Abstract
Understanding the continuing accretion of gas and subsequent star formation in spiral galaxies is one of the main goals of galaxy formation. We have used an advanced structure finding algorithm to identify HI halo clouds around the Milky Way. The HI gas of the Milky Way is also identified in this process. We study the structures found in two data sets, the Lieden/Argentina/Bonn survey and the Galactic All Sky Survey, to estimate the uncertainties in cloud properties. The algorithm used identifies structure hierarchically, so when going to higher resolution data, we can recover the same structure instead of breaking it up into different objects. We thus present a robust catalogue of Milky Way halo clouds and their properties.
