TRACING THE OUTER HALO IN A GIANT ELLIPTICAL TO 25 Reff
Abstract
We have used the Advanced Camera for Surveys and Wide Field Camera 3 cameras on board the Hubble Space Telescope to resolve stars in the halo of the nearest giant elliptical (gE) galaxy NGC 5128 out to a projected distance of 140 kpc (25 effective radii, Reff) along the major axis and 90 kpc (16 Reff) along the minor axis. This data set provides an unprecedented radial coverage of the stellar halo properties in any gE galaxy. Color–magnitude …
