From Forbes, Jan. 19, 2021: Fermilab scientist Don Lincoln contextualizes the discovery of the most distant (and therefore oldest) supermassive black hole found thus far, which is 10 trillion times brighter than our sun.
The NOvA experiment, best known for its measurements of neutrino oscillations using particle beams from Fermilab accelerators, has been turning its attention to measurements of cosmic phenomena. In a series of results, NOvA reports on neutrinos from supernovae, gravitational-wave events from black hole mergers, muons from cosmic rays, and its search for the elusive monopole.
Black holes live up to their name. They emit no light and they’re usually very far away. This makes it hard to take pictures of them, and indeed, some people claimed that they might not exist. But that’s no longer true. In episode 19 of Subatomic Stories, Fermilab scientist Don Lincoln tells us how we are quite sure that black holes are real.
In recent years, scientists have found ways to study black holes, listening to the gravitational waves they unleash when they collide and even creating an image of one by combining information from radio telescopes around the world. But our knowledge of black holes remains limited. So scientists are figuring out how to make do with substitutes — analogs to black holes that may hold answers to mysteries about gravity and quantum mechanics.
From ABC7: Fermilab scientist Brad Benson talks about the South Pole Telescope’s role part in the Event Horizon Telescope. Scientists behind the Event Horizon Telescope recently revealed the first image ever made of a black hole, depicting its hot, shadowy edges where light bends around itself in a cosmic funhouse effect. Assembling data gathered by eight radio telescopes around the world, astronomers created the picture showing the violent neighborhood around a supermassive black hole, the light-sucking monsters of the universe theorized by Einstein more than a century ago and confirmed by observations for decades.
From WBEZ’s Morning Shift, April 10, 2019: WBEZ interviews Fermilab scientist Brad Benson about the recent unveiling of the first ever photograph of a black hole. The Event Horizon Telescope, a collaboration between more than 200 scientists using telescopes from around the world, shot photographs of a supermassive black hole in the galaxy M87.
