The Nature of the Density Clump in the Fornax Dwarf Spheroidal Galaxy

Olszewski, Edward W; Mateo, Mario; Harris, Jason; Walker, Matthew G; Coleman, Matthew; Da Costa, Gary

Description

We have imaged the recently discovered stellar overdensity located approximately one core radius from the center of the Fornax dwarf spheroidal galaxy using the Magellan Clay 6.5 m telescope with the Magellan Instant Camera. Superb seeing conditions allowed us to probe the stellar populations of this overdensity and of a control field within Fornax to a limiting magnitude of R = 26. The color-magnitude diagram of the overdensity field is virtually identical to that of the control field, with...[Show more]
