Associated Press reporter Seth Borenstein writes that the international consortium behind the Event Horizon Telescope has imaged the supermassive black hole at the center of the Milky Way. To get the picture, eight synchronized radio telescopes around the world had to coordinate so closely “in a process similar to everyone shaking hands with everyone else in the room,” explained research scientist Vincent Fish.
Researchers from the Event Horizon Telescope team, including MIT scientists, have captured the first image of the black hole at the center of the Milky Way, reports Bill Chappell for NPR. “More than 300 researchers collaborated on the effort to capture the image, compiling information from radio observatories around the world,” reports Chappell. “To obtain the image, scientists used observations from April 2017, when all eight observatories were pointed at the black hole.”
Researchers at MIT have developed an automated search tool that can help astronomers identify the echoes emitted by a specific type of black hole, reports Juandre for Popular Mechanics. “The team’s algorithm, which they dubbed the ‘Reverberation Machine,’ pored through data collected by the Neutron Star Interior Composition Explorer, an x-ray telescope mounted to the International Space Station,” writes Juandre. “They identified previously undetected echoes from black hole binary systems in our galaxy.”
MIT astronomers have used light echoes from X-ray bursts to try to map the environment around black holes, reports Dennis Overbye for The New York Times. Prof. Erin Kara then worked with education and music experts to transform the X-ray reflections into audible sound. “I just love that we can ‘hear’ the general relativity in these simulations,” said Kara.
CNN reporter Ashley Strickland writes that MIT astronomers developed an automated search tool and were able to “pin down the locations of eight rare pairings of black holes and the stars orbiting them, thanks to the X-ray echoes they release.”
Vice reporter Becky Ferreira writes that MIT researchers developed a new system, called the Reverberation Machine, to detect the echoes from eight new echoing black hole binaries. “These echoes offer a rarely seen glimpse into the otherworldly surroundings of stellar-mass black holes, which are about five to 15 times the mass of the Sun,” writes Ferreira.
MIT researchers have detected eight echoing black hole binaries in the Milky Way and then converted the black hole X-ray emissions into sound waves, reports Isaac Schultz for Gizmodo. The researchers developed a new tool, dubbed the Reverberation Machine, which “combed satellite data from NICER, a telescope aboard the International Space Station that studies X-ray emissions from sources like black holes and neutron stars, including a weird type of emission known as an ‘echo.’”
Researchers from MIT and the University of Waterloo have developed a new approach aimed at significantly increasing the probability of observing the Unruh effect, reports Juandre for Popular Mechanics. “Now at least we know there is a chance in our lifetimes where we might actually see this effect,” says Prof. Vivishek Sudhir. “It’s a hard experiment, and there’s no guarantee that we’d be able to do it, but this idea is our nearest hope.”
Science Friday host Ira Flatow spotlights how Prof. Scott Hughes has shifted the wavelengths of gravitational waves into the range of human hearing, creating an audible experience that allows listeners to experience the “ripples in space-time made by the tremendous mass of colliding black holes.”
Popular Science reporter Leto Sapunar spotlights the efforts of MIT researchers who are investigating the origins of a fast blue optical transient nicknamed “the Cow.” To research scientist Dheeraj “DJ” Pasham, “this looks like a sign that matter is closely orbiting a ‘newborn’ black hole or a type of neutron star called a magnetar, and the matter shines with x-rays each time it completes a quick orbit,” writes Sapunar.
Newsweek reporter Robert Lea spotlights how MIT researchers traced the source of a bright blue cosmic explosion to the birth of a neutron star or black hole. “We have likely discovered the birth of a compact object in a supernova” says research scientists Dheeraj “DJ” Pasham. “This happens in normal supernovae, but we haven’t seen it before because it’s such a messy process. We think this new evidence opens possibilities for finding baby black holes or baby neutron stars.”
Gizmodo reporter Isaac Schultz writes that MIT astronomers have found that a black hole or neutron star may have been produced by a burst of stellar light, known as “the Cow." “I think the Cow is just the beginning of what is to come,” explains research scientist Dheeraj “DJ” Pasham. “More such objects would provide a new window into these extreme explosions.”
New Scientist reporter Leah Crane writes that astronomers have found evidence that a large stellar explosion detected in 2018 was likely caused by a dying star that gave birth to a neutron star or small black hole. “People have been suspecting that these kind of extreme explosions could be the birth of black holes or neutron stars, but this is a final piece of evidence that I think really settles the case,” says research scientist Dheeraj “DJ” Pasham.
MIT researchers have uncovered evidence that the creation of a new black hole or neutron star caused a strange blue flash of light in space that was detected in 2018, reports Téa Kvetenadze for Forbes. An explanation for the event was elusive until researchers “focused on the X-rays emitted by the flash and found the Cow was producing a pulse of X-rays every 4.4 milliseconds.”
CNET reporter Monisha Ravisetti writes that MIT researchers have found that a super-bright stellar explosion detected in 2018 likely gave rise to a new black hole or neutron star. "Usually, I dare not say 'first time,'" explains research scientist Dheeraj "DJ" Pasham. "But I truly think this is the first time that you have direct confirmation, so to say, that a star dies and you immediately see the baby compact object."
