Cosmic Microwave Background (CMB) polarized light subjected to gravitational lensing effects, in addition to cosmic birefringence. On the far left, the white lines show the polarization pattern of the ...

It’s one of the most memorable moments of my career – and not in a good way. I was giving a talk to a room packed full of eminent astrophysicists, but there had been a bit of a childcare crisis, so ...

Thanks to gravitational lensing, scientists have measured the total mass of many galaxy clusters, which revealed that all the matter they can see isn’t enough to create the warping effects they ...

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 ...
