Spectroscopic Studies of Starburst Galaxies; the Dynamical Structure of Blue Compact Dwarf Galaxy Haro 6
We carried out photometric and spectroscopic observations of the blue compact dwarf galaxy Haro 6 in the Virgo Cluster of Galaxies. The long-slit spectroscopy was employed at three position angles, ϕ = 0°, ϕ = 30°, and ϕ = 120° CCD camera mounted on the Cassegrain Spectrograph. Based on the mean int...
