Researchers find gravitational lensing has significant effect on cosmic birefringence

Tokyo, Japan (SPX) Nov 03, 2023

Future missions will be able to find signatures of violating the parity-symmetry in the cosmic microwave background polarization more accurately after a pair of researchers has managed to take into account the gravitational lensing effect, reports a new study in Physical Review D, selected as an Editors' Suggestion. How far does the universe extend? When and how did the universe begin? Cos
