Electron Beams in Circular or Spiral Motion Emit Vortex Photons

IMS Researchers and their colleagues have theoretically and experimentally demonstrated that vortex photons are emitted by a high-energy electron that moves circularly or spirally, in the complete wavelength range from the radio-wave to the gamma-rays.

Scientists Make Best Measurement of Raw Materials that Fuels Star Formation in the Universe

The international Spitzer Adaptation of the Red-sequence Cluster Survey collaboration based at the University of California, Riverside has combined observations from several of the world’s most powerful telescopes to carry out one of the largest studies yet of molecular gas – the raw material which fuels star formation throughout the universe – in three of the most distant clusters of galaxies ever found, detected as they appeared when the universe was only four billion years old.

Spiral Arms Allow Astronomers and School Children to Estimate Mass of Hidden Black Hole

Astronomers from Swinburne University of Technology, Australia, and the University of Minnesota Duluth, USA, have provided a way for armchair astronomers, and even primary school children, to merely look at a spiral galaxy and estimate the mass of its hidden, central black hole.

Researchers Use New Technique to Reduce Vortex Motion and Enhance Superconductors' Properties

Researchers have made the first direct visual observation and measurement of ultra-fast vortex dynamics in superconductors. Their technique, detailed in the journal Nature Communications, could contribute to the development of novel practical applications by optimizing superconductor properties for use in electronics.

Physicists Successfully Observe 'Second Face' of Nickel-66 Nuclei

To some degree of approximation, atomic nuclei look like spheres which in most cases are distorted to a greater or lesser extent. When the nucleus is excited, its shape may change, but only for an extremely brief moment, after which it returns to its original state.

Physicists Reveal Direct Connections Between Largest Cosmic Structures and Small Particles

Physicists are capitalizing on a direct connection between the largest cosmic structures and the smallest known objects to use the universe as a "cosmological collider" and investigate new physics.

Researchers Perform First Ever Quantum-Mechanical Simulation of Ultracold Chemical Reaction

Researchers have performed the first ever quantum-mechanical simulation of the benchmark ultracold chemical reaction between potassium-rubidium (KRb) and a potassium atom, opening the door to new controlled chemistry experiments and quantum control of chemical reactions that could spark advances in quantum computing and sensing technologies.

First Collaborative Exoplanet Search Teams Discover New Hot Jupiter

A new ‘Hot Jupiter’ exoplanet has been discovered by scientists led by a team at Keele University. The new giant planet was jointly discovered by a WASP/KELT survey alliance, making this the first time an exoplanet has been discovered between two planet search teams.

NASA's Gamma-Ray Telescopes Observe a Trap that Concentrates the Highest-Energy Cosmic Rays

A collective study on the data obtained from NASA's Fermi Gamma-ray Space Telescope and the High Energy Stereoscopic System (H.E.S.S.), a ground-based observatory in Namibia, reveals that the center of the Milky Way comprises of a "trap" that is capable of concentrating some of the highest-energy cosmic rays, among the fastest particles present in the galaxy.

Scientists Use Van Allen Probes Mission to Understand Dynamics of Plasma Waves

Space is not empty, nor is it silent. While technically a vacuum, space nonetheless contains energetic charged particles, governed by magnetic and electric fields, and it behaves unlike anything we experience on Earth.
