The X-ray pulse (white line) is constructed from ‘real’ and ‘imaginary’ components (red and blue dashes) that define the quantum effects. The neural network analyzes the low-resolution measurements (black shadow) to detect the high-resolution pulse and its components.

Image: dwarf galaxy NGC1427A flies through the Fornax Cluster of galaxies and undergoes turbulence that would not have been possible if this galaxy were surrounded by a heavy, stretching dark matter halo, as required by standard cosmology. Opinion more Credit: ESO Dwarf galaxies are small, faint galaxies that can usually be found in galaxy clusters … Read more
Credit: Unsplash/CC0 Public Domain Only a few researchers have studied why American football flies such a unique trajectory, navigating through the air with remarkable precision, but also swerving, swaying, and even drooping as it heads down. Now, ballistics experts at Stevens Institute of Technology have, for the first time, applied their understanding of artillery shells … Read more
