Voyage 2050 White Paper: All-Sky Visible and Near Infrared Space Astrometry
David Hobbs, Anthony Brown, Erik Høg +27
A new all-sky visible and Near-InfraRed (NIR) space astrometry mission with a wavelength cutoff in the K-band is not just focused on a single or small number of key science cases.…
Mapping the stellar age of the Milky Way bulge with the VVV. II. Deep JKs catalogs release based on PSF photometry
F. Surot, E. Valenti, S. L. Hidalgo +6
The bulge represents the best compromise between old and massive Galactic component, and as such its study is a valuable opportunity to understand how the bulk of the Milky Way for…
Mapping the stellar age of the Milky Way bulge with the VVV. I. The method
F. Surot, E. Valenti, S. L. Hidalgo +8
Recent observational programmes are providing a global view of the Milky Way bulge that serves as template for detailed comparison with models and extragalactic bulges. A number of…
First stellar spectroscopy in Leo P
C. J. Evans, N. Castro, O. A. Gonzalez +11
We present the first stellar spectroscopy in the low-luminosity (M_V ~-9.3 mag), dwarf galaxy Leo P. Its significantly low oxygen abundance (3% solar) and relative proximity (~1.6…
