STREGA (STRucture and Evolution of the Galaxy) is an ongoing VLT Survey Telescope Guaranteed Time survey, aimed at investigating the mechanisms of formation and evolution of the Galactic Halo on an area of about 150 square degrees. The core programme searches for the signatures of interaction between selected stellar systems and the Galactic Halo and a complementary part is focussed on exploring the southern portion of the Fornax Stream. The adopted stellar tracers are variable stars and main sequence turn-off stars. We present an overview of the survey, the first results, and the perspectives.

Abstract

STREGA (STRucture and Evolution of the Galaxy) is an ongoing VLT Survey Telescope Guaranteed Time survey, aimed at investigating the mechanisms of formation and evolution of the Galactic Halo on an area of about 150 square degrees. The core programme searches for the signatures of interaction between selected stellar systems and the Galactic Halo and a complementary part is focussed on exploring the southern portion of the Fornax Stream. The adopted stellar tracers are variable stars and main sequence turn-off stars. We present an overview of the survey, the first results, and the perspectives.
