Galactic HI supershells kinetic energies

DOI

We estimate the Galactic supershell (GS) masses and energies. We developed and used an automatic algorithm. The study was carried out making use of the Leiden-Argentine-Bonn (LAB) HI survey in the outer part of the Galaxy. The algorithm was applied only to a set of GSs from the catalogue of Suad et al. (2014, Cat. J/A+A/564/A116), those showing HI-emission surrounding its central cavity in at least three quarters (or 270 degrees) of its angular extent. A total of 490 GSs fulfilled this criterion. Among them, 308 are completely surrounded by walls of HI-emission (Group A) and in the remaining 182 the central HI minimum is surrounded by ridges of HI emission in at least 270{deg} of its angular extent (Group B).
