Investigating 3D Maps of Lyman Alpha Halos Around Radio-Loud Quasars at z > 3.6

The rapid growth of billion solar mass supermassive black holes (SMBHs) within 1 Gyr after the Big Bang requires extreme accretion scenarios. Theoretical models predict that these systems reside in highly biased regions, where the accretion is sustained by vast gas reservoirs from the circumgalactic medium (CGM), reaching kiloparsec scales. In particular, radio jets, present in around 10% of quasars, may also play a key role in SMBH galaxy growth; however, the role of radio jets in shaping the CGM remains unclear, with no systematic observations comparing radio-loud (RL) and radio-quiet (RQ) quasars.
