Modelling galactic spectra: I - A dynamical model for NGC3258
V. De Bruyne, S. De Rijcke, H. Dejonghe +1
In this paper we present a method to analyse absorption line spectra of a galaxy designed to determine the stellar dynamics and the stellar populations by a direct fit to the spect…
Modelling galactic spectra: II - Simultaneous study of stellar dynamics and stellar mix in NGC3258
V. De Bruyne, S. De Rijcke, H. Dejonghe +1
In this paper we adopt a method to analyse absorption line spectra from elliptical galaxies that determines the dynamics of the galaxy and at the same time offers a way to study th…
Realistic error estimates on kinematic parameters
V. De Bruyne, P. Vauterin, S. De Rijcke +1
Current error estimates on kinematic parameters are based on the assumption that the data points in the spectra follow a Poisson distribution. For realistic data that have undergon…
The internal dynamics of very flattened normal galaxies: Stellar distribution functions for NGC 4697
H. Dejonghe, V. De Bruyne, P. Vauterin +1
Using the photometry and the kinematic data, part of which acquired with the NTT, we constructed a 2-integral and a 3-integral distribution function for NGC 4697. We detected a nuc…
