Spectroscopic source redshifts and parameter constraints from weak lensing and CMB
Mustapha Ishak, Christopher M. Hirata
Weak lensing is a potentially robust and model-independent cosmological probe, but its accuracy is dependent on knowledge of the redshift distribution of the source galaxies used.…
