Using the Neutron Star Interior Composition Explorer (NICER) onboard the International Space Station (ISS), an international team of astronomers has detected millihertz quasi-periodic oscillations from a low-mass X-ray binary ...
Laguerre-Gaussian (LG) modes are a type of light wave that can carry the external torque of photons as they move through space. They are useful in many fields, from optical communications to super-resolution imaging. Advanced ...
