Abstract:
We investigate the effect of the environment on the Faber-Jackson (FJ)
relation, using a sample of 384 nearby elliptical galaxies and
estimating objectively their environment on the typical scale of
galaxy clusters. We show that the intrinsic scatter of the FJ relation
is significantly reduced when ellipticals in high-density environments
are compared to ellipticals in low-density ones. This result, which
holds in a limited range of overdensities, is likely to provide an
important observational link between scaling relations and formation
mechanisms in galaxies.
Description:
We have extracted the sample of elliptical galaxies from HyperLeda
(Paturel et al. 2003, Cat. VII/237), requiring them to have σ0
measured, mB≤15.5, 2000km/s≤vr≤10000km/s, and δ≥0°.
