The EMBLA Survey -- Metal-poor stars in the Galactic bulge
Louise M. Howes, Martin Asplund, Stefan C. Keller +14
Cosmological models predict the oldest stars in the Galaxy should be found closest to the centre of the potential well, in the bulge. The EMBLA Survey successfully searched for the…
Extremely metal-poor stars from the cosmic dawn in the bulge of the Milky Way
L. M. Howes, A. R. Casey, M. Asplund +22
The first stars are predicted to have formed within 200 million years after the Big Bang, initiating the cosmic dawn. A true first star has not yet been discovered, although stars…
Selecting Sagittarius: Identification and Chemical Characterization of the Sagittarius Stream
E. A. Hyde, S. Keller, D. B. Zucker +11
Wrapping around the Milky Way, the Sagittarius stream is the dominant substructure in the halo. Our statistical selection method has allowed us to identify 106 highly likely member…
The GALAH Survey: Scientific Motivation
G. M. De Silva, K. C. Freeman, J. Bland-Hawthorn +44
The GALAH survey is a large high-resolution spectroscopic survey using the newly commissioned HERMES spectrograph on the Anglo-Australian Telescope. The HERMES spectrograph provide…
Palomar 5 and its Tidal Tails: A Search for New Members in the Tidal Stream
Pete Kuzma, Gary Da Costa, Stefan Keller +1
In this paper we present the results of a search for members of the globular cluster Palomar 5 and its associated tidal tails. The analysis has been performed using intermediate an…
Gemini/GMOS photometry of intermediate-age star clusters in the Large Magellanic Cloud
Andres E. Piatti, Stefan C. Keller, A. Dougal Mackey +1
We present Gemini South GMOS g,i photometry of 14 intermediate-age Large Magellanic Cloud (LMC) star clusters, namely: NGC 2155, 2161, 2162, 2173, 2203, 2209, 2213, 2231, 2249, Hod…
