S0 galaxies are often thought to be passively evolved from spirals after star formation is quenched. To explore what is actually occurring in such galaxies, we present a multi-wavelength case study of...
A Search for Young Stars in the S0 Galaxies of a Super-Group at z=0.37
Search S0 Galaxies Super-Group z=0.37
2011/10/12
We analyze GALEX UV data for a system of four gravitationally-bound groups at z=0.37, SG1120, which is destined to merge into a Coma-mass cluster by z=0, to study how galaxy properties may change duri...
The Relationship Between Molecular Gas and Star Formation in Low-Mass E/S0 Galaxies
Relationship Between Molecular Gas Star Formation
2010/11/11
We consider the relationship between molecular-gas and star-formation sur-face densities in 19 morphologically defined E/S0s with stellar mass . 4 × 1010M⊙, paying particular attention to those found ...
Stellar Population Trends in S0 Galaxies
Cosmology and Extragalactic Astrophysics (astro-ph.CO)
2010/12/27
We present stellar population age and metallicity trends for a sample of 59 S0 galaxies based on optical SDSS and NIR J & H photometry. When combined with optical g and r passband imaging data from th...
