Abstract:
We describe the motivation, field locations and stellar selection for
the Abundances and Radial velocity Galactic Origins Survey (ARGOS)
spectroscopic survey of 28000 stars in the bulge and inner disc of the
Milky Way galaxy across latitudes of b=-5° to -10°. The
primary goal of this survey is to constrain the formation processes of
the bulge and establish whether it is predominantly a merger or
instability remnant. From the spectra (R=11000), we have measured
radial velocities and determined stellar parameters, including
metallicities and [α/Fe] ratios. Distances were estimated from
the derived stellar parameters and about 14000 stars are red giants
within 3.5kpc of the Galactic Centre. In this paper, we present the
observations and analysis methods. Subsequent papers (III and IV) will
discuss the stellar metallicity distribution and kinematics of the
Galactic bulge and inner disc, and the implications for the formation
of the bulge.
Description:
The spectra were acquired with the fibre-fed AAOmega system on the
Anglo-Australian Telescope in 2008-2011 May-August.
