NGC 3923 MegaCam image

Listed in IVOA Registry (Virtual Observatory)

The elliptical galaxy NGC 3923 is known to be surrounded by a number of stellar shells, probable remnants of an accreted galaxy.

Description

Despite its uniqueness, the deepest images of its outskirts come from the 1980s. On the basis of the modified Newtonian dynamics (MOND), it has recently been predicted that a new shell lies in this region.

We obtain the deepest image ever of the galaxy, map the tidal features in it, and search for the predicted shell. The image of the galaxy was taken by the MegaCam camera at the Canada-France-Hawaii Telescope in the g'-band. It reached the surface-brightness limit of 29mag/arcsec^2^.

In addition, we reanalyzed an archival HST image of the galaxy.
