Abstract:
We present an integral field spectroscopic study with the Gemini
Multi-Object Spectrograph (GMOS) of the unusual blue compact dwarf
(BCD) galaxy Mrk 996.
We show through velocity and dispersion maps, emission-line intensity
and ratio maps, and by a new technique of electron density limit
imaging that the ionization properties of different regions in Mrk 996
are correlated with their kinematic properties.
Description:
The observations were obtained with the Gemini Multi-Object
Spectrograph (GMOS) and the Integral Field Unit (IFU) (Allington-Smith
et al. 2002, hereafter GMOS/IFU) at the Gemini South Telescope in
Chile. They were made during the nights of October 20, 2008, using
the grating B1200+ G5321 (B1200) covering the wavelength region from
3667Å to 5142Å with a spectral resolution of 0.24Å, and of
November 6, 2008, using the grating R831+ G5322 (R831) with a spectral
resolution of 0.34Å, covering the wavelength region from 5095Å
to 7223Å, with an overlap of ∼50Å between the red and blue
spectral ranges, in the one-slit mode.
