VISTA Variables in the Via Lactea (VVV): The public ESO near-IR variability survey of the Milky Way
We describe the public ESO near-IR variability survey (VVV) scanning the Milky Way bulge and an adjacent section of the mid-plane where star formation activity is high. The survey will take 1929 hours of observations with the 4-metre VISTA telescope during five years (2010 − 2014), covering ∼ 109 point sources across an area of 520 deg2, including 33 known globular clusters and ∼350 open cluste...
متن کاملMilky Way
7 Globular clusters and Population II stars are fossil remnants of the first major epoch of star formation in the Milky Way. SIM Lite will determine precise distances to selected Pop II objects to define a reliable distance scale, and establish reliable absolute and relative ages. Those ages set a minimum age for the Universe and map the early formation history of the Milky Way. The resultant a...
متن کاملVVV DR1: The First Data Release of the Milky Way Bulge and Southern Plane from the Near-Infrared ESO Public Survey VISTA Variables in the Vı́a Láctea
Context. The ESO Public Survey VISTA Variables in the Vı́a Láctea (VVV) started in 2010. VVV targets 562 sq. deg in the Galactic bulge and an adjacent plane region and is expected to run for ∼ 5 years. Aims. In this paper we describe the progress of the survey observations in the first observing season, the observing strategy and quality of the data
متن کاملAntimatter in the Milky Way
Observational signatures of existence of antimatter objects in the Galaxy are discussed. We focus on point-like sources of gamma radiation, diffuse galactic gamma ray background and anti-nuclei in cosmic rays.
متن کاملFormation of the Milky Way
We review observational evidence bearing on the formation of a prototypical large spiral galaxy, the Milky Way. New groundand space-based studies of globular star clusters and dwarf spheroidal galaxies provide a wealth of information to constrain theories of galaxy formation. It appears likely that the Milky Way formed by an combination of rapid, dissipative collapse and mergers, but the relati...
