- catalog abstract "Warm ionized hydrogen is widespread in our Galaxy, but not well understood, challenging the traditional picture of the interstellar medium, including the morphology of the medium and the mechanisms of ionization and heating. The Wisconsin H-alpha Mapper (WHAM) facility is studying this gas through observations of faint optical emission lines at high spectral resolution, and has completed a northern sky survey of the interstellar H-alpha emission giving a picture of distribution and kinematics of the difuse ionized hydrogen trough the H-alpha line.".
