چکیده
There are only five radio-loud quasars currently known within 1 Gyr from the Big Bang ( z > 6) and properties of their host galaxies have not been explored in detail. We present a NOrthern Extended Millimeter Array (NOEMA) survey [CII] (158 ?m) underlying continuum emission four 6 quasars, revealing diverse properties. J0309+2717 = 6.10) has bright line continuum, implying that galaxy is starburst with star-formation rate SFR 340–1200 M ? yr ?1 . J1429+5447 6.18) 520 ? 870 its profile consistent two Gaussians, which could be interpreted as merger.

Although NOEMA data tentatively reveal component wide ?1400 km s , sensitivity our current sufficient to confirm it.

If radio jets do significantly contribute IR luminosities, suggests there no feedback jet on star formation

High-Redshift, Radio-Loud Quasars
I discuss two programs to study radio-loud quasars at high (z ∼ > 4) redshift. Quasars are the most luminous, non-transient objects known and are observed to the earliest cosmic epochs. At lower redshifts, radio-loud quasars are associated with host galaxies having de Vaucoleurs profiles. By association, identifying and studying a sample of high-redshift, radio-loud quasars provides important c...
متن کاملThe cluster environments of radio loud quasars
We have carried out multi-colour imaging of the fields of a statistically complete sample of low-frequency selected radio loud quasars at 0.6 < z < 1.1, in order to determine the characteristics of their environments. The largest radio sources are located in the field, and smaller steep-spectrum sources are more likely to be found in richer environments, from compact groups through to clusters....
متن کاملRadio Variability of Radio Quiet and Radio Loud Quasars
The majority of quasars are weak in their radio emission, with flux densities comparable to those in the optical, and energies far lower. A small fraction, about 10%, are hundreds to thousands of times stronger in the radio. Conventional wisdom holds that there are two classes of quasars, the radio quiets and radio louds, with a deficit of sources having intermediate power. Are there really two
متن کاملThe Environments of Radio-loud Quasars
We have obtained multi-colour imaging of a representative, statistically complete sample of low-frequency selected (S408MHz > 0.95Jy) radio loud quasars at intermediate (0.6 < z < 1.1) redshifts. These sources are found in a variety of environments, from the field through to rich clusters. We show that statistical measures of environmental richness, based upon single-band observations are inade...
متن کاملThe Host Galaxies of Radio-loud and Radio-quiet Quasars
I review our knowledge of the properties of the host galaxies of radioloud and radio-quiet quasars, both in comparison to each other and in the context of the general galaxy population. It is now clear that the hosts of radio-loud and radio-quiet quasars with MV < −23.5 are virtually all massive elliptical galaxies. The masses of these spheroids are as expected given the relationship between bl...
