The first observation of a cosmic effect could give astronomers a new tool for understanding the forces behind the Universe's formation and growth, including the enigmatic phenomena of dark energy and dark matter.
An international team led by Princeton University, and including Oxford University scientists, has detected the movement of distant galaxy clusters via the kinematic Sunyaev-Zel'dovich (kSZ) effect, which has never before been seen.
To find the kSZ effect, the researchers combined data from the ACT and BOSS projects.
