Geometrodynamical Distances to the Galaxy's Hydrogen Streams [PDF]

, 2007
We present a geometrodynamical method for determining distances to orbital streams of HI gas in the Galaxy. The method makes use of our offset from the Galactic centre and assumes that the gas comprising the stream nearly follows a planar orbit about the Galactic centre.

Magellanic Stream: A Possible Tool for Studying Dark Halo Model [PDF]

arXiv, 2005
We model the dynamics of Magellanic Stream with the ram-pressure scenario in the logarithmic and power-law galactic halo models and construct numerically the past orbital history of Magellanic clouds and Magellanic Stream. The parameters of models include the asymptotic rotation velocity of spiral arms, halo flattening, core radius and rising or ...

The Fate of the Magellanic Stream [PDF]

arXiv, 1994
We show that HI clouds in the Magellanic Clouds are stripped by the ram-pressure due to the halo and disk gases of the Galaxy. Molecular clouds are swept to the edge of the LMC, showing an eccentric distribution. The stripped HI clouds form a narrow band on the sky, and mimics the Magellanic Stream, when the LMC takes a polar orbit.

Accretion History of the Milky Way Dark Matter Halo and the Origin of its Angular Momentum [PDF]

arXiv, 2014
The flow of dark matter into the Milky Way and Large Magellanic Cloud in a model for the gravitational field of the neighboring galaxies yields a growth history for the dark matter halo of the Milky Way that ends up with angular momentum roughly in the observed direction, and it produces a dark matter stream around the Large Magellanic Cloud that ...

New HI Features of the Magellanic System [PDF]

arXiv, 1998
The first results from the HI Parkes All-Sky Survey (HIPASS) provide a spectacular view of the global HI distribution in the vicinity of the Magellanic Clouds and the southern Milky Way. A 2400 square degree mosaic around the South Celestial Pole (SCP) reveals the existence of a narrow, continuous counter-stream which 'leads' the direction of motion of
