Galaxy And Mass Assembly (GAMA): the wavelength dependence of galaxy structure versus redshift and luminosity by Kennedy, Rebecca, Bamford, Steven P., Baldry, Ivan, Häußler, Boris, Holwerda, Benne W., Hopkins, Andrew M., Kelvin, Lee S., Lange, Rebecca, Moffett, Amanda J., Popescu, Cristina C., Taylor, Edward N., Tuffs, Richard J., Vika, Marina, Vulcani, Benedetta

“…Vulcani et al. have demonstrated that different galaxy populations present sharply contrasting behaviour in terms of R and N. Here we study the luminosity dependence of this result. We find that at higher luminosities, early-type galaxies display a more substantial decrease in effective radius with wavelength, whereas late types present a more pronounced increase in Sersic index. …”

Galaxy And Mass Assembly (GAMA): galaxy colour gradients versus colour, structure, and luminosity by Kennedy, Rebecca, Bamford, Steven P., Häußler, Boris, Brough, Sarah, Holwerda, Benne, Hopkins, Andrew M., Vika, Marina, Vulcani, Benedetta

“…We find a bimodality in the colour gradients of high- and low-n galaxies in all wavebands which varies with overall galaxy luminosity. Global trends in colour gradients therefore result from combining the contrasting behaviour of a number of different galaxy populations. …”

“…Thus far, these combined observations have only covered one order of magnitude in radio and X-ray luminosity range; this means that any potential radio-X-ray luminosity correlation, LR ∝ LXβ, is not well constrained (β ≈ 0.4-0.9, based on various studies) or understood. …”
