Abstract
The class of dust-lane ellipticals is characterized by the presence of a lane of absorbing matter which crosses an elliptical-like galaxy body. The dust lane consists of gas and dust and appears ring-like or as a narrow disk seen edge-on. Bertola & Galletta (1978) pointed out the case of minor-axis dust-lane ellipticals, NGC 5128 (Cen A) being a prototype. Successively in a survey carried out by Hawarden et al. (1981) also galaxies having dust lanes along their major axis or along intermediate axes have been identified. A list of “bona fide” dust-lane ellipticals has been presented by Bertola (1987). Thirty objects are found to have minor-axis dust lanes, while on the contrary only nine major-axis dust-lane ellipticals were identified. In addition seven galaxies having a dust lane along an intermediate axis were listed.
