Abstract:
The most luminous galaxies in the blue passband have a larger
correlation amplitude than L* galaxies. They do not appear to be
preferentially located in rich clusters or groups, but a significant
fraction of them seem to be in systems which include fainter members.
We present an analysis of fields centered on 18 Very Luminous Galaxies
(MB≤-21) selected from the Southern Sky Redshift Survey 2 (Cat.
J/AJ/116/1, based on new observations and public data of the 2dF
Galaxy Redshift Survey (Cat. VII/226); we present also additional
data on a CfA VLG and on Arp 127.
Description:
Three VLGs were selected from our catalogue of VLGs (see Table 1 of
Paper I, Cappi et al., 1998A&A...335..779C 1998A&A...335..779C), while a fourth galaxy
satisfying the VLG definition was selected from the CfA catalogue (see
Geller & Huchra, 1989Sci...246..897G 1989Sci...246..897G); the 4 VLG fields were observed
at OHP. Other 15 VLG fields were extracted from the 2dFGRS public
catalogue (Cat. VII/226), which has an overlap with the SSRS2 (Cat.
J/AJ/116/1). While partially imposed by observational constraints
(see below), our selection is random with respect to the VLG
properties, and should be representative of the whole sample. In fact,
one third of the selected VLGs are early-type galaxies, a fraction
consistent with that of the total sample published in Paper I, Cappi
et al. (1998A&A...335..779C 1998A&A...335..779C).
