Since the third Gaia data release in 2022, wide binary stars with separation greater than several thousand astronomical units have been intensely investigated across the world, to probe the nature of ...
Wide binary stars as direct probes of the nature of gravity at low acceleration weaker than about 1 nanometer per second squared have been hotly debated. The nature of gravity at such low acceleration ...
Laser plasma acceleration exploits the extreme electric fields generated in plasmas to produce high-energy electron beams over centimetre‐scale distances, in stark contrast to the kilometre‐scale ...
