The SLUGGS survey: chromodynamical modelling of the lenticular galaxy NGC 1023 (2015)
Journal Article

Globular clusters (GCs) can be considered discrete, long-lived, dynamical tracers that retain crucial information about the assembly history of their parent galaxy. In this paper, we present a new catalogue of GC velocities and colours for the lentic... Read More about The SLUGGS survey: chromodynamical modelling of the lenticular galaxy NGC 1023.

Galaxy And Mass Assembly (GAMA): Panchromatic Data Release (far-UV–far-IR) and the low-zenergy budget (2015)
Journal Article

We present the Galaxy And Mass Assembly (GAMA) Panchromatic Data Release (PDR) constituting over 230 deg2 of imaging with photometry in 21 bands extending from the far-UV to the far-IR. These data complement our spectroscopic campaign of over 300k ga... Read More about Galaxy And Mass Assembly (GAMA): Panchromatic Data Release (far-UV–far-IR) and the low-zenergy budget.

Wavelength self-calibration and sky subtraction for Fabry–Pérot interferometers: applications to OSIRIS (2015)
Journal Article

We describe techniques concerning wavelength calibration and sky subtraction to maximize the scientific utility of data from tunable filter instruments. While we specifically address data from the Optical System for Imaging and low Resolution Integra...

Galaxy And Mass Assembly (GAMA): the wavelength dependence of galaxy structure versus redshift and luminosity (2015)
Journal Article

We study how the sizes and radial profiles of galaxies vary with wavelength, by fitting Sersic functions simultaneously to imaging in nine optical and near-infrared bands. To quantify the wavelength dependence of effective radius we use the ratio, R,...

Galaxy And Mass Assembly (GAMA): end of survey report and data release 2 (2015)
Journal Article

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 limiting magnitude of r < 19.8 mag, we have collect...

OMEGA - OSIRIS Mapping of Emission-line Galaxies in A901/2: I. Survey description, data analysis, and star formation and AGN activity in the highest density regions (2015)
Journal Article

We present an overview of and first results from the OMEGA (OSIRIS Mapping of Emission-line Galaxies in the multicluster system A901/2) survey. The ultimate goal of this project is to study star formation and active galactic nucleus (AGN) activity ac... Read More about OMEGA - OSIRIS Mapping of Emission-line Galaxies in A901/2: I. Survey description, data analysis, and star formation and AGN activity in the highest density regions.

Galaxy And Mass Assembly (GAMA): mass-size relations of z < 0.1 galaxies subdivided by Sersic index, colour and morphology (2015)
Journal Article

© 2015 The Authors. We use data from the Galaxy And Mass Assembly (GAMA) survey in the redshift range 0.01 < z < 0.1 (8399 galaxies in g to Ks bands) to derive the stellar mass-half-light radius relations for various divisions of 'early'- and 'late'-...

MegaMorph - multiwavelength measurement of galaxy structure: physically meaningful bulge-disc decomposition of galaxies near and far (2014)
Journal Article

Bulge–disc decomposition is a valuable tool for understanding galaxies. However, achieving robust measurements of component properties is difficult, even with high-quality imaging, and it becomes even more so with the imaging typical of large surveys...

Galaxy And Mass Assembly (GAMA): the wavelength-dependent sizes and profiles of galaxies revealed by MegaMorph (2014)
Journal Article

We investigate the relationship between colour and structure within galaxies using a large, volume-limited sample of bright, low-redshift galaxies with optical–near-infrared imaging from the Galaxy And Mass Assembly survey. We fit single-component, w... Read More about Galaxy And Mass Assembly (GAMA): the wavelength-dependent sizes and profiles of galaxies revealed by MegaMorph.

Caught in the act: cluster 'k+a' galaxies as a link between spirals and S0s (2014)
Journal Article

We use integral field spectroscopy of 13 disc galaxies in the cluster AC114 at z ∼ 0.31 in an attempt to disentangle the physical processes responsible for the transformation of spiral galaxies in clusters. Our sample is selected to display a dominan... Read More about Caught in the act: cluster 'k+a' galaxies as a link between spirals and S0s.

Galaxy Zoo 1 : Data Release of Morphological Classifications for nearly 900,000 galaxies (2010)
Journal Article

Morphology is a powerful indicator of a galaxy's dynamical and merger history. It is strongly correlated with many physical parameters, including mass, star formation history and the distribution of mass. The Galaxy Zoo project collected simple morph...

Galaxy Zoo: A correlation between coherence of galaxy spin chirality and star formation efficiency (2010)
Journal Article

We report on the finding of a correlation between galaxies' past star formation activity and the degree to which neighbouring galaxies rotation axes are aligned. This is obtained by cross-correlating star formation histories, derived with MOPED, and...

Galaxy Zoo: Chiral correlation function of galaxy spins (2009)
Journal Article

Galaxy Zoo is the first study of nearby galaxies that contains reliable information about the spiral sense of rotation of galaxy arms for a sizeable number of galaxies. We measure the correlation function of spin chirality (the sense in which galaxie... Read More about Galaxy Zoo: Chiral correlation function of galaxy spins.
