Once every 10,000 years or so, the center of a galaxy lights up as its supermassive black hole rips apart a passing star. This “tidal disruption event” happens in a literal flash, as the central black...
In 2017, astronomers captured the first image of a black hole by coordinating radio dishes around the world to act as a single, planet-sized telescope. The synchronized network, known collectively as ...
In this talk, I will present the progress of the study on black hole images in our group. The topic is expected to include black hole shadows, images of the accretion disk and jets around a black hole...
Clues to a black hole’s origins can be found in the way it spins. This is especially true for binaries, in which two black holes circle close together before merging. The spin and tilt of the respecti...
Earlier this year, astronomers were keeping tabs on data from the Zwicky Transient Facility, an all-sky survey based at the Palomar Observatory in California, when they detected an extraordinary flash...
In October 2018, a small star was ripped to shreds when it wandered too close to a black hole in a galaxy located 665 million light years away from Earth. Though it may sound thrilling, the event did ...
An international team of more than 300 scientists from 80 institutions has created the first-ever image of the supermassive black hole at the center of our Milky Way galaxy.
Black holes are invisible by nature. Their pull is inescapable, forever trapping any light that falls into their gravitational abyss. But just beyond a black hole’s point of no return, light persists,...
Scattered across our Milky Way galaxy are tens of millions of black holes — immensely strong gravitational wells of spacetime, from which infalling matter, and even light, can never escape. Black hole...
Research done at Cornell has uncovered from gravitation wave data the first potential signs of spin-orbit resonances in binary black holes, a step toward understanding the mechanisms of supernovas and...
Black holes are paradoxically both the simplest and most complex objects in the universe, as shown by the still-mysterious set of laws Stephen Hawking discovered a half-century ago. Resolving this par...
Even the most extreme objects in the universe – including black holes – must obey certain rules.
Event Horizon Telescope scientists, who produced the first image of a black hole, have revealed a new view of the massive object at the center of the M87 galaxy, showing how it looks in polarized...
In 2019, the Event Horizon Telescope Collaboration delivered the first image of a black hole, revealing M87* -- the supermassive object in the center of the M87 galaxy. The EHT team has now used the l...
When a star passes too close to a supermassive black hole, tidal forces tear it apart, producing a bright flare of radiation as material from the star falls into the black hole. Astronomers study the ...
