The Galah Survey: Classification and diagnostics with t-SNE reduction of spectral information
G. Traven, G. Matijevič, T. Zwitter +24
Galah is an ongoing high-resolution spectroscopic survey with the goal of disentangling the formation history of the Milky Way, using the fossil remnants of disrupted star formatio…
The GALAH Survey: Observational Overview and Gaia DR1 companion
Sarah Martell, Sanjib Sharma, Sven Buder +30
The Galactic Archaeology with HERMES (GALAH) Survey is a massive observational project to trace the Milky Way's history of star formation, chemical enrichment, stellar migration an…
The GALAH survey: The data reduction pipeline
Janez Kos, Jane Lin, Tomaž Zwitter +29
We present the data reduction procedures being used by the GALAH survey, carried out with the HERMES fibre-fed, multi-object spectrograph on the 3.9~m Anglo-Australian Telescope. G…
The age-metallicity relation in the solar neighbourhood from a pilot sample of white dwarf-main sequence binaries
A. Rebassa-Mansergas, B. Anguiano, E. García-Berro +6
The age-metallicity relation (AMR) is a fundamental observational constraint for understanding how the Galactic disc formed and evolved chemically in time. However, there is not ye…
The ANU WiFeS SuperNovA Program (AWSNAP)
Michael J. Childress, Brad E. Tucker, Fang Yuan +24
This paper presents the first major data release and survey description for the ANU WiFeS SuperNovA Program (AWSNAP). AWSNAP is an ongoing supernova spectroscopy campaign utilising…
The GALAH Survey: Relative throughputs of the 2dF fibre positioner and the HERMES spectrograph from stellar targets
Jeffrey D. Simpson, G. M. De Silva, J. Bland-Hawthorn +11
We present an analysis of the relative throughputs of the 3.9-metre Anglo-Australian Telescope's 2dF/HERMES system, based upon spectra acquired during the first two years of the GA…
Identification of Globular Cluster Stars in RAVE data II: Extended tidal debris around NGC 3201
B. Anguiano, G. M. De Silva, K. Freeman +22
We report the identification of extended tidal debris potentially associated with the globular cluster NGC 3201, using the RAVE catalogue. We find the debris stars are located at a…
