The unusual barred S0 galaxy NGC 4546.
Abstract
The results of spectroscopic and photometric observations of NGC 4546 in May 1986 are reported. Details of the observational techniques and instrumentation employed for the scans in the 4900-5700 A interval are described. The spectral lines of the gas in the bar indicated that the gas rotates in a direction opposite to the stars in NGC 4546, which may be a visual artifact of the gas not being coplanar with the stars. Several hypotheses are presented for the source of the gas.
