Euclid: calibrating photometric redshifts with spectroscopic cross-correlations

HIGHLIGHTS

  • who: Naidoo K. and collaborators from the (UNIVERSITY) have published the article: Euclid: Calibrating photometric redshifts with spectroscopic cross-correlations, in the Journal: (JOURNAL)
  • what: The authors determine whether the mean redshift hzi of ten Euclid tomographic redshift bins can be calibrated with an algorithm that performs well on current galaxy survey data. The authors show that hzi is measured in each tomographic redshift bin to an accuracy of order 0.01 or better. The authors assess the potential for photometric-spectroscopic crosscorrelations to form a major component of the redshift calibration in Euclid. The . . .
