Physics & Mathematics

The diagram illustrates the process of multiparticle scattering mediated by twisted paths endowed with orbital angular momentum (OAM). The number of photons in each twisted path is measured and correlated using photon-number-resolving (PNR) detectors.

The hidden centre of galaxy NGC 1052 (artist’s impression). In this artist’s impression we are nearing the supermassive black hole at the centre of galaxy NGC 1052. Here, material collects in a spinning disk before falling into the black hole, and magnetic fields build up which may help launch the galaxy’s powerful jets.

A green turtle comes up for air. Like many air-breathing marine megafauna, green turtles optimise their swim depth during migration to minimise the cost of transport, travelling at around three body-depths beneath the surface in order to avoid creating waves whilst maximising horizontal distance travelled (Picture © R. D. and B. S. Kirkby).

By uncovering the cause of strong optical anisotropy in Bi-based cuprates, this study allows for more precise exploration of the mechanisms behind high-temperature superconductivity, bringing us closer to achieving room-temperature superconductors.

Using the deepest X-ray image ever made with Chandra of Centaurus A, astronomers have found an unusual mark from the giant black hole’s powerful jet striking an unidentified object in its path. A patch of V-shaped emission connected to a bright source of X-rays is located close to the path of the jet from the supermassive black hole (highlighted in the inset). The arms of the “V” are at least about 700 light-years long. In this image, low, medium, and high-energy X-rays from Chandra are colored pink, purple, and blue respectively.
