Diffusion of radial action in a galactic disc
Herve Wozniak
Context. Stellar migration of the galactic disc stars has been invoked to explain the dispersion of stellar metallicity observed in the solar neighborhood. Aims. We seek to identif…
Stellar migration in galaxy discs using the Chirikov diffusion rate
Hervé Wozniak
We are re-examining the problem of stellar migration in disc galaxies from a diffusion perspective. We use for the first time the formulation of the diffusion rates introduced by \…
A Virgo Environmental Survey Tracing Ionised Gas Emission (VESTIGE).I. Introduction to the Survey
A. Boselli, M. Fossati, L. Ferrarese +56
The Virgo Environmental Survey Tracing Ionised Gas Emission (VESTIGE) is a blind narrow-band Halpha+[NII] imaging survey carried out with MegaCam at the Canada-France-Hawaii Telesc…
How can double-barred galaxies be long-lived?
Herve Wozniak
Double-barred galaxies account for almost one third of all barred galaxies, suggesting that secondary stellar bars, which are embedded in large-scale primary bars, are long-lived s…
Explaining two circumnuclear star forming rings in NGC5248
T. P. R. van der Laan, E. Schinnerer, E. Emsellem +7
The distribution of gas in the central kiloparsec of a galaxy has a dynamically rapid evolution. Nonaxisymmetries in the gravitational potential of the galactic disk, such as a lar…
An Overview of the Dwarf Galaxy Survey
S. C. Madden, A. Remy Ruyer, M. Galametz +38
The Dwarf Galaxy Survey (DGS) program is studying low-metallicity galaxies using 230h of far-infrared (FIR) and submillimetre (submm) photometric and spectroscopic observations of…
