21-cm line observations of galaxies from Kazarian's lists

Abstract

Abstract. The 21-cm neutral hydrogen line has been measured for the first time in 39 non-Seyfert type galaxies from Kazarian list, with the Nançay radiotelescope. The line profiles, widths at 20% and 50% of the peak intensity, radial velocities as well as total fluxes are presented. The values of radial velocity are in fairly good agreement with those obtained from optical spectra. The width values at 20% of the peak vary in wide range from 113 km s −1 (KAZ 579) to 608 km s −1 for KAZ 566. Nine of our objects remained undetected, whether their HI-flux was too faint, the integration time too short, or the frequency sighted wrong. However, for part of them, there were positive hint of detection. Comments on individual objects are given.

Hydrogen content in Kazarian galaxies

“…In the previous paper (Tamazian et al 1997, hereafter Paper I) the hydrogen 21 cm line observational data obtained for the first time for 39 galaxies taken from Kazarian lists (Kazarian 1979; have been presented out of which 30 objects have shown the positive hint of detection. These observations were made with the Nançay radiotelescope in the course of several observing runs in 1996.…”
