FRANKFURT. Black holes are considered cosmic gluttons, from which not even light can escape. That is also why the images of black holes at the center of the galaxy M87 and our Milky Way, published a ...

The image of supermassive black hole Sagittarius A * was created using data from the Event Horizon Telescope Collaboration. At the same time several telescopes, including the Chandra X-ray Observatory ...

Abstract: This paper investigates the error-based eventtriggered model predictive control (ET-MPC) problem for nonlinear discrete-time systems with additive disturbances. A novel event-triggering ...

ABSTRACT: The images collected by the EHT of objects M87* and SgrA* show darkened, but not black areas. So that the immediate identification with supermassive black holes remains questionable.

Abstract: Dear Editor, This letter studies the event-triggered adaptive horizon distributed model predictive control problem for discrete-time coupled nonlinear systems with additive disturbances. By ...

A novel imaging technique used for the first time on a ground-based telescope has helped a UCLA-led team of astronomers to achieve the sharpest-ever measurement of a star's surrounding disk, revealing ...
