Spectropolarimetric observations of the quasar 3C 273 over the range 3200-8000 A show wavelength-dependent polarization in the continuum, while the lines had no detectable polarization. The total polarization at the red end spectrum was near 2.5 percent, the highest ever measured for 3C 273. No wavelength dependence of the polarized flux is

We are living a renaissance of radio survey work: the size of source catalogues published in the first two years of this decade exceeds that of the entire 1980s! The total number of published flux densities in mid-1992 is probably nearing ~700,000 and is estimated to grow by a factor of four by the end of the decade. The number of known optical

Sixty-one bidimensionally distributed spectra covering the circumnuclear region of NGC 4161 within a radius of about 6.5 arcsec are presented. The local conditions and the mean velocity field are studied from an analysis of the H-alpha, forbidden N II 6548, 6584, and forbidden S II 6716, 6731 lines. The alignment of the line intensity maps in the

We present what we believe to be the first truly simultaneous UBVRI photopolarimetric results for a sample of eight 'normal' quasars. In five of these quasars we have not detected any measurable polarization, this result being consistent in some cases, but not necessarily in others, with the previous white light measurements of these quasars. 3C
