The Larson-Tinsley Effect in the UV: Interacting vs. `Normal' Spiral Galaxies
Cosmology and Extragalactic Astrophysics (astro-ph.CO)
2010/12/24
We compare the UV-optical colors of a well-defined set of optically-selected pre-merger interacting galaxy pairs with those of normal spirals. The shorter wavelength colors show a larger dispersion fo...
Arm & Interarm Star Formation in Spiral Galaxies
Cosmology and Extragalactic Astrophysics (astro-ph.CO)
2010/12/24
We investigate the relationship between spiral arms and star formation in the grand-design spirals NGC 5194 and NGC 628 and in the flocculent spiral NGC 6946.
