The GALAH Survey: Chemical Clocks
Michael R. Hayden, Sanjib Sharma, Joss Bland-Hawthorn +27
Previous studies have found that the elemental abundances of a star correlate directly with its age and metallicity. Using this knowledge, we derive ages for a sample of 250,000 st…
The GALAH survey: properties of the Galactic disk(s) in the solar neighbourhood
L. Duong, K. C. Freeman, M. Asplund +26
Using data from the GALAH pilot survey, we determine properties of the Galactic thin and thick disks near the solar neighbourhood. The data cover a small range of Galactocentric ra…
The GALAH survey: Chemical Tagging of Star Clusters and New Members in the Pleiades
Janez Kos, Joss Bland-Hawthorn, Ken Freeman +25
The technique of chemical tagging uses the elemental abundances of stellar atmospheres to `reconstruct' chemically homogeneous star clusters that have long since dispersed. The GAL…
Theia: Faint objects in motion or the new astrometry frontier
The Theia Collaboration, Celine Boehm, Alberto Krone-Martins +96
In the context of the ESA M5 (medium mission) call we proposed a new satellite mission, Theia, based on relative astrometry and extreme precision to study the motion of very faint…
The Radial Velocity Experiment (RAVE): Fifth Data Release
Andrea Kunder, Georges Kordopatis, Matthias Steinmetz +51
Data Release 5 (DR5) of the Radial Velocity Experiment (RAVE) is the fifth data release from a magnitude-limited (9< I < 12) survey of stars randomly selected in the southern hemis…
SPACE: the SPectroscopic All-sky Cosmic Explorer
A. Cimatti, M. Robberto, C. M. Baugh +18
We describe the scientific motivations, the mission concept and the instrumentation of SPACE, a class-M mission proposed for concept study at the first call of the ESA Cosmic-Visio…
The Observed properties of Dark Matter on small spatial scales
Gerard Gilmore, Mark I. Wilkinson, Rosemary F. G. Wyse +3
We present a synthesis of recent photometric and kinematic data for several of the most dark-matter dominated galaxies. There is a bimodal distribution in half-light radii, with st…
Cats and Dogs, Hair and A Hero: A Quintet of New Milky Way Companions
V. Belokurov, D. B. Zucker, N. W. Evans +31
We present five new satellites of the Milky Way discovered in Sloan Digital Sky Survey (SDSS) imaging data, four of which were followed-up with either the Subaru or the Isaac Newto…
The Field of Streams: Sagittarius and its Siblings
V. Belokurov, D. B. Zucker, N. W. Evans +18
We use Sloan Digital Sky Survey (SDSS) Data Release 5 (DR5) u,g,r,i,z photometry to study Milky Way halo substructure in the area around the North Galactic Cap. A simple color cut…
Dynamics and the Origin of Low-Mass Galaxies in the Virgo Cluster
Christopher J. Conselice, John S. Gallagher, Rosemary F. G. Wyse
Early-type dwarfs are the most common galaxy in the local universe, yet their origin and evolution remain a mystery. Various cosmological scenarios predict that dwarf-like galaxies…
ISOGAL-DENIS detection of red giants with weak mass loss in the Galactic Bulge
A. Omont, S. Ganesh, C. Alard +21
The ISOGAL project is a survey of the stellar populations, structure, and recent star formation history of the inner disk and bulge of the Galaxy. ISOGAL combines 15 and 7micron IS…
Galactic Structure and Stellar Populations
Rosemary F. G. Wyse
Invited review given at special session on Digitizing the Sky at 1994 Summer AAS meeting, Minnesota.
