Dynamics of Galaxies

Astronomical & Astrophysical Transactions, 2001
Our understanding of galaxies, the building blocks of the Universe has advanced significantly in recent years. New observations from ground- and space-based telescopes, the discovery of dark matter, and new insights into its distribution have been instrumental in this.

Dynamics of the Galaxy

1988
Stellar dynamics is concerned with the theoretical study of idealised stellar systems: assemblages of point masses which interact with one another according to the laws of classical mechanics and of Newtonian gravitation. The influence of the gravitational field of the interstellar matter or an external field is also taken into account when this ...

The Dynamics of Galaxies

Annual Review of Astronomy and Astrophysics, 1963
Brightness distributions, velocity dispersions, and rotation of elliptical galaxies are discussed. Gravitational forces between multiple galaxies and groups are considered. Optical rotation curves and radio observations of spiral and irregular galaxies are described. Theoretical models for the dynamics of galaxies are also discussed. (C.E.S.)

Dynamics of Elliptical Galaxies

Science, 1993
Elliptical galaxies were once thought to be similar in their structure and dynamics to rotationally flattened bodies like stars. The discovery that elliptical galaxies rotate much more slowly than a fluid body with the same shape has led to a qualitative change in our understanding of the dynamics of these systems.

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 ...

Dynamics of Galaxies and Clusters of Galaxies

2008
The purpose of these lectures is to describe some of the dynamical phenomena that are important in the evolution of galaxies and clusters of galaxies. Galactic Dynamics is usually perceived as an arid discipline, whose mathematical formalism make it hard to apply to real astronomical problems.

Our understanding of galaxies, the building blocks of the Universe has advanced significantly in recent years. New observations from ground- and space-based telescopes, the discovery of dark matter, and new insights into its distribution have been instrumental in this.

A dynamical model of the Galaxy

Astronomy Reports, 2003
A series of dynamical models of the Galaxy is constructed assuming that the entire disk is near the gravitational-stability limit. This imposes constraints on the dynamical and kinematic parameters of the main subsystems (the disk, bulge, and halo). The disk surface density in the solar neighborhood should not exceed 58 M⊙/pc2.
