The fine-scale structure of the neutral interstellar medium in nearby galaxies
(2011)
We present an analysis of the properties of H I holes detected in 20 galaxies that are part of "The H I Nearby Galaxy Survey." We detected more than 1000 holes in total in the sampled galaxies. Where they can be measured, ...
A constant molecular gas depletion time in nearby disk galaxies
(2011)
We combine new sensitive, wide-field CO data from the HERACLES survey with ultraviolet and infrared data from GALEX and Spitzer to compare the surface densities of H2, ΣH2, and the recent star formation rate, ΣSFR, over ...
A molecular star formation law in the atomic-gas-dominated regime in nearby galaxies
(2011)
We use the IRAM HERACLES survey to study CO emission from 33 nearby spiral galaxies down to very low intensities. Using 21 cm line atomic hydrogen (H I) data, mostly from THINGS, we predict the local mean CO velocity based ...
