For 50 years, the research community has been hunting unsuccessfully for the so-called Odderon particle. Now, a Swedish-Hungarian research group has discovered the mythical particle with the help of extensive analysis of experimental data from the Large Hadron Collider at CERN in Switzerland. In 1973, two French particle physicists found that, according […]

ANIMATION Scientists of the PRISMA+ Cluster of Excellence analyze data from the gravitational wave observatory NANOGrav. The NANOGrav Collaboration recently captured the first signs of very low-frequency gravitational waves. Prof. Pedro Schwaller and Wolfram Ratzinger analyzed the data and, in particular, considered the possibility of whether this may point towards new […]

The electron antineutrino that created the Glashow resonance event traveled quite a distance before reaching IceCube. This graphic shows its journey; the blue dotted line is the antineutrino’s path.

An photograph shows the surface portion of the IceCube Neutrino Observatory. (Image credit: Martin Wolf/IceCube/NSF) This event was predicted in 1960, but never seen before in the real world. The most remote particle detector on Earth has detected the most energetic antimatter particle ever: a single ultralight particle that smacked into the Antarctic ice […]

Sometimes the sun spits out high-energy particles which slam into the Earth, potentially disrupting our sensitive electronics. New research has found that these particles originate in the plasma of the sun itself, and are trapped there by strong magnetic fields. When those fields weaken, the particles blast out. The sun […]

A visualization of the Glashow event recorded by the IceCube detector. Each colored circle shows an IceCube sensor that was triggered by the event; red circles indicate sensors triggered earlier in time, and green-blue circles indicate sensors triggered later. This event was nicknamed “Hydrangea.” Credit: IceCube Collaboration The South Pole […]

Neutrinos are notoriously finicky particles.  Hundreds of trillions pass through a person’s body every second, yet they hardly seem to interact with anything (though they actually do a lot).  Even more hard to find are the “high energy” neutrinos that are believed to be formed as the outcome of some of the most violent […]

The illustration traces the path of the beam as it passes through the copper radio frequency quadrupole, the black dipole magnet, and the slitted measuring system, and onto the particle detector. The beam’s structural complexity increases when measured at progressively higher resolutions. Credit: ORNL/Jill Hemman A high-intensity accelerator beam is […]

Simulation of a collision in the Large Hadron Collider, producing the Higgs boson. © 1997-2021 CERN (CC-BY-SA-4.0) Credit: University of Granada An international team of scientists proposes a new heavy particle with properties similar to those of the Higgs boson. Unlike the Higgs boson, discovered at CERN’s Large Hadron Collider in […]

On the left is a simulated image in which intracluster light is visible as a diffuse haze between discrete peaks of brightness — the galaxies. In observations, as seen in the right, this intracluster light component is largely drowned in noise. Credit: Left image: Jesse Golden-Marx; simulation by The IllustrisTNG. […]
