Description

An analysis of spectra obtained with an approximately 95 A/mm-dispersion spectrograph has yielded new data on the structure of the central region of the Seyfert galaxy Markaryan 298 IC 1182-4. The central region's gaseous formation has a diameter of 6.5 kpc, an electron density of 0.2-0.5/cu cm, and a mass ratio (M/solar-M) ranging from 0.6 x 10 to the 7th to 7 x 10 to the 8th. The data further suggests that this gas formation is associated with condensations of blue stars, and interacts with both the nucleus and the eastern elongated structure of the galaxy. The nucleus of Markaryan 298 is found to be a type 1 Seyfert which is distorted by dust absorption, with a hydrogen envelope that is opaque in the Balmer lines and inhomogeneous in its physical conditions. Gas condensations in the forbidden line emission region are found to be of the densities 20, 10,000 and 200,000/cu cm
