Using the Very Long Baseline Interferometry (VLBI) technique, astronomers have probed the parsec-scale jet of a neutrino-emitting blazar known as TXS 0506+056. Results of the new study, presented May 1 on arXiv.org, shed ...
Blazars are a special kind of rare active galactic nuclei. They are currently the most likely candidates for high-energy neutrinos. Their relativistic jets may be the origin area of super-high-energy cosmic rays and neutrinos.

One of the greatest mysteries in astrophysics these days is a tiny subatomic particle called a neutrino, so small that it passes through matter—the atmosphere, our bodies, the very Earth—without detection.

A trio of researchers from CSIC-Universitat de València and Universitat de Barcelona has used data from the IceCube detector in Antarctica to measure Earth's mass. In their paper published in the journal Nature Physics, ...
The universe should be a predictably symmetrical place, according to a cornerstone of Einstein's theory of special relativity, known as Lorentz symmetry. This principle states that any scientist should observe the same laws ...
