On the absence of broad MgII emission-line variability in NGC 3516 during 1996
(University of Chicago Press: Astrophysical Journal Letters, 1999-02-20)
During the 1996 HST/FOS monitoring campaign of the Seyfert 1 galaxy NGC 3516, the UV continuum showed a factor of 5 variation; correspondingly the strongest broad UV emission lines (e.g. Ly, Civ) displayed somewhat weaker, ...
PKS2250-41 and the role of jet-cloud interactions in powerful radio galaxies (full paper)
(Blackwell Publishing: Monthly Notices of the Royal Astronomical Society, 1999-02)
We present high resolution, long-slit spectra of the jet-cloud interaction in the powerful southern radio galaxy PKS2250-41.We have resolved the emission lines into two main kinematic components: a broad component (FWHM ...
