Galaxy groups in the 2dF redshift survey: The catalogue
We construct a galaxy groups catalogue from the public 100K data release of
the 2dF galaxy redshift survey. The group identification is carried out using a
slightly modified version of the group finding algorithm developed by Huchra &
Geller. Several tests using mock catalogues allow us to find the optimal
conditions to increase the reliability of the final group sample. A minimum
number of 4 members, an outer number density enhancement of 80 and a linking
radial cutoff of , are the best obtained values from the
analysis. Using these parameters, approximately 90% of groups identified in
real space have a redshift space counterpart. On the other hand the level of
contamination in redshift space reaches to 30 % including a of
artificial groups and of groups associated with binaries or triplets
in real space. The final sample comprise 2209 galaxy groups covering the sky
region described by Colless et al. spanning over the redshift range of with a mean redshift of 0.1.Comment: Accepted for publication in the MNRAS. 8 figures 8 page
The Local Group as a test of cosmological models
The dynamics of the Local Group and its environment provide a unique
challenge to cosmological models. The velocity field within 5h-1 Mpc of the
Local Group (LG) is extremely ``cold''. The deviation from a pure Hubble flow,
characterized by the observed radial peculiar velocity dispersion, is measured
to be about 60km/s. We compare the local velocity field with similarly defined
regions extracted from N-body simulations of Universes dominated by cold dark
matter (CDM). This test is able to strongly discriminate between models that
have different mean mass densities. We find that neither the Omega=1 (SCDM) nor
Omega=0.3 (OCDM) cold dark matter models can produce a single candidate Local
Group that is embedded in a region with such small peculiar velocities. For
these models, we measure velocity dispersions between 500-700km/s and
150-300km/s respectively, more than twice the observed value. Although both CDM
models fail to produce environments similar to those of our Local Group on a
scale of a few Mpc, they can give rise to many binary systems that have similar
orbital properties as the Milky Way--Andromeda system. The local,
gravitationally induced bias of halos in the CDM ``Local Group'' environment,
if defined within a sphere of 10 Mpc around each Local Group is about 1.5,
independent of Omega. No biasing scheme could reconcile the measured velocity
dispersions around Local Groups with the observed one. Identification of binary
systems using a halo finder (named Skid
(http://www-hpcc.astro.washington.edu/tools/DENMAX for a public version)) based
on local density maxima instead of a simple linking algorithm, gives a much
more complete sample. We show that a standard ``friend of friends'' algorithm
would miss 40% of the LG candidates present in the simulations.Comment: Latex file (19 pages) + 13 figures. Submitted to New Astronomy. Two

The Build-up of the Colour-Magnitude Relation as a Function of Environment
We discuss the environmental dependence of galaxy evolution based on deep
panoramic imaging of two distant clusters taken with Suprime-Cam as part of the
PISCES project. By combining with the SDSS data as a local counterpart for
comparison, we construct a large sample of galaxies that spans wide ranges in
environment, time, and stellar mass (or luminosity). We find that colours of
galaxies, especially those of faint galaxies (), change from blue
to red at a break density as we go to denser regions. Based on local and global
densities of galaxies, we classify three environments: field, groups, and
clusters. We show that the cluster colour-magnitude relation is already built
at . In contrast to this, the bright-end of the field colour-magnitude
relation has been vigorously built all the way down to the present-day and the
build-up at the faint-end has not started yet. A possible interpretation of
these results is that galaxies evolve in the 'down-sizing' fashion. That is,
massive galaxies complete their star formation first and the truncation of star
formation is propagated to smaller objects as time progresses. This trend is
likely to depend on environment since the build-up of the colour-magnitude
relation is delayed in lower-density environments. Therefore, we may suggest
that the evolution of galaxies took place earliest in massive galaxies and in
high density regions, and it is delayed in less massive galaxies and in lower
density regions.Comment: 23pages, 19 figures, accepted for publication in MNRA
The Relation Between Halo Shape, Velocity Dispersion and Formation Time
We use dark matter haloes identified in the MareNostrum Universe and galaxy
groups identified in the Sloan Data Release 7 galaxy catalogue, to study the
relation between halo shape and halo dynamics, parametrizing out the mass of
the systems. A strong shape-dynamics, independent of mass, correlation is
present in the simulation data, which we find it to be due to different halo
formation times. Early formation time haloes are, at the present epoch, more
spherical and have higher velocity dispersions than late forming-time haloes.
The halo shape-dynamics correlation, albeit weaker, survives the projection in
2D (ie., among projected shape and 1-D velocity dispersion). A similar
shape-dynamics correlation, independent of mass, is also found in the SDSS DR7
groups of galaxies and in order to investigate its cause we have tested and
used, as a proxy of the group formation time, a concentration parameter. We
have found, as in the case of the simulated haloes, that less concentrated
groups, corresponding to late formation times, have lower velocity dispersions
and higher elongations than groups with higher values of concentration,
corresponding to early formation times.Comment: MNRAS in press (10 pages, 10 figures
