Monster Radio Jet (>66 kpc) Observed in Quasar at z ∼ 5
We present the discovery of a large extended radio jet associated with the extremely radio-loud quasar J1601+3102 at z ∼ 5 from subarcsecond resolution imaging at 144 MHz with the International LOFAR Telescope.

Based on the magnetization, an accretion disk with a large-scale magnetic field can be separated into either standard and normal evolution or magnetically arrested disk (MAD), which are difficult to identify from observations. It is still unclear whether

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 deVaucoleurs profiles. By association, identifying and studying a sample of high-redshift,

Circumgalactic Environments Around Distant Quasars 3C 9 and 4C 05.84
We present results from the Quasar hosts Unveiled by high Angular Resolution Techniques survey studying the circumgalactic medium (CGM) by observing rest-frame UV emission lines Ly α , C iv , and He ii around two radio-loud quasars, 3C 9 ( z = 2.02) and ...
