Imaging black holes

01 APRIL 2018 The Event Horizon Telescope will combine data from a worldwide network of radio telescopes to image the shadow that a black hole casts on the surrounding plasma. Within months of the publication of Albert Einstein’s general relativistic field equations in 1915, Karl Schwarzschild had derived the equations’ first nontrivial solution—the black hole spacetime. Ever since then, the physics and astronomy communities have had a love–hate relationship with black holes. It took almost half a century before they…

Making the ultimate darkness visible

In effort to image black hole, a chance to rule on Einstein BY Colleen Walsh; Harvard Staff Writer DATE: November 3, 2016 Being an astrophysicist and father of two is no easy task. Just ask Dimitrios Psaltis. On a recent morning, the University of Arizona professor of astronomy and physics toggled between a recipe for French pancakes and a series of complex computer simulations tracing the outline of a black hole. “Life goes on,” said Psaltis, the 2016–2017 Shutzer Fellow at Harvard’s Radcliffe Institute…
