Ion-supported tori and the origin of radio jets
TL;DR: In this paper, it is proposed that at the centre of each radio galaxy is a spinning black hole surrounded by a torus of gas too hot and tenuous to radiate efficiently.

Hubble Space Telescope Images of a Sample of 20 Nearby Luminous Quasars
TL;DR: In this paper, a representative sample of 20 intrinsically luminous quasars with redshifts smaller than 0.30 were observed with the Wide-Field Camera of the Hubble Space Telescope (HST).

TL;DR: In this paper, the role of scatter in the black hole-spheroid mass relation in determining the ratio of quasar to host-galaxy luminosity, by generating simulated populations of quasars lying in hosts with a Schechter mass function was investigated.

TL;DR: In this article, the authors reported observations of four quasars, made with the refurbished Hubble Space Telescope, with very close companions, and found that the quasar reside in luminous elliptical elliptical galaxies with close companions.
