Full calibration of the tomographic redshift distribution from the HSC PDR3 Shape Catalog with DESI
This episode discusses a paper that details the full calibration of four tomographic redshift bins from the HSC PDR3 Shape Catalog using Data Release 1 and 2 from DESI. The hosts discuss how this calibration relies on average raw angular density measurements, the use of DESI DR2 QSOs, and how cross-correlating different tracers builds a robust statistical picture for mapping redshift distributions.
