Journal ArticleDOI
HST imaging of the inner 3 arcseconds of NGC 1068 in the light of forbidden O III 5007 A
TL;DR: In this article, a high-resolution image of the barred spiral galaxy NGC 1068 was used to obtain a high spatial resolution forbidden O III 5007 A image, which showed more detail than any previously published images and resolved the NLR into several distinct clouds arranged in an apparently conical geometry.
Journal ArticleDOI
Steps toward determination of the size and structure of the broad-line region in active galactic nuclei. 5: Variability of the ultraviolet continuum and emission lines of NGC 3783

TL;DR: In this paper, the authors report on the results of intensive ultraviolet spectral monitoring of the Seyfert 1 galaxy NGC 3783, which was observed with the International Ultraviolet Explorer satellite on a regular basis for a total of 7 months, once every 4 days for the first 172 days and once every other day for the final 50 days.
Journal ArticleDOI
Maximum entropy deconvolution of the optical jet of 3C 273
TL;DR: The technique of maximum entropy image restoration is applied to the problem of deconvolving the point spread function from a deep, high-quality V band image of the optical jet of 3C 273 as discussed by the authors.

TL;DR: In this paper, the results of FOS spectroscopy of the continuum peak of NGC 1068 in the wavelength range 2200-7000 A are reported, revealing the emission lines to be complex in shape and to consist of a number of different velocity components.
