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…
A kinematic study of the irregular dwarf galaxy NGC 2366 using HI and Halpha observations
J. van Eymeren, M. Marcelin, B. Koribalski +4
Abridged. Context. The metal content of dwarf galaxies and the metal enrichment of the intergalactic medium both suggest that mass loss from galaxies is a significant factor for th…
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…
First light of VLT/HiRISE: High-resolution spectroscopy of young giant exoplanets
A. Vigan, M. El Morsy, M. Lopez +46
A major endeavor of this decade is the direct characterization of young giant exoplanets at high spectral resolution to determine the composition of their atmosphere and infer thei…
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…
SUBARU prime focus spectrograph: integration, testing and performance for the first spectrograph
F. Madec, A. Le Fur, D. Le Mignant +22
The Prime Focus Spectrograph (PFS) of the Subaru Measurement of Images and Redshifts (SuMIRe) project for Subaru telescope consists in four identical spectrographs fed by 600 fiber…
Validation of strategies for coupling exoplanet PSFs into single-mode fibres for high-dispersion coronagraphy
M. El Morsy, A. Vigan, M. Lopez +13
On large ground-based telescopes, the combination of extreme adaptive optics (ExAO) and coronagraphy with high-dispersion spectroscopy (HDS), sometimes referred to as high-dispersi…
