Ionized and neutral gas in the XUV discs of nearby spiral galaxies
We are conducting a multiwavelength study of XUV discs in nearby, gas-rich spiral galaxies combining the available UV (GALEX) observations with H i data...
Ionizing the Diffuse Interstellar Medium in Late-type Galaxies
We show how the clumpy structure of the interstellar medium (ISM) both inside HII regions and in the diffuse component, permits the propagation of ionizing...
