Disks in elliptical galaxies

摘要: The abundance and strength of disk components in elliptical galaxies are investigated by studying the photometric properties models containing a spheroidal r exp 1/4-law bulge weak exponential disk. Pointed isophotes observed substantial fraction galaxies. If these isophote distortions interpreted framework present models, then statistics samples suggest that almost all radio-weak ellipticals could have disks roughly 20 percent light. It is shown E5 galaxy NGC 4660 has signatures third 30 refs.
