A high-dimensional look at VIPERS galaxies
2014
We investigate how
galaxiesin
VIPERS(the VIMOS Public Extragalactic
Redshift Survey) inhabit the cosmological density field by examining the correlations across the observable parameter space of
galaxyproperties and clustering strength. The high-
dimensional analysisis made manageable by the use of group-finding and regression tools. We find that the major trends in
galaxyproperties can be explained by a single parameter related to
stellar mass. After subtracting this trend, residual correlations remain between
galaxyproperties and the local environment pointing to complex formation dependencies. As a specific application of this work we build subsamples of
galaxieswith specific clustering properties for use in cosmological tests.
