Deep neural network to find hidden turbulent motion on the sun

Scientists developed a neural network deep learning technique to extract hidden turbulent motion information from observations of the sun. Tests on three different sets of simulation data showed that it is possible to infer ...

BESIII reports new measurement of R ratio

The BESIII Collaboration has measured the R ratio in the low center-of-mass (c.m.) energy region. The results were published online in Physics Review Letters.

Protons are likely smaller than previously believed

A few years ago, a novel measurement technique showed that protons are probably smaller than had been assumed since the 1990s. The discrepancy surprised the scientific community; some researchers even believed that the Standard ...

Observing more disk galaxies than theory allows

The Standard Model of Cosmology describes how the universe came into being according to the view of most physicists. Researchers at the University of Bonn have now studied the evolution of galaxies within this model, finding ...

Converting auroral observations into 3D structures

A persistent obstacle to a more complete understanding of Earth's auroral activity is characterizing the structure of auroral arcs in 3D. In situ observations, such as spacecraft transits, can directly observe only a narrow ...
