The Performance of MEFOS, the ESO Multi-Object Fibre Spectrograph
P. Felenbok, J. Guérin, A. Fernandez +3
We are describing a new multi-fibre positioner, MEFOS, that was in general use at the La Silla Observatory, and implemented at the prime focus of the ESO 3.6 m telescope. It is an…
CFRS XIV: Spectral Properties Of Field Galaxies Up To z = 1
F. Hammer, H. Flores, S. J. Lilly +6
The spectral properties of more than 400 CFRS galaxies and their changes over the redshift interval 0 - 1.3 are investigated. Emission line intensities and equivalent widths for ac…
UV HST Spectroscopy of Star-Forming Galaxies
D. Kunth, J. Lequeux, J. M. Mas-Hesse +2
HST spectroscopical observations of 8 HII galaxies are reported. Ly alpha emission was detected in 4 of them. We find that the velocity structure of the gas is the main determining…
Tidal thickening of galaxy disks
Vladimir Reshetnikov, Francoise Combes
We have studied a sample of 24 edge-on interacting galaxies and compared them to edge-on isolated galaxies, to investigate the effects of tidal interaction on disk thickening. We f…
On gravitational waves emitted by an ensemble of rotating neutron stars
A. Giazotto, S. Bonazzola, E. Gourgoulhon
We study the possibility to detect the gravitational wave background generated by all the neutron stars in the Galaxy with only one gravitational wave interferometric detector. The…
Angular momentum transport by internal waves in the solar interior
Jean-Paul Zahn, Suzanne Talon, Jose Matias
The internal gravity waves of low frequency which are emitted at the base of the solar convection zone are able to extract angular momentum from the radiative interior. We evaluate…
