Simulated host galaxy analogues of high-z quasars observed with JWST

Abstract

The hosts of two low-luminosity high-z quasars, J2255 + 0251 and J2236 + 0032, were recently detected using JWST 's NIRCam instrument. These represent the first high-z quasar host galaxy stellar detections and open a new window into studying high-z quasars. We examine the implications of the measured properties of J2255 + 0251 and J2236 + 0032 within the context of the hydrodynamic simulation BlueTides at z = 6.5. We find that these observed quasars fall on the BlueTides stellar to black hole mass relation and have similar luminosities to the brightest simulated quasars. We predict their star formation rates, estimating approximately 102-3 M⊙-yr-1 for both quasar hosts. J2255 + 0251 and J223..
