Astrophysics

Frank and Peggy Taplin Member George N. Wong, Visitor Lia Medeiros, and Professor James Stone, all from the Institute's School of Natural Sciences, have developed an innovative technique to search for black hole light echoes. Their novel method, which will make it easier for the mass and the spin of black holes to be measured, represents a major step forward, since it operates independently of many of the other ways in which scientists have probed these parameters in the past.

Why are some stars brighter than others? Why are some redder or bluer? A plot from a recent research paper by Hsiang-Chih Hwang, Member in the School of Natural Sciences, which addresses this question, has been selected as the Gaia Space Telescope's Image of the Week.

Scott Tremaine, Professor Emeritus in the School of Natural Sciences, has received an honorary doctorate from the University of Waterloo in recognition of numerous seminal contributions to the field of astrophysics, notably "establishing the theory that supermassive black holes are at the core of galaxies."

Sara Seager, Long-Term Member (1999–2002) in the School of Natural Sciences, has been announced as one of the winners of the 2024 Kavli Prize in Astrophysics. Seager was presented with the award for "ground-breaking work" on the discovery and characterization of exoplanets and their atmospheres.

Uddipan Banik, Member in the School of Natural Sciences, has received the Dirk Brouwer Memorial Prize for his Ph.D. thesis, titled "Pushing the Frontiers of Non-Equilibrium Dynamics of Collisionless and Weakly Collisional Self-Gravitating Systems." 

A new image from the Event Horizon Telescope collaboration, which includes George Wong, Frank and Peggy Taplin Member in the School of Natural Sciences, has uncovered strong and organized magnetic fields spiraling from the edge of the supermassive black hole at the center of the Milky Way. 

This article from ACSR Discovery profiles computational work by James Stone, Professor in the School of Natural Sciences, and his colleagues, which has revealed details about how matter falling into black holes and the energy released from them impacts the evolution of the universe.

A pair of astronomers, including Itai Linial, Member (2022–23) in the School of Natural Sciences, "have discovered a handful of supermassive black holes that are associated with bursts of X-rays that recur every few hours or days."
