Fermi shows that Tycho's star shines in gamma rays

(PhysOrg.com) -- In early November 1572, observers on Earth witnessed the appearance of a "new star" in the constellation Cassiopeia, an event now recognized as the brightest naked-eye supernova in more than 400 years. It's ...

Event displays in particle physics

Subatomic particles are far too tiny to see, so over the years physicists have devised ingenious ways to detect and visualise them, often forming beautiful patterns and pictures in the process. From early experiments with ...

Best of Last Year—The top Phys.org articles of 2016

(Phys.org)—It has been another great year for physics as a team at the University of California, Irvine confirmed the possible discovery of a fifth force of nature—an unknown subatomic particle that, if proven to exist, ...

Researchers simulate important structural elements of the pion

When it comes to describing the fundamental structure and composition of matter, the research field of quantum chromodynamics (QCD) comes into play. With the help of QCD, the strong interaction—one of the four fundamental ...

Physicists confirm existence of new type of meson

(Phys.org) —Physicists in the College of Arts and Sciences at Syracuse University have made several important discoveries regarding the basic structure of mesons—subatomic particles long thought to be composed of one ...

Shocking results of galaxy-cluster collisions

A giant collision of several galaxy clusters, each containing hundreds of galaxies, has produced this spectacular panorama of shocks and energy. The collisions generated shock waves that set off a celestial fireworks display ...

Physicists Begin Quest for 'Higgs' Particle at European Collider

(PhysOrg.com) -- More than two dozen UC San Diego physicists and technicians began their long-awaited quest last week in a research facility below the Swiss-French border to find a hypothetical subatomic particle that they ...
