Astronomers have discovered a new long-period radio transient, CHIME J1634+44, notable for its circular polarization and accelerating spin period, which may be linked to binary activity or gravitational waves, providing new insights into the nature of such transients.
Scientists studying the first-ever image of a black hole captured by the Event Horizon Telescope (EHT) have discovered twisted magnetic fields around the supermassive black hole at the center of M87. The polarized light observed around the black hole suggests that these magnetic fields may prevent matter from being consumed by the black hole, instead launching it into space as highly collimated jets. The findings provide valuable insights into how black holes consume matter and launch jets outside their host galaxies.
The Event Horizon Telescope (EHT) collaboration has published new findings revealing the strong magnetic fields near the supermassive black hole M87*. By analyzing the circular polarization of light escaping the black hole's intense gravity, researchers gained insights into the magnetic field and high-energy particles surrounding the black hole. These results support earlier observations that the magnetic field near M87* is powerful enough to prevent nearby matter from being consumed by the black hole. The Atacama Large Millimeter/submillimeter Array (ALMA) played a crucial role in providing data and calibration for these measurements.
Scientists at Los Alamos National Laboratory have developed a new quantum light source that generates circularly polarized single photons without the need for an external magnetic field. By stacking two atomically thin materials and creating nanometer-scale indentations, the researchers were able to control the polarization state of the emitted photons. This breakthrough could have significant implications for quantum cryptography and communication, as it combines the generation of single photons with the ability to introduce polarization, paving the way for encoding quantum information into the photon stream.
