TL;DR: A precise measurement of the clustering of superclusters of galaxies using the redshifts of more than 141,000 galaxies from the 2dF galaxy redshift survey is reported, which favours a low-density Universe with Ω ≈ 0.3.

Simpson,Dennis Stello,Yuan-Sen Ting,Gregor Traven,Fred G. Watson,Robert A. Wittenmyer,David Yong,M. Žerjal +50 more
TL;DR: 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 the Anglo-Australian Telescope as discussed by the authors.
Journal ArticleDOI
The 2dF Galaxy Redshift Survey: The bias of galaxies and the density of the Universe
Licia Verde,Licia Verde,Alan Heavens,Will J. Percival,Sabino Matarrese,Carlton M. Baugh,Joss Bland-Hawthorn,Terry J. Bridges,Russell D. Cannon,Shaun Cole,Matthew Colless,Chris A. Collins,Warrick J. Couch,Gavin Dalton,Roberto De Propris,Simon P. Driver,George Efstathiou,Richard S. Ellis,Carlos S. Frenk,Karl Glazebrook,Carole Jackson,Ofer Lahav,Ian Lewis,Stuart Lumsden,Stephen J. Maddox,Darren Madgwick,Peder Norberg,John A. Peacock,Bruce A. Peterson,William J. Sutherland,Keith Taylor +30 more
TL;DR: In this article, the bias parameter of the 2dFGRS data set was used to measure the strength of clustering of the galaxies relative to the mass in the universe, and it was shown that on large scales, optically selected galaxies do indeed trace the underlying mass distribution.
Journal ArticleDOI
The Sydney-AAO Multi-object Integral field spectrograph
Scott M. Croom,Jon Lawrence,Jon Lawrence,Joss Bland-Hawthorn,Julia J. Bryant,L. M. R. Fogarty,Samuel N. Richards,Michael Goodwin,Tony Farrell,Stan Miziarski,Ron Heald,D. Heath Jones,Steve Lee,Matthew Colless,Sarah Brough,Andrew M. Hopkins,Amanda E. Bauer,Michael N. Birchall,Simon Ellis,Anthony Horton,Sergio G. Leon-Saval,Geraint F. Lewis,Angel R. Lopez-Sanchez,Angel R. Lopez-Sanchez,Seong-sik Min,Christopher Q. Trinh,Holly E. Trowland +26 more
TL;DR: In this paper, the authors demonstrate a novel technology that combines the power of the multi-object spectrograph with the spatial multiplex advantage of an integral field spectrogram (IFS).
Journal ArticleDOI
The RAVE survey: constraining the local Galactic escape speed
Martin C. Smith,Gregory R. Ruchti,Amina Helmi,Rosemary F. G. Wyse,Jon P. Fulbright,Kenneth C. Freeman,Julio F. Navarro,George M. Seabroke,Matthias Steinmetz,Mary E K Williams,Olivier Bienaymé,James Binney,Joss Bland-Hawthorn,Walter Dehnen,Brad K. Gibson,Gerard Gilmore,Eva K. Grebel,Ulisse Munari,Quentin A. Parker,R.-D. Scholz,Arnaud Siebert,Fred G. Watson,Tomaž Zwitter +22 more
TL;DR: In this paper, the authors used cosmological simulations of disc galaxy formation to motivate their assumptions on the shape of the velocity distribution, allowing for a significantly more precise measurement of the escape velocity compared to previous studies.
