Galaxy Cluster Mass Reconstruction Project: III. The impact of dynamical substructure on cluster mass estimates (2017)
Journal Article

With the advent of wide-field cosmological surveys, we are approaching samples of hundreds of thousands of galaxy clusters. While such large numbers will help reduce statistical uncertainties, the control of systematics in cluster masses is crucial.... Read More about Galaxy Cluster Mass Reconstruction Project: III. The impact of dynamical substructure on cluster mass estimates.

Galaxy And Mass Assembly: the G02 field, Herschel–ATLAS target selection and data release 3 (2017)
Journal Article

We describe data release 3 (DR3) of the Galaxy And Mass Assembly (GAMA) survey. The GAMA survey is a spectroscopic redshift and multiwavelength photometric survey in three equatorial regions each of 60.0 deg2 (G09, G12, and G15), and two southern reg...

Galaxy Zoo: secular evolution of barred galaxies from structural decomposition of multiband images (2017)
Journal Article

We present the results of two-component (disc+bar) and three-component (disc+bar+bulge) multiwavelength 2D photometric decompositions of barred galaxies in five Sloan Digital Sky Survey (SDSS) bands (ugriz). This sample of ?3500 nearby (z

Galaxy Zoo and SPARCFIRE: constraints on spiral arm formation mechanisms from spiral arm number and pitch angles (2017)
Journal Article

In this paper, we study the morphological properties of spiral galaxies, including measurements of spiral arm number and pitch angle. Using Galaxy Zoo 2, a stellar mass-complete sample of 6222 SDSS spiral galaxies is selected. We use the machine visi...

The effects of the cluster environment on the galaxy mass-size relation in MACS J1206.2-0847 (2017)
Journal Article

The dense environment of galaxy clusters strongly influences the nature of galaxies. Their abundance and diversity is imprinted on the stellar-mass–size plane. Here, we study the cause of the size distribution of a sample of 560 spectroscopic members...

Comparing experts and novices in Martian surface feature change detection and identification (2017)
Journal Article

Change detection in satellite images is a key concern of the Earth Observation field for environmental and climate change monitoring. Satellite images also provide important clues to both the past and present surface conditions of other planets, whic...

Galaxy Zoo: finding offset discs and bars in SDSS galaxies (2017)
Journal Article

We use multiwavelength Sloan Digital Sky Survey (SDSS) images and Galaxy Zoo morphologies to identify a sample of ∼270 late-type galaxies with an off-centre bar. We measure offsets in the range 0.2–2.5 kpc between the photometric centres of the stell... Read More about Galaxy Zoo: finding offset discs and bars in SDSS galaxies.

Task Workflow Design and its impact on performance and volunteers' subjective preference in Virtual Citizen Science (2017)
Journal Article

© 2017 The Authors Virtual citizen science platforms allow non-scientists to take part in scientific research across a range of disciplines. What they ask of volunteers varies considerably in terms of task type, variety, user judgement required and u...

Galaxy Zoo: star formation versus spiral arm number (2017)
Journal Article

Spiral arms are common features in low-redshift disc galaxies, and are prominent sites of star formation and dust obscuration. However, spiral structure can take many forms: from galaxies displaying two strong ‘grand design’ arms to those with many ‘... Read More about Galaxy Zoo: star formation versus spiral arm number.

OMEGA – OSIRIS Mapping of Emission-line Galaxies in A901/2: II. Environmental influence on integrated star formation properties and AGN activity (2017)
Journal Article

We present a study of the star formation and AGN activity for galaxies in CP 15051 the Abell 901/2 multicluster system at z ∼ 0.167 as part of the OSIRIS Mapping of Emission-line Galaxies in A901/2 (OMEGA) survey. Using Tuneable Filter data obtained... Read More about OMEGA – OSIRIS Mapping of Emission-line Galaxies in A901/2: II. Environmental influence on integrated star formation properties and AGN activity.
