Astrophysicists used the JWST to observe central supermassive black hole for 48 hours total across one year. They found the accretion disk is constantly emitting flares without periods of rest. Shorter, faint flares and longer, bright flares appear to be generated by separate processes.

Astronomers have peered through the atmosphere of a planet beyond the Solar System, mapping its 3D structure for the first time. By combining all four telescope units of the European Southern Observatory’s Very Large Telescope (ESO’s VLT), they found powerful winds carrying chemical elements like iron and titanium, creating intricate weather patterns across the planet’s atmosphere. The discovery opens the door for detailed studies of the chemical makeup and weather of other alien worlds.

Lobster-eye satellite Einstein Probe captured the X-ray flash from a very elusive celestial pair. The discovery opens a new way to explore how massive stars interact and evolve, confirming the unique power of the mission to uncover fleeting X-ray sources in the sky.

Researchers at the University of Oxford, together with colleagues at the UK Science and Technology Facilities Council (STFC) and at several other laboratories, have announced results from a new search at the European X-ray Free Electron Laser (European XFEL) Facility at Hamburg for a hypothetical particle that may make up the dark matter of the Universe. The experiment is described in a study published in Physical Review Letters.

The add-on acoustic black hole (AABH), as a vibration reduction device with light weight, rich modal density, and high damping characteristics, has been extensively studied in the vibro-acoustic control of structures. However, there has been no research on application of AABH in the control of the typically aeroelastic instability phenomenon of a panel in supersonic flow. Meanwhile, the prediction of aerodynamic response and flutter boundary of panel structures with attached AABH presents a complex challenge, requiring a sophisticated numerical strategy. Therefore, establishment of a numerical method for coupled aeroelastic analysis of a panel in supersonic flow with AABH and the performance of AABH in suppression of the panel's aeroelastic instability is of great significance.The add-on acoustic black hole (AABH), as a vibration reduction device with light weight, rich modal density, and high damping characteristics, has been extensively studied in the vibro-acoustic control of structures.
