The kinematics of the diffuse ionized gas in NGC 4666
Pierre Voigtländer, Peter Kamphuis, Michel Marcelin +2
The global properties of the interstellar medium with processes such as infall and outflow of gas and a large scale circulation of matter and its consequences for star formation an…
Deep Fabry-Perot Halpha observations of two Sculptor group galaxies, NGC 247 and NGC 300
J. Hlavacek-Larrondo, M. Marcelin, B. Epinat +4
It has been suggested that diffuse ionized gas can extend all the way to the end of the HI disc, and even beyond, such as in the case of the warped galaxy NGC 253 (Bland-Hawthorn e…
Deep Hα Observations of NGC 253: a Very Extended and Possibly Declining Rotation Curve?
J. Hlavacek-Larrondo, C. Carignan, O. Daigle +4
This study presents a deep Hα kinematical analysis of the Sculptor Group galaxy NGC253. The Fabry-Perot data were taken with the 36-cm Marseille Telescope in La Silla, Chile, using…
A kinematic study of the irregular dwarf galaxy NGC 4861 using HI and Halpha observations
J. van Eymeren, M. Marcelin, B. S. Koribalski +4
Context. Outflows powered by the injection of kinetic energy from massive stars can strongly affect the chemical evolution of galaxies, in particular of dwarf galaxies, as their lo…
Evidence for strong dynamical evolution in disk galaxies through the last 11 Gyr. GHASP VIII: A local reference sample of rotating disk galaxies for high redshift studies
B. Epinat, P. Amram, C. Balkowski +1
[Abridged] Due to their large distances, high-z galaxies are observed at a very low spatial resolution. In order to disentangle the evolution of galaxy kinematics from low resoluti…
