Galaxy and mass assembly (GAMA): End of survey report and data release 2
The Galaxy And Mass Assembly (GAMA) survey is one of the largest contemporary spectroscopic surveys of low redshift galaxies. Covering an area of ∼286 deg2 (split among five survey regions) down to a…
The SAMI Galaxy Survey: Instrument specification and target selection
- J. Bryant, M. Owers, C. Walcher
- Physics
- 28 July 2014
The SAMI Galaxy Survey will observe 3400 galaxies with the Sydney-AAO Multi- object Integral-field spectrograph (SAMI) on the Anglo-Australian Telescope (AAT) in a 3-year survey which began in 2013.…
The SLUGGS Survey: Calcium Triplet-based Spectroscopic Metallicities for Over 900 Globular Clusters
Although the colour distribution of globular clusters in massive galaxies is well known to be bimodal, the spectroscopic metallicity distribution has been measured in only a few galaxies. After…
Galaxy and mass assembly (GAMA): A deeper view of the mass, metallicity and SFR relationships
- M. Lara-López, A. Hopkins, D. Thomas
- Physics
- 7 June 2013
A full appreciation of the role played by gas metallicity (Z), star formation rate (SFR) and stellar mass (M*) is fundamental to understanding how galaxies form and evolve. The connections between…
Galaxy And Mass Assembly: evolution of the Hα luminosity function and star formation rate density up to z < 0.35
- M. Gunawardhana, A. Hopkins, L. Wang
- Physics
- 23 May 2013
Measurements of the low-z H alpha luminosity function, Phi, have a large dispersion in the local number density of sources (similar to 0.5-1 Mpc(-3) dex(-1)), and correspondingly in the star…
Galaxy And Mass Assembly (GAMA): deconstructing bimodality – I. Red ones and blue ones
- E. Taylor, A. Hopkins, J. Loveday
- Physics
- 26 August 2014
We measure the mass functions for generically red and blue galaxies, using a z 8.7 field galaxies from the Galaxy And Mass Assembly (GAMA) survey. Our motivation is that, as we show, the dominant…
Galaxy And Mass Assembly (GAMA): Linking Star Formation Histories and Stellar Mass Growth
- A. Bauer, A. Hopkins, R. Sharp
- Physics
- 11 June 2013
We present evidence for stochastic star formation histories in low-mass (M* < 1010 M⊙) galaxies from observations within the Galaxy And Mass Assembly (GAMA) survey. For ˜73 000 galaxies between 0.05…
The Aspen-Amsterdam void finder comparison project
- J. Colberg, F. Pearce, D. University
- Physics
- 6 March 2008
Despite a history that dates back at least a quarter of a century studies of voids in the large–scale structure of the Universe are bedevilled by a major problem: there exist a large number of quite…
THE SLUGGS SURVEY: WIDE-FIELD STELLAR KINEMATICS OF EARLY-TYPE GALAXIES
- J. Arnold, A. Romanowsky, K. Woodley
- Physics
- 9 October 2013
We present stellar kinematics of 22 nearby early-type galaxies (ETGs), based on two-dimensional (2D) absorption line stellar spectroscopy out to ∼2–4 Re (effective radii), as part of the ongoing…
SMALL SCATTER AND NEARLY ISOTHERMAL MASS PROFILES TO FOUR HALF-LIGHT RADII FROM TWO-DIMENSIONAL STELLAR DYNAMICS OF EARLY-TYPE GALAXIES
- M. Cappellari, A. Romanowsky, J. Arnold
- Physics
- 1 April 2015
We study the total mass–density profile for a sample of 14 fast-rotator early-type galaxies (stellar masses 10.2 ≲ log M * / M ⊙ ≲ 11.7 ?> ). We combine observations from the SLUGGS and ATLAS 3 D ?>…
