Image Details
Caption: Figure 10.
Top: color images of VCC 2048 constructed from the
Hubble Space Telescope (
HST) ACS
g image (blue), the mean of the
g and
z images (green), and the
z image (red). Different brightness "stretches" emphasize the embedded disk and nucleus (left), the disk (center), and the
outer envelope (right). VCC 2048 is classified as an edge-on S0 by Binggeli et al. (1985) and Ferrarese et al. (2006). It
clearly has an edge-on disk embedded in an ellipsoidal halo. Bottom: false-color images of VCC 2048 as observed (left) and
after subtraction of the model, almost-edge-on (
i
81°) disk that renders the residual isophotes as nearly elliptical as possible. This remnant envelope proves to have structural
parameters characteristic of an Sph galaxy, not a bulge (Figure
12). VCC 2048 is therefore not an S0 galaxy but rather is an Sph,N galaxy with an embedded disk.
