Black Holes

Feryal Özel, past Member in the School of Natural Sciences (2002–05) and current chair of the School of Physics at Georgia Tech, discusses her work on the recent imaging of a black hole with the Event Horizon Telescope (EHT) collaboration and the...

The unparalleled resolution of the Event Horizon Telescope (EHT) images of the black holes at the center of the M87 galaxy and at the center of our galaxy, called Sagittarius A* (Sgr A*), allows us to test assumptions, predictions, and alternatives to Einstein’s theory of gravity. 

Ahmed Almheiri, past Member (2017–22) in the School of Natural Sciences, has received a 2022 IUPAP Early Career Scientist Award in Particles and Fields “for substantial and impactful contributions to the understanding of black holes and quantum gravity, specifically related to the information paradox and its connection to quantum information theory and quantum error correction.”

"As theorists study black holes and other objects in AdS space, they keep learning Wheeler-esque lessons. One is that the connectivity of space — the ability to get from one place to another — seems to stem from particles on the boundary linked by correlations known as quantum entanglement."

If a picture is worth a thousand words, what might the first horizon-scale image of a black hole tell us? A new paper by researchers from the Event Horizon Telescope (EHT) collaboration, which famously imaged M87’s central black hole, has provided a...
