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…
APOGEE Chemical Abundances of Globular Cluster Giants in the Inner Galaxy
Ricardo P. Schiavon, Jennifer A. Johnson, Peter M. Frinchaboy +27
We report chemical abundances obtained by SDSS-III/APOGEE for giant stars in five globular clusters located within 2.2 kpc of the Galactic centre. We detect the presence of multipl…
A broad perspective on multiple abundance populations in the globular cluster NGC 1851
Jeffrey D. Simpson, Sarah L. Martell, Colin A. Navin
We present an analysis of the multiple stellar populations of the globular cluster NGC 1851. We used lower resolution spectra of giant stars to measure CN, CH, and calcium H & K sp…
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…
New halo stars of the Galactic globular clusters M3 and M13 in the LAMOST DR1 Catalog
Colin A. Navin, Sarah L. Martell, Daniel B. Zucker
M3 and M13 are Galactic globular clusters with previous reports of surrounding stellar halos. We present the results of a search for members and extratidal cluster halo stars withi…
