A quasar-galaxy merger at z ∼ 6.2: rapid host growth via the accretion of two massive satellite galaxies

Show other versions (1)

We present JWST/NIRSpec integral field spectroscopy in the rest-frame optical bands of the system PJ308–21, a quasar at z = 6.2342 caught as its host galaxy interacts with companion galaxies. We detect the spatially extended emission of several emission lines (Hα, Hβ, [OIII], [NII], [SII], and HeII)...
