The magnification bias on submillimeter galaxies: cosmological constraints and large-scale bias corrections
The gravitational lensing effect of magnification bias can manifest itself through a non-negligible measurement of the cross-correlation function between a background and a foreground source sample with non-overlapping redshift distributions. Although cosmic shear measurements have played a predominant role in cosmological studies regarding the probing of mass distribution, we argue that choosing submillimeter galaxies as the background sample enhances the cross-correlation signal so as to provide an alternative and independent observable for this kind of analysis. In this talk, we will present our most recent results regarding cosmology and the large-scale biases which arise in the measurement process of the galaxy samples we used.
