Panoramic Spectroscopy of Galaxies with Star-Formation Regions. Study of SBS0750+603A

  • S. A. HakopianEmail author

Results of 3D-spectroscopy of the galaxy SBS0750+603A based on observations at the 6-m telescope of the Special Astrophysical Observatory (SAO) of the Russian Academy of Sciences with the MPFS panoramic spectrograph are reported. This work was part of detailed studies of galaxies with active star formation included in one of the seven selected samples formed on the base of the Second Byurakan Spectral Sky Survey. Under investigation is a set of comprehensively coupled problems associated with star-formation processes in the evolutionary chain of galaxies. The distributions of the parameters of the Hα hydrogen recombination line and the forbidden nitrogen [NII] 6548, 6583 and sulfur [SII] 6716, 6731 lines over the galactic field of SBS0750+603A are analyzed. Three main components of the galaxy with four HII regions lying along an axis with position angle PA~140° are identified. The radial velocity field reaffirms an irregular structure and indicates rotation around this axis to be the main characteristic of the kinematics of the gaseous masses. The parameters characterizing the HII regions include the equivalent radius Req, the luminosity in the line L (Hα), the star formation rate SFR (Hα), which ranges from 0.7-0.11 M /year, and others.
