摘要: The existence of primordial magnetic fields can induce matter perturbations with additional power at small scales as compared to the usual $\Lambda$CDM model. We study its implication within context two-point shear correlation function from gravitational lensing. show that field leave imprints on angular $\lesssim \hbox{a few arcmin}$. results are CFHTLS data, which yields some strongest known constraints parameters (strength and spectral index) field. also discuss possibility detecting sub-nano Gauss using future missions such SNAP.
