Abstract:
We have identified a population of passive spiral galaxies from
photometry and integral field spectroscopy. We selected z<0.035
spiral galaxies that have WISE colours consistent with little
mid-infrared emission from warm dust. Matched aperture photometry of
51 spiral galaxies in ultraviolet, optical and mid-infrared show these
galaxies have colours consistent with passive galaxies. Six galaxies
form a spectroscopic pilot study and were observed using the
Wide-Field Spectrograph (WiFeS) to check for signs of nebular emission
from star formation. We see no evidence of substantial nebular
emission found in previous red spiral samples. These six galaxies
possess absorption line spectra with 4000Å breaks consistent with an
average luminosity-weighted age of 2.3Gyr. Our photometric and IFU
spectroscopic observations confirm the existence of a population of
local passive spiral galaxies, implying that transformation into
early-type morphologies is not required for the quenching of star
formation.
