The power of relativistic jets is larger than the luminosity of their accretion disks
G. Ghisellini, F. Tavecchio, L. Maraschi +2
Theoretical models for the production of relativistic jets from active galactic nuclei predict that jet power arises from the spin and mass of the central black hole, as well as th…
Blazar candidates beyond redshift 4 observed by Swift
T. Sbarrato, G. Ghisellini, G. Tagliaferri +4
We have selected SDSS J222032.50+002537.5 and SDSS J142048.01+120545.9 as best blazar candidates out of a complete sample of extremely radio-loud quasars at z>4, with highly massiv…
The jet-disc connection in AGN
T. Sbarrato, P. Padovani, G. Ghisellini
We present our latest results on the connection between accretion rate and relativistic jet power in AGN, by using a large sample which includes mostly blazars, but contains also s…
SDSS J114657.79+403708.6: the third most distant blazar at z=5.0
G. Ghisellini, T. Sbarrato, G. Tagliaferri +5
The radio-loud quasar SDSS J114657.79+403708.6 at a redshift z=5.0 is one of the most distant radio-loud objects. The IR-optical luminosity and spectrum suggest that its black hole…
