Galaxy And Mass Assembly (GAMA): mass-size relations of z0.1 galaxies subdivided by Sérsic index, colour and morphology
Rebecca Lange, Simon P. Driver, Aaron S. G. Robotham +20
We use data from the Galaxy And Mass Assembly (GAMA) survey in the redshift range 0.01z0.1 (8399 galaxies in to bands) to derive the stellar mass half-light rad…
OMEGA: OSIRIS Mapping of Emission-Line Galaxies in A901/2
Bruno Rodriguez Del Pino, Ana L. Chies-Santos, Alfonso Aragon-Salamanca +2
This work presents the first results from an ESO Large Programme carried out using the OSIRIS instrument on the 10m GTC telescope (La Palma). We have observed a large sample of gal…
Galaxy And Mass Assembly (GAMA): Refining the Local Galaxy Merger Rate using Morphological Information
Kevin R. V. Casteels, Christopher J. Conselice, Steven P. Bamford +16
We use the Galaxy And Mass Assembly (GAMA) survey to measure the local Universe mass dependent merger fraction and merger rate using galaxy pairs and the CAS structural method, whi…
Galaxy Zoo: CANDELS Barred Disks and Bar Fractions
B. D. Simmons, Thomas Melvin, Chris Lintott +39
The formation of bars in disk galaxies is a tracer of the dynamical maturity of the population. Previous studies have found that the incidence of bars in disks decreases from the l…
Galaxy Zoo: Are Bars Responsible for the Feeding of Active Galactic Nuclei at 0.2 < z < 1.0?
Edmond Cheung, Jonathan R. Trump, E. Athanassoula +19
We present a new study investigating whether active galactic nuclei (AGN) beyond the local universe are preferentially fed via large-scale bars. Our investigation combines data fro…
MegaMorph -- multi-wavelength measurement of galaxy structure: physically meaningful bulge-disc decomposition of galaxies near and far
Marina Vika, Steven P. Bamford, Boris Häußler +1
Bulge-disc decomposition is a valuable tool for understanding galaxies. However, achieving robust measurements of component properties is difficult, even with high quality imaging,…
