A Tunable-Filter study of Blue Compact Dwarf Galaxies
PI:Hector Castañeda
ABSTRACT
We propose to study a sample of Blue Compact Dwarf (BCD) galaxies using the Tunable Filters of OSIRIS at the 10.4m GTC. The optical data will produce images in the wavelengths of Hα, Hβ, [NeIII]λ3869, [OII]λ3727, [OIII]λ4363 and λ5007, [NII]λ5755 and λ6584, Heλ6678, [SII]λ6717 and λ6731, [SIII] 9069, as well as the WR emission features at λλ4850-4686 and λλ5698-5808. The high-quality data will provide us with an unprecedent set of images for this kind of objects that will allow to determine the amount, extension and shape of ionized gas at high and low surface brigthnesses, the extinction maps, the global and local star formation rate, the electron density and temperature spatial distribution, the spatial variations in the chemical composition and the precise localization of the WR stars.
