An international team of scientists has used new millimeter-wavelength observations to produce an image that shows, for the first time, both the ring-like accretion structure around a black hole, where matter falls into the black hole, and the black hole's associated powerful relativistic jet.

An international team of astrophysicists and cosmologists have submitted a set of five papers, measuring a value for the 'clumpiness' of the universe's dark matter, known to cosmologists as S8, of 0.76, which aligns with values that other gravitational lensing surveys have found in looking at the relatively recent universe - but it does not align with the value of 0.83 derived from the Cosmic Microwave Background.
