Deep Hα survey of the Milky Way

The detailed velocity field of the ionized hydrogen has been observed between l = 3010 and l = 3240 as part of an Hα Survey of the southern Milky Way. Analysis of the Hα profiles shows six different velocity components. These Hα observations, combined with multiwavelength and stellar data, are used...

Summary:The detailed velocity field of the ionized hydrogen has been observed between l = 3010 and l = 3240 as part of an Hα Survey of the southern Milky Way. Analysis of the Hα profiles shows six different velocity components. These Hα observations, combined with multiwavelength and stellar data, are used to find the most probable distances of the different gas layers.
Bibliography:Based on observations collected at the European Southern Observatory.
