We measure the host galaxy properties of five quasars with
selected from SDSS and AEGIS, which fall within the JWST/HST CEERS survey area.
A PSF library is constructed based on stars in the full field-of-view of the
data and used with a 2-dimensional image modeling tool galight to decompose the
quasar and its host with multi-band filters available for HST ACS+WFC3 and JWST
NIRCAM (12 filters covering HST F606W to JWST F444W). As demonstrated, JWST
provides the first capability to detect quasar hosts at and enables
spatially-resolved studies of the underlying stellar populations at
within morphological structures (spiral arms, bar) not possible with HST.
Overall, we find quasar hosts to be disk-like, lack merger signatures, and have
sizes generally more compact than typical star-forming galaxies at their
respective stellar, thus in agreement with results at lower redshifts. The
fortuitous face-on orientation of SDSSJ1420+5300A at enables us to
find higher star formation and younger ages in the central kpc region
relative to the outskirts, which may help explain the relatively compact nature
of quasar hosts and pose a challenge to AGN feedback models.
