Near-infrared adaptive optics imaging of high redshift quasars
R. Falomo, A. Treves, J. K. Kotilainen +2
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 supermassi…
The nuclear to host galaxy relation of high redshift quasars
J. K. Kotilainen, R. Falomo, M. Labita +2
We present near-infrared imaging with ESO VLT+ISAAC of the host galaxies of low luminosity quasars in the redshift range 1 < z < 2, aimed at investigating the relationship between…
The host galaxies of radio-quiet quasars at 0.5<z<1.0
T. Hyvonen, J. K. Kotilainen, E. Orndahl +2
We present near-infrared H-band imaging of 15 intermediate redshift (0.5<z<1) radio quiet quasars (RQQ) in order to characterize the properties of their host galaxies. We are able…
The host galaxies of low luminosity quasars at high redshift
J. K. Kotilainen, R. Falomo, A. Treves +1
We present VLT/ISAAC near-infrared imaging of the host galaxies of 15 low luminosity quasars at 1 < z < 2. This work complements our studies to trace the cosmological evolution of…
The evolution of Radio Loud Quasar host galaxies: AO observations at z = 3
R. Falomo, J. K. Kotilainen, R. Scarpa +2
We report on ESO--VLT adaptive optics imaging of one radio-loud quasar at z 3. In spite of the large distance of the object we are able to detect its surrounding extended ne…
