15 years ago I had to scrape #HST #NICMOS parallel observations for random coverage of 1<z<2 #quasar #hostgalaxies in the near-infrared, to find 10 that I could analyse in terms of structure and stellar mass.
With #ESAEuclid we will cover 15.000 deg^2 and probably cover 10.000 of such quasars. Or 100.000? At lower angular resolution, but much better defined PSF.

So, have you taken notice that we have now seen the stellar #hostgalaxies of #quasars at z=6.4? Using #JWST we looked at the first two SHELLQ quasars which are ~x10 fainter than the most luminous quasars at high-z. And their host galaxies can clearly be seen. Off-center and massive (logM*~10^8.5). This was not attainable with HST or from the ground.
