A New Red Giant-based Distance Modulus of 13.3 Mpc to the Antennae Galaxies and Its Consequences

Saviane, Ivo; Momany, Y; Da Costa, Gary; Richards, M; Hibbard, John E

Description

The Antennae galaxies are the closest example of an ongoing major galaxy merger and, as such, represent a unique laboratory for furthering the understanding of the formation of exotic objects (e.g., tidal dwarf galaxies, ultraluminous X-ray sources, super stellar clusters). In a previous paper HST WFPC2 observations were used to demonstrate that the Antennae system might be at a distance considerably less than that conventionally assumed in the literature. Here we report new, much deeper HST...[Show more]
