Star Formation in Red Spiral Galaxies (#98)

It is often assumed that red galaxies have effectively stopped forming stars and grow mostly via merging with other galaxies. However, the presence of massive red spiral galaxies in the nearby Universe (e.g., Bonne et al., in prep.) suggests this picture may be flawed. These galaxies cannot be produced by simply truncating star-formation in present-day blue spiral galaxies. We have used SDSS, 2MASS, WISE and NVSS to identify nearby galaxies with very low star formation rates and determine the environments in which these galaxies reside. Using archival 21-cm data, we have determined if these galaxies could rekindle their star formation or if star formation has been permanently truncated.
