Accurate determination of the mass distribution in spiral galaxies III. Fabry-Perot imaging spectroscopy of 6 spiral galaxies
S. Blais-Ouellette, P. Amram, C. Carignan +1
High resolution Fabry-Perot data of six spiral galaxies are presented. Those data extend the previous sample of spiral galaxies studied with high resolution 3D spectroscopy to earl…
A Virgo high-resolution Halpha kinematical survey
L. Chemin, C. Balkowski, V. Cayatte +9
We have completed a survey of 30 Virgo cluster galaxies in the Halpha emission-line using Fabry-Perot interferometry. The goal of the survey is to obtain a high angular resolution…
Probing Halos of Galaxies at Very Large Radii using Background QSOs
Stephanie Cote, Rosemary Wyse, Claude Carignan +2
(ABRIDGED) Gaseous halos of nine nearby galaxies (with redshifts cz < 6000 km/s) were probed at large galactocentric radii using background quasars observed with HST GHRS and STIS.…
The Compact Group of Galaxies HCG 31 is in an early phase of merging
P. Amram, C. Mendes de Oliveira, H. Plana +1
We have obtained high spectral resolution (R = 45900) Fabry-Perot velocity maps of the Hickson Compact Group HCG 31 in order to revisit the important problem of the merger nature o…
L3CCD results in pure photon counting mode
Olivier Daigle, Jean-Luc Gach, Christian Guillaume +3
Theoretically, L3CCDs are perfect photon counting devices promising high quantum efficiency (90%) and sub-electron readout noise (<0.1 e-). We discuss how a back-thinned 5…
Bar Parameters From Halpha Observations: Tremaine-Weinberg method with Halpha velocity fields
O. Hernandez, C. Carignan, P. Amram +1
The very first results of the application of the Tremaine-Weinberg (hereafter TW) method on Halpha velocity fields are presented to find pattern speeds of galaxies. The technique i…
