Context. The ESA Euclid mission will produce photometric galaxy samples over 15 000
square degrees of the sky that will be rich for clustering and weak lensing statistics. The
accuracy of the cosmological constraints derived from these measurements will depend on
the knowledge of the underlying redshift distributions based on photometric redshift
calibrations. Aims. A new approach is proposed to use the stacked spectra from Euclid
slitless spectroscopy to augment broad-band photometric information to constrain the�…
