High Velocity Clouds

The nature of the large high velocity clouds of neutral hydrogen gas observed around our galaxy remains as one of the more enigmatic phenomena in our skies. Some have suggested that these "HVCs" are the building blocks of galaxies, while others believe that they are formed by tidal interactions between the Milky Way and the Magellanic Clouds.

I present a summary of the different theories on the origins of HVCs in the document below. I wrote this essay while on holiday in Europe, squeezing in writing sessions late at night after busy days exploring the sights with most of my research performed during the 10 flight from Seoul to Amsterdam.
