Extremely inefficient star formation in the outer disks of nearby galaxies
(2010)
We combine data from The H I Nearby Galaxy Survey and the GALEX Nearby Galaxy Survey to study the relationship between atomic hydrogen (H I) and far-ultraviolet (FUV) emission outside the optical radius (r 25) in 17 spiral ...
The star formation efficiency in nearby galaxies : measuring where gas forms stars effectively
(2008)
We measure the star formation efficiency (SFE), the star formation rate (SFR) per unit of gas, in 23 nearby galaxies and compare it with expectations from proposed star formation laws and thresholds.We use Hi maps from The ...
