J/MNRAS/390/1133  Anisotropic distribution of satellite galaxies (Bailin+, 2008)

The anisotropic distribution of satellite galaxies. Bailin J., Power C., Norberg P., Zaritsky D., Gibson B.K. <Mon. Not. R. Astron. Soc., 390, 1133-1156 (2008)> =2008MNRAS.390.1133B

Using mock catalogues generated from cosmological N-body simulations, we demonstrate that the selection criteria used to select isolated galaxies and their satellites in large galaxy redshift surveys must be very strict in order to correctly identify systems in which the primary galaxy dominates its environment. We demonstrate that the criteria used in many previous studies instead select predominantly group members. We refine a set of selection criteria for which the group contamination is estimated to be less than 7 per cent and present a catalogue of the resulting sample. Description: Our sample is drawn from the SDSS Data Release 6 (DR6). File Summary:

Note (1): When no satellite name, values for the Primary galaxy, else values for the satellite galaxy. Note (2): Based on the classification scheme of Bailin & Harris (2008ApJ...681..225B) as follows: E = early-type I = intermediate-type L = late-type Note (3): Whether the system passes all quality cuts required to be included in the sample for the purposes of measuring the anisotropy with respect to the primary Note (4): Whether the system passes all quality cuts required to be included in the sample for the purposes of measuring the anisotropy with respect to the LSS (Large Scale Structure).
