ثبت نشده
چکیده
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. We point out that the Magellanic Stream will fall into the Galaxy, and will be finally accreted by the Galactic disk. The accretion may cause warping of the inner gas disk of the Galaxy. Some clouds are accreted by the nuclear disk, which could explain the peculiar distribution and kinematics in the central region. The stripping of the interstellar gas from the Magellanic Clouds will rapidly change their morphological type into dwarf ellipticals.

New additional equations for the Newtonian dynamical systems on Riemannian manifolds are found. They supplement the previously found weak normality conditions up to the complete normality conditions for Newtonian dynamical systems.

Multi-epoch VLBA observations of the maser in NGC 4258 have yielded a 4% geometrical distance to the galaxy. The potential scientific payoffs of finding similar objects at large distances, in the Hubble flow, are considerable. In this contribution, I discuss the plausibility of detecting high-redshift water masers, and describe a search strategy that we have implemented to realize this objective.
