Geometrodynamical Distances to the Galaxy's Hydrogen Streams
Shoko Jin, Donald Lynden-Bell
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…
Analytic Central Orbits and their Transformation Group
Donald Lynden-Bell, Shoko Jin
A useful crude approximation for Abelian functions is developed and applied to orbits. The bound orbits in the power-law potentials A*r^{-alpha} take the simple form (l/r)^k = 1 +…
Are Complex A and the Orphan Stream related?
Shoko Jin, D. Lynden-Bell
We consider the possibility that the Galactic neutral hydrogen stream Complex A and the stellar Orphan stream are related, and use this hypothesis to determine possible distances t…
Massive Black Holes in Dwarf Spheroidal Galaxy Haloes?
Shoko Jin, Jeremiah P. Ostriker, Mark I. Wilkinson
It is now established that several of the Local Group dwarf Spheroidal galaxies (dSphs) have large mass-to-light ratios. We consider the possibility that the dark matter in the hal…
