Monster radio jet (>66 kpc) observed in quasar at z5
Anniek J. Gloudemans, Frits Sweijen, Leah K. Morabito +6
We present the discovery of a large extended radio jet associated with the extremely radio-loud quasar J1601+3102 at from sub-arcsecond resolution imaging at 144 MHz with…
Fast Outflow in the Host Galaxy of the Luminous z 7.5 Quasar J10072115
Weizhe Liu, Xiaohui Fan, Jinyi Yang +24
James Webb Space Telescope opens a new window to directly probe luminous quasars powered by billion solar mass black holes in the epoch of reionization and their co-evolution with…
No Redshift Evolution in the Fe II/Mg II Flux Ratios of Quasars across Cosmic Time
Danyang Jiang, Masafusa Onoue, Linhua Jiang +13
The Fe II/Mg II emission line flux ratio in quasar spectra serves as a proxy for the relative Fe to alpha-element abundances in the broad line regions of quasars. Due to the expect…
A SPectroscopic survey of biased halos In the Reionization Era (ASPIRE): Broad-line AGN at revealed by JWST/NIRCam WFSS
Xiaojing Lin, Feige Wang, Xiaohui Fan +33
Low-luminosity AGNs with low-mass black holes (BHs) in the early universe are fundamental to understanding the BH growth and their co-evolution with the host galaxies. Utilizing JW…
A blazar in the epoch of reionization
Eduardo Banados, Emmanuel Momjian, Thomas Connor +21
Relativistic jets are thought to play a crucial role in the formation and evolution of massive galaxies and supermassive black holes. Blazars, which are quasars with jets aligned a…
Optical and near-infrared spectroscopy of quasars at : public data release and composite spectrum
Silvia Onorato, Joseph F. Hennawi, Jan-Torge Schindler +18
We present optical and near-infrared (NIR) spectroscopic observations for a sample of quasars at with absolute magnitudes at Å in the range $-28.82…
