The nuclear to host galaxy relation of high redshift quasars

چکیده
We present near-infrared imaging obtained with ESO VLT+ISAAC of the host galaxies of a sample of low luminosity quasars in the redshift range 1 < z < 2, aimed at investigating the relationship between the nuclear and host galaxy luminosities at high redshift. This work complements our previous systematic study to trace the cosmological evolution of the host galaxies of high luminosity quasars (Falomo et al. 2004). The new sample includes 15 low luminosity quasars, of which nine are radio–loud (RLQ) and six are radio–quiet (RQQ). They have similar distribution of redshift and optical luminosity, and together with the high luminosity quasars they cover a large range (∼4 mag) of the quasar

Near-infrared imaging of the host galaxies of flat spectrum radio quasars
We present the results of a high resolution (0.27′′ px−1) near-infrared H band (1.65 μm) imaging survey of a complete sample of 20 flat spectrum radio quasars (FSRQ) extracted from the 2Jy catalogue of radio sources (Wall & Peacock 1985). The observed objects are intrinsically luminous with median M(B) = -25.5. The median redshift of the objects in the sample is z = 0.65. At this redshift, the ...
متن کاملThe luminous host galaxies of high redshift BL Lac objects
We present the first near-infrared K s-band (2.1 µm) imaging study of a sizeable sample of 13 high redshift (0.6 < z < 1.3) BL Lac objects in order to characterize the properties of their host galaxies. We are able to clearly detect the surrounding nebulosity in eight objects, and marginally in three others. In all the well resolved objects, we find that the host galaxy is well represented by a...
متن کاملCalibrating the Galaxy Halo – Black Hole Relation Based on the Clustering of Quasars
The observed number counts of quasars may be explained either by long-lived activity within rare massive hosts, or by short-lived activity within smaller, more common hosts. It has been argued that quasar lifetimes may therefore be inferred from their clustering length, which determines the typical mass of the quasar host. Here we point out that the relationship between the mass of the black-ho...
متن کاملThe Co Tully-fisher Relation and Implications for the Host Galaxies of High-redshift Quasars
The integrated line width derived from CO spectroscopy provides a powerful tool to study the internal kinematics of extragalactic objects, including quasars at high redshift, provided that the observed line width can be properly translated to more conventionally used kinematical parameters of galaxies. We show, through construction of a Ks-band CO Tully-Fisher relation for nearby galaxies spann...
متن کاملNear-infrared Adaptive Optics Imaging of High-redshift Quasars
The properties of high-redshift quasar host galaxies are studied in order to investigate the connection between galaxy evolution, nuclear activity, and the formation of supermassive black holes. We combine new near-IR observations of three high-redshift quasars (2 < z < 3), obtained at the ESOVery Large Telescope equipped with adaptive optics, with selected data from the literature. For the thr...
