Blue early-type galaxies in Galaxy Zoo
Listed in IVOA Registry (Virtual Observatory)
We report the discovery of a population of nearby, blue early-type galaxies with high star formation rates (0.5<SFR<50M_{sun}_/yr).
Description
They are identified by their visual morphology as provided by Galaxy Zoo for Sloan Digital Sky Survey Data Release 6 and their u-r colour. We select a volume-limited sample in the redshift range 0.02<z<0.05, corresponding to luminosities of approximately L* and above and with u-r colours significantly bluer than the red sequence.
We confirm the early-type morphology of the objects in this sample and investigate their environmental dependence and star formation properties.
