Secularly powered outflows from AGN: the dominance of non-merger driven supermassive black hole growth
Rebecca Smethurst, Brooke Simmons, Chris Lintott +1
Recent observations and simulations have revealed the dominance of secular processes over mergers in driving the growth of both supermassive black holes (SMBH) and galaxy evolution…
SDSS-IV MaNGA: Stellar Population Gradients Within Barred Galaxies
Amelia Fraser-McKelvie, Michael Merrifield, Alfonso Aragón-Salamanca +11
Bars in galaxies are thought to stimulate both inflow of material and radial mixing along them. Observational evidence for this mixing has been inconclusive so far however, limitin…
Galaxy Zoo: Probabilistic Morphology through Bayesian CNNs and Active Learning
Mike Walmsley, Lewis Smith, Chris Lintott +10
We use Bayesian convolutional neural networks and a novel generative model of Galaxy Zoo volunteer responses to infer posteriors for the visual morphology of galaxies. Bayesian CNN…
Galaxy Zoo: Unwinding the Winding Problem - Observations of Spiral Bulge Prominence and Arm Pitch Angles Suggest Local Spiral Galaxies are Winding
Karen L. Masters, Chris J. Lintott, Ross E. Hart +8
We use classifications provided by citizen scientists though Galaxy Zoo to investigate the correlation between bulge size and arm winding in spiral galaxies. Whilst the traditional…
SDSS IV MaNGA: Full spectroscopic bulge-disc decomposition of MaNGA early-type galaxies
Martha Tabor, Michael Merrifield, Alfonso Aragon-Salamanca +5
By applying spectroscopic decomposition methods to a sample of MaNGA early-type galaxies, we separate out spatially and kinematically distinct stellar populations, allowing us to e…
SNITCH: Seeking a simple, informative star formation history inference tool
R. J. Smethurst, M. Merrifield, C. J. Lintott +7
Deriving a simple, analytic galaxy star formation history (SFH) using observational data is a complex task without the proper tool to hand. We therefore present SNITCH, an open sou…
