At the beginning of the XIX century one of the scientific issues driving the research of astronomers, like the Herschels, was to test if all the nebulæ can be resolved into stars. This research continued uninterruptedly for many years surveying the

A method to resolve the nuclear activity in galaxies, as applied to NGC1358

Autor: Per-Olof Lindblad, Kambiz Fathi

Nuclear regions of galaxies generally host a mixture of components with different exitation, composition, and kinematics. Derivation of emission line ratios and kinematics could then be misleading, if due correction is not made for the limited spatia

Observational Determination of the Gravitational Potential and Pattern Speed in Strongly Barred Galaxies

Autor: Per Olof Lindblad, Per A. B. Lindblad

Publikováno v: Galaxies and Chaos ISBN: 9783540404705

In order to compute stellar orbits in spiral galaxies the gravitational potential and its pattern speed must be known. Observationally, these parameters are difficult to determine, in particular for strongly barred galaxies. We will briefly review di

Interpretation of Observations of Spiral Structure in Terms of the Density Wave Theory

Autor: Per Olof Lindblad

Publikováno v: Symposium - International Astronomical Union. 58:399-412

A review is given of recent theoretical and observational work on the density wave theory of spiral structure. Emphasis is put on the kinematic picture, and the question whether modern observations reveal the existence of density waves is discussed.
