On class visualisation for high dimensional data: Exploring scientific datasets
Ata Kaban, Jianyong Sun, Somak Raychaudhury +1
Parametric Embedding (PE) has recently been proposed as a general-purpose algorithm for class visualisation. It takes class posteriors produced by a mixture-based clustering algori…
Young stellar populations in early-type galaxies in the Sloan Digital Sky Survey
Louisa A. Nolan, Somak Raychaudhury, Ata Kaban
We use a purely data-driven rectified factor analysis to identify early-type galaxies with recent star formation in DR4 of the SDSS Spectroscopic Catalogue. We compare the spectra…
The star-formation histories of elliptical galaxies across the fundamental plane
Louisa A. Nolan, J. S. Dunlop, B. Panter +3
We present the first results from a study designed to test whether, given high-quality spectrophotometry spanning the mid-UV--optical wavelength regime, it is possible to distingui…
