Physicists “cautiously optimistic” about CERN evidence for new funda
Posted by Shubham Ghosh Roy in categories: cosmology, particle physics
If the finding really is the result of new fundamental particles then it will finally be the breakthrough that physicists have been yearning for for decades.
When CERN’s gargantuan accelerator, the Large Hadron Collider (LHC), fired up ten years ago, hopes abounded that new particles would soon be discovered that could help us unravel physics’ deepest mysteries. Dark matter, microscopic black holes, and hidden dimensions were just some of the possibilities. But aside from the spectacular discovery of the Higgs boson, the project has failed to yield any clues as to what might lie beyond the standard model of particle physics, our current best theory of the micro-cosmos.
So our new paper from LHCb, one of the four giant LHC experiments, is likely to set physicists’ hearts beating just a little faster. After analyzing trillions of collisions produced over the last decade, we may be seeing evidence of something altogether new – potentially the carrier of a brand new force of nature.

Astronomers See Black Hole Jets Blaze 16x Wider Than The Full Moon in Our Sky
Posted by Genevieve Klien in category: cosmology
Astronomers have captured a breathtaking radio wave image, showing our closest radio active black hole spewing out massive jets of plasma that span more than 16 times the size of the full moon in our sky.
The supermassive black hole in question is located in the center of the galaxy Centaurus A around 12 million light-years away.
The black hole has a jaw-dropping mass of around 55 million Suns but isn’t visible in the image. It would be located within the small empty patch in the center of the two butterfly wing-like lobes.

Why the Webb telescope will stare into the Milky Way’s supermassive black hole
Posted by Atanas Atanasov in category: cosmology
The telescope will join the worldwide effort.
NASA’s James Webb Space Telescope (JWST) successfully launched on Saturday, and it will soon be ready to reveal parts of the universe that have never been seen before including a very large, but very broody, cosmic object at the center of the galaxy.

Black Holes of All Shapes and Sizes in Largest Catalog of Gravitational Wave Events Ever Assembled
Posted by Genevieve Klien in categories: cosmology, physics
The largest catalog of gravitational wave events ever assembled has been released by an international collaboration that includes Penn State researchers. Gravitational waves are ripples in space time produced as aftershocks of huge astronomical events, such as the collision of two black holes. Using a global network of detectors, the research team identified 35 gravitational wave events, bringing the total number of observed events to 90 since detection efforts began in 2015.
The new gravitational wave events were observed between November 2019 and March 2020, using three international detectors: The two Advanced Laser Interferometer Gravitational-Wave Observatory (LIGO
The Laser Interferometer Gravitational-Wave Observatory (LIGO) is a large-scale physics experiment and observatory supported by the National Science Foundation and operated by Caltech and MIT. It’s designed to detect cosmic gravitational waves and to develop gravitational-wave observations as an astronomical tool. It’s multi-kilometer-scale gravitational wave detectors use laser interferometry to measure the minute ripples in space-time caused by passing gravitational waves. It consists of two widely separated interferometers within the United States—one in Hanford, Washington and the other in Livingston, Louisiana.
