3D spectroscopy with VLT/GIRAFFE. III. Mapping electron densities in distant galaxies.

Abstract (from CDS):

We used the moderately high spectral resolution of FLAMES/GIRAFFE (R=10000) to derive electron densities from [OII] line ratios in 6 galaxies at z∼0.55. These measurements have been done through the GIRAFFE multiple integral field units and are the very first mapping of electron densities in such distant objects. This allows us to confirm an outflow and identify the role of giant HII regions in galactic disks. Such measurements could be used in the future to investigate the nature of the physical processes responsible for the high star formations rates observed in galaxies between z∼0.4 and z∼1.
