Using the Tremaine-Weinberg method to measure pattern speeds from Hαvelocity maps
John Beckman, Kambiz Fathi, Nuria Piñol +3
The Tremaine-Weinberg method is a well-known model independent technique for measuring density wave pattern speeds in spiral galaxies. Here we show how it can be applied to the dat…
CCCP: A CCD Controller for Counting Photons
Olivier Daigle, Jean-Luc Gach, Christian Guillaume +3
CCCP, a CCD Controller for Counting Photons, is presented. This new controller uses a totally new clocking architecture and allows to drive the CCD in a novel way. Its design is op…
GHASP : An Halpha kinematic survey of spiral and irregular galaxies - VI. New Halpha data cubes for 108 galaxies
B. Epinat, P. Amram, M. Marcelin +7
We present the Fabry-Perot observations obtained for a new set of 108 galaxies that completes the GHASP survey (Gassendi HAlpha survey of SPirals). The GHASP survey consists of 3D…
GH FaS : Galaxy H-alpha Fabry-Perot System for the WHT
O. Hernandez, K. Fathi, C. Carignan +11
GHFaS a new Fabry-Perot system, is now available at the William Herschel Telescope. It was mounted, for the first time, at the Nasmyth focus of the 4.2 meter WHT on La Palma in…
GALEX observations of Low Surface Brightness Galaxies: UV color and star formation efficiency
S. Boissier, A. Gil de Paz, A. Boselli +7
We present GALEX UV observations of a sample of Low Surface Brightness (LSB) galaxies for which HI data are available, allowing us to estimate their star formation efficiency. We f…
Deep Fabry-Perot Halpha Observations of NGC 7793: a Very Extended Halpha Disk and a Truly Declining Rotation Curve
I. Dicaire, C. Carignan, P. Amram +5
Deep Halpha observations of the Sculptor Group galaxy NGC 7793 were obtained on the ESO 3.60m and the Marseille 36cm telescopes at La Silla, Chile. Halpha emission is detected all…
