Galaxy Clustering around Nearby Luminous Quasars
We examine the clustering of galaxies around a sample of 20 luminous low redshift (z < ∼ 0.30) quasars observed with the Wide Field Camera-2 on the Hubble Space Telescope. The HST resolution makes possible galaxy identification brighter than V = 23.5 and as close as 2 to the quasar. We find a significant enhancement of galaxies within a projected separation of < ∼ 100 h kpc of the quasars. If w...
متن کاملLuminous Quasars in Luminous Early-Type Host Galaxies
Some recent observations of nearby quasars with HST have apparently failed to detect host galaxies. We review the HST observations as well as near infrared ground-based observations of the same objects. We nd that the quasar hosts can be detected in the HST data if they are smoothed suuciently to reveal low surface brightness. The smooth hosts are very diicult to detect with HST but are more ea...
متن کاملThe Clustering of Galaxies around Quasars
We study the cross-correlation between quasars and galaxies by embedding models for the formation and evolution of the two populations in cosmological N-body simulations. We adopt the quasar evolution model of Kauffmann & Haehnelt (2000), in which supermassive black holes are formed and fuelled during major mergers. We define the “bias” parameter bQG as the ratio of the cross-correlation functi...

متن کاملThe host galaxies of luminous radio - quiet quasars
We present the results of a deep K-band imaging study which reveals the host galaxies around a sample of 14 luminous radio-quiet quasars. The K-band images, obtained at UKIRT, are of sufficient quality to allow accurate modelling of the underlying host galaxy. Initially, the basic structure of the hosts is revealed using a modified Clean deconvolution routine optimised for this analysis. Two of...
