MegaMorph: classifying galaxy morphology using multi-wavelength Sérsic profile fits
M. Vika, B. Vulcani, S. P. Bamford +2
Aims. This work investigates the potential of using the wavelength-dependence of galaxy structural parameters (Sérsic index, n, and effective radius, Re) to separate galaxies into…
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,…
MegaMorph -- multi-wavelength measurement of galaxy structure: Sérsic profile fits to galaxies near and far
Marina Vika, Steven P. Bamford, Boris Haeussler +3
We demonstrate a new multi-wavelength technique for two-dimensional parametric modelling of galaxy surface-brightness profiles, which we have incorporated into the widely used soft…
MegaMorph - multi-wavelength measurement of galaxy structure: complete Sérsic profile information from modern surveys
Boris Häußler, Steven P. Bamford, Marina Vika +13
In this paper, we demonstrate a new method for fitting galaxy profiles which makes use of the full multi-wavelength data provided by modern large optical-near-infrared imaging surv…
Revealing components of the galaxy population through nonparametric techniques
Steven P. Bamford, Alex L. Rojas, Robert C. Nichol +4
The distributions of galaxy properties vary with environment, and are often multimodal, suggesting that the galaxy population may be a combination of multiple components. The behav…
