Beyond the sphericity assumption in dynamical HI models
Pieter Buyle, Herwig Dejonghe, Gianfranco Gentile
It is generally agreed that the rotational velocities of spiral galaxies indicate that a lot of matter is unseen. Hitherto, the majority of these mass models are all based on spher…
Dynamical streams in the solar neighbourhood
B. Famaey, A. Jorissen, X. Luri +4
The true nature of the Hyades and Sirius superclusters is still an open question. In this contribution, we confront Eggen's hypothesis that they are cluster remnants with the resul…
The PNLF distance to the Sculptor Group galaxy NGC 55
G. C. Van de Steene, G. H. Jacoby, C. Praet +2
We identified 21 new Planetary Nebula (PN) candidates in the Sculptor Group galaxy NGC 55. We determined a most likely distance of 2.00 +/- 0.2 Mpc using the Planetary Nebulae Lumi…
The dynamics of the dE galaxy FS76 : bridging the kinematic dichotomy between Es and dEs
S. De Rijcke, H. Dejonghe, W. W. Zeilinger +1
We present major and minor axis kinematics out to 2 half-light radii for the bright (M_B=-16.7) dwarf elliptical FS76, a member of the NGC5044 group. Its velocity dispersion is 46…
Dynamical models for dusty disk galaxies
Maarten Baes, Herwig Dejonghe
Disk galaxies contain a large amount of interstellar dust, which affects the projection of kinematic quantities. We investigate in detail the effects of dust extinction on the mean…
Numerical calculation of linear modes in stellar disks
P. Vauterin, H. Dejonghe
We present a method for solving the two-dimensional linearized collisionless Boltzmann equation using Fourier expansion along the orbits. It resembles very much solutions present i…
