Structural parameters of nearby emission-line galaxies

摘要: We present the results of an investigation on main structural properties derived from VRI and Ha surface photometry galaxies hosting nuclear emission-line regions [including Seyfert 1, 2, low-ionization emission region (LINER) starburst galaxies] as compared with normal galaxies. Our original sample comprises 22 active galaxies, four starbursts one galaxy has been extended several samples obtained literature. Bulge disc parameters, along bulge-to-disc luminosity ratio, have applying iterative procedure. The resulting parameters combined additional data in order to reach a statistically significant sample. find some differences bulge distribution across different types that could imply families bulges physical properties. characteristic colours defined for our control early-type objects. suggest stellar populations are comparable
