Determination of the relative spectrophotometric gradients of galaxies. IV
Relative spectrophotometric gradients of continua are determined for 195galaxies. The spectra have been obtained with the 70-cm meniscustelescope of the Abastumani Astrophysical Observatory using a 2-degpreobjective prism (the reverse linear dispersion was 1200 A/mm inH-gamma). The gradient values were reduced to the AO spectral class andcorrected for light absorption in the Galaxy.
| Luminosity and mass models for the barred spiral galaxies NGC 7741, NGC 3359 and NGC 7479
From two-dimensional photometric data and the radial velocity field ofthe ionized gas, luminosity distributions and mass models of threelate-type barred spiral galaxies, NGC 7741, NGC 3359, and NGC 7479, areobtained. It is shown that the isoradial velocities clearly exhibit theclassical S-shaped distortion, expected from the gravitational pull ofthe bar. The near equality of the mass/luminosity ratios of the stellarbar and its surrounding disk is seen for the first two galaxies, but asignificantly lower value is seen for NGC 7479.
