The HI Halo of Spiral Galaxies

Astrophysics and Space Science, 2004
A deep H I survey with the VLA of the spiral galaxy NGC 2403 has revealed the existence of a thick, low density layer of neutral gas surrounding the thin 'cold' disk. This layer has a mean rotation velocity 25-50 km s(-1) lower than that of the disk and a 10-20 km s(-1) inflow towards the centre of the galaxy.

The Rotation of Spiral Galaxies

Science, 1983
There is accumulating evidence that as much as 90 percent of the mass of the universe is nonluminous and is clumped, halo-like, around individual galaxies. The gravitational force of this dark matter is presumed to be responsible for the high rotational velocities of stars and gas in the disks of spiral galaxies.

Spirals in galaxies

Proceedings of the International Astronomical Union, 2019
AbstractThe venerable problem of what causes the spiral features in disk galaxies is nearing a solution. In previous work, we have shown that transient spirals in simulations result from the superposition of a few coherent waves that have many properties of modes.

DYNAMICS OF SPIRAL GALAXIES

Frontiers of Applied Mathematics, 2007
The dynamics of spiral galaxies is a gold-mine of challenging problems for the astrophysicist and the applied mathematician. In Astrophysics, we may ask how these island-universes formed, evolved, and reached their current structure and thus address the problems of the dynamics of the interstellar medium, of star formation, of stellar dynamics, and of ...

Dark matter in spiral galaxies

Philosophical Transactions of the Royal Society of London. Series A, Mathematical and Physical Sciences, 1986
Abstract Mass models of spiral galaxies based on the observed light distribution, assuming constant M /L for bulge and disc, are able to reproduce the observed rotation curves in the inner regions, but fail to do so increasingly towards and beyond the edge of the visible material.
