Spectral observations of galaxies with UV excess

摘要

Spectral observations of 19 galaxies with UV-excesses from Kazarian's list are reported. The spectra were obtained with the 2.6-m telescope at the Byurakan Observatory using the SCORPIO spectral camera. A grism was used to obtain spectra in the wavelength interval lambda lambda 7420-3920 angstrom. 43 spectra in which emission lines are mainly observed were obtained from the 19 galaxies, except for the spectra of Kaz 21, Kaz 178, Kaz 183, and Kaz 184. The spectra of Kaz 17, Kaz 151, Kaz 153, and Kaz 357 have type Sy2 galactic features. In the spectra of the galaxies Kaz 17, Kaz 151, and Kaz 153, absorption lines are observed along with high excitation emission lines such as HeI lambda 5876 angstrom and HeII lambda 4686 angstrom. No lines were observed within the interval lambda lambda 7420-3920 angstrom in the spectra of the galaxies Kaz 183 and Kaz 184.
