In a paper (link is external) published today in the European Physical Journal C, the ATLAS Collaboration reports the first high-precision measurement at the Large Hadron Collider (LHC) of the mass of the W boson.

This is one of two elementary particles that mediate the weak interaction – one of the forces that govern the behaviour of matter in our universe.

The reported result gives a value of 80370±19 MeV for the W mass, which is consistent with the expectation from the Standard Model of Particle Physics, the theory that describes known particles and their interactions.

Science joke.

A physicist sees a man standing on a ledge ready to jump. He shouts out "Stop!!!!! You have so much potential!!!!"

Landmark report blows popular anti-vaxxer myth out of the water.

A major new study has revealed no link between autism and the measles, mumps and rubella (MMR) vaccine.

Re: Science thread --- first images of a black hole
« Reply #373 on: April 11, 2019, 03:09:03 AM »
A black hole and its shadow have been captured in an image for the first time, a historic feat by an international network of radio telescopes called the Event Horizon Telescope (EHT). EHT is an international collaboration whose support in the U.S. includes the National Science Foundation.

Using the Event Horizon Telescope, scientists obtained an image of the black hole at the center of galaxy M87, outlined by emission from hot gas swirling around it under the influence of strong gravity near its event horizon.

A black hole is an extremely dense object from which no light can escape. Anything that comes within a black hole’s “event horizon,” its point of no return, will be consumed, never to re-emerge, because of the black hole’s unimaginably strong gravity. By its very nature, a black hole cannot be seen, but the hot disk of material that encircles it shines bright. Against a bright backdrop, such as this disk, a black hole appears to cast a shadow.   

The stunning new image shows the shadow of the supermassive black hole in the center of Messier 87 (M87), an elliptical galaxy some 55 million light-years from Earth. This black hole is 6.5 billion times the mass of the Sun. Catching its shadow involved eight ground-based radio telescopes around the globe, operating together as if they were one telescope the size of our entire planet.

There's a good explanation of it here: https://www.youtube.com/watch?v=S_GVbuddri8

And more info here: https://twitter.com/AstroKatie/status/1115965419666464768

This pic gives a better perspective on how huge this black hole is.




They also collected data of the black hole at the centre of our Milky Way galaxy but it's not as clear as M87.
