HI shells in the Leiden/Argentina/Bonn HI survey.

EHLEROVA S. and PALOUS J.

Abstract (from CDS):

We analyse the all-sky Leiden/Argentina/Bonn HI survey, where we identify shells belonging to the Milky Way. We used an identification method based on the search of continuous regions of a low brightness temperature that are compatible with given properties of HI shells. We found 333 shells in the whole Galaxy. The size distribution of shells in the outer Galaxy is fitted by a power law with the coefficient of 2.6 corresponding to the index 1.8 in the distribution of energy sources. Their surface density decreases exponentially with a scale length of 2.8kpc. The surface density of shells with radii ≥100pc in the solar neighbourhood is ∼4kpc–2 and the 2D porosity is ∼0.7.
