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…
Isophotal shapes of early-type galaxies to very faint levels
Laxmikant Chaware, Russell Cannon, Ajit K. Kembhavi +1
We report on a study of the isophotal shapes of early-type galaxies, to very faint levels reaching ~ 0.1% of the sky brightness. The galaxies are from the Large Format Camera (LFC)…
Angular correlation function of 1.5 million LRGs: clustering evolution and a search for BAO
U. Sawangwit, T. Shanks, F. B. Abdalla +5
We present the angular correlation function measured from photometric samples comprising 1,562,800 luminous red galaxies (LRGs). Three LRG samples were extracted from the Sloan Dig…
The 2dF-SDSS LRG and QSO Survey: The spectroscopic QSO catalogue
Scott M. Croom, Gordon T. Richards, Tom Shanks +27
We present the final spectroscopic QSO catalogue from the 2dF-SDSS LRG and QSO (2SLAQ) Survey. This is a deep, 18<g<21.85 (extinction corrected), sample aimed at probing in detail…
Radio galaxies in the 2SLAQ Luminous Red Galaxy survey: II. The stellar populations of radio-loud and radio-quiet LRGs
Helen M. Johnston, Elaine M. Sadler, Russell Cannon +3
We present an analysis of the optical spectra of a volume-limited sample of 375 radio galaxies at redshift 0.4<z<0.7 from the 2dF-SDSS Luminous Red Galaxy and QSO (2SLAQ) redshift…
Abundances on the Main Sequence of Omega Centauri
Laura M. Stanford, G. S. Da Costa, John E. Norris
Abundance ratios of carbon, nitrogen and strontium relative to iron, calculated using spectrum synthesis techniques, are given for a sample of main sequence and turnoff stars that…
