NGC 1428: from the discordant redshift caused by a star, to the determination of the morphological type.
Abstract
We summarise the main results of our study of NGC 1428, an early-type galaxy belonging to the Fornax cluster. By means of long-slit spectroscopic data we study it's kinematics and also solve the problems connected to a star superimposed on its nucleus - which have led to wrong measurements of its redshift in the past. The present analysis allows us to determine the morphological type of NGC 1428 as well as an accurate value of its redshift.
