Study of the HII regions in the spiral galaxy NGC6384
A. A. Hakobyan, A. R. Petrosian, A. A. Yeghiazaryan +1
The galaxy NGC6384 has been observed with an IPCS through H alpha and [NII] narrow-band interference filters for direct imagery with the 2.6 m Byurakan telescope. We studied main p…
Spiral inflow feeding the nuclear starburst in M83, observed in H-alpha emission with the GHAFAS Fabry-Perot interferometer
Kambiz Fathi, John E. Beckman, Andreas A. Lundgren +8
We present observations of the nearby barred starburst galaxy, M83 (NGC5236), with the new Fabry-Perot interferometer GHAFAS mounted on the 4.2 meter William Herschel Telescope on…
A Virgo high-resolution Halpha kinematical survey : II. The Atlas
L. Chemin, C. Balkowski, V. Cayatte +8
A catalog of ionized gas velocity fields for a sample of 30 spiral and irregular galaxies of the Virgo cluster has been obtained by using three-dimensional optical data. The aim of…
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…
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…
A 3D Optical Spectroscopy Study of Low Surface Brightness Galaxies
L. Chemin, P. Amram, C. Carignan +6
We present Halpha emission line velocity fields of two Low Surface Brightness galaxies - UGC 628 and UGC 5005 - obtained using Fabry-Perot interferometry observations at the Canada…
