The Galactic Archaeology with HERMES (GALAH) survey is a large high-resolution spectroscopic survey using the newly commissioned High Efficiency and Resolution Multi-Element Spectrograph (HERMES) on…
Ages and metallicities of Hickson compact group galaxies
- R. Proctor, D. Forbes, A. Terlevich
- Physics
- 8 January 2004
ABSTRACT Hickson Compact Groups (HCGs) constitute an interesting extreme in the range ofenvironments in which galaxies are located, as the space density of galaxies in thesesmall groups are otherwise…
A MAD view of Trumpler 14
We present adaptive optics (AO) near-infrared observations of the core of the Tr 14 cluster in the Carina region obtained with the ESO multi-conjugate AO demonstrator, MAD. Our campaign yields…
An extreme paucity of second population AGB stars in the ‘normal’ globular cluster M4
- B. MacLean, S. Campbell, Y. Momany
- Physics
- 18 April 2016
Galactic Globular clusters (GCs) are now known to harbour multiple stellar populations, which are chemically distinct in many light element abundances. It is becoming increasingly clear that…
Search for associations containing young stars: chemical tagging IC 2391 and the Argus association
- G. D. Silva, V. D’Orazi, M. Sterzik
- Physics
- 25 January 2013
We explore the possible connection between the open cluster IC 2391 and the unbound Argus association identified by the SACY survey. In addition to common kinematics and ages between these two…
The GALAH survey: properties of the Galactic disc(s) in the solar neighbourhood
- L. Duong, K. Freeman, Unsw
- Physics
- 4 January 2018
Using data from the GALAH pilot survey, we determine properties of the Galactic thin and thick discs near the solar neighbourhood. The data cover a small range of Galactocentric radius (7.9 ≲ R_GC ≲…
High-resolution elemental abundance analysis of the Hyades supercluster
- G. D. Silva, K. Freeman, J. Bland-Hawthorn, M. Asplund, M. Williams, J. Holmberg
- Physics
- 14 March 2011
The existence of a kinematically defined moving group of stars centred at U = ―40, V = -17 km s ―1 , referred to as the Hyades supercluster, has been suggested to be the debris of an originally large…
Binary open clusters in the Milky Way: photometric and spectroscopic analysis of NGC 5617 and Trumpler 22
- G. D. Silva, G. Carraro, L. Rizzo
- Physics
- 12 July 2015
Using photometry and high resolution spectroscopy we investigate for the first time the physical connection between the open clusters NGC 5617 and Trumpler 22. Based on new CCD photometry we report…
