galaxy Spectral Type Segregation in Groups
M. J. Dominguez, A. A. Zandivarez, H. J. Martinez +3
The behaviour of the relative fraction of galaxies with different spectral types in groups is analysed as a function of projected local galaxy density and the group-centric distanc…
Galaxy groups in the 2dF redshift survey: Effects of Environment on Star Formation
H. J. Martinez, A. Zandivarez, M. Dominguez +2
We estimate the fraction of star forming galaxies in a catalogue of groups, constructed from the 2dF galaxy redshift survey by Merchán & Zandivarez. We use the spectral type pa…
Galaxy Morphological Segregation in Clusters: Local vs. Global Conditions
Mariano Dominguez, Hernan Muriel, Diego G. Lambas
We study the relative fraction of galaxy morphological types in clusters, as a function of the projected local galaxy density and different global parameters: cluster projected gas…
