The warm and dense Galaxy - tracing the formation of dense cloud structures out to the Galactic Center
Thomas Stanke, Henrik Beuther, Jens Kauffmann +11

The 2dF Galaxy Redshift Survey: The blue galaxy fraction and implications for the Butcher-Oemler effect

The 2dF Galaxy Redshift Survey: Final Data Release
Matthew Colless, Bruce A. Peterson, Carole Jackson +25
The 2dF Galaxy Redshift Survey (2dFGRS) has obtained spectra for 245591 sources, mainly galaxies, brighter than a nominal extinction-corrected magnitude limit of b_J=19.45. Reliabl…
Parameter constraints for flat cosmologies from CMB and 2dFGRS power spectra
Will J. Percival, Will Sutherland, John A. Peacock +24
We constrain flat cosmological models with a joint likelihood analysis of a new compilation of data from the cosmic microwave background (CMB) and from the 2dF Galaxy Redshift Surv…
Infall and Outflow Motions towards a Sample of Massive Star Forming Regions from the RMS Survey
Nichol Cunningham, Stuart Lumsden, Toby Moore +2
We present the results of an outflow and infall survey towards a distance limited sample of 31 massive star forming regions drawn from the RMS survey. The presence of young, active…

Will J. Percival, Carlton M. Baugh, Joss Bland-Hawthorn +24
The 2dF Galaxy Redshift Survey has now measured in excess of 160000 galaxy redshifts. This paper presents the power spectrum of the galaxy distribution, calculated using a direct F…
The 2dF Galaxy Redshift Survey: The environmental dependence of galaxy star formation rates near clusters

We have measured the equivalent width of the H-alpha emission line for 11006 galaxies brighter than M_b=-19 (LCDM) at 0.05<z<0.1 in the 2dF Galaxy Redshift Survey (2dF), in the fie…
The 2dF Galaxy Redshift Survey: the local E+A galaxy population
Chris Blake, Michael Pracy, Warrick Couch +27
We select a sample of low-redshift (z ~ 0.1) E+A galaxies from the 2dF Galaxy Redshift Survey (2dFGRS). The spectra of these objects are defined by strong hydrogen Balmer absorptio…
The 2dF Galaxy Redshift Survey: Wiener Reconstruction of the Cosmic Web

The 2dF Galaxy Redshift Survey: Near Infrared Galaxy Luminosity Functions
Shaun Cole, Peder Norberg, Carlton Baugh +24
