Bright gamma ray burst confounds models of black hole birth
March 28, 2023
Last October, following one of the brightest flashes of gamma rays ever observed in the sky, telescopes around the world captured a wealth of data from an event that is thought to herald the collapse of a massive star and the birth of a black hole. Raffaella Margutti, associate professor of astronomy and of physics at the University of California, Berkeley, notes that the data demonstrated that our models of such events are woefully inadequate.

Were galaxies much different in the early universe?
January 24, 2023
An array of 350 radio telescopes in the Karoo desert of South Africa is getting closer to detecting “cosmic dawn” — the era after the Big Bang when stars first ignited and galaxies began to bloom. Joshua Dillon, a research scientist in the University of California, Berkeley’s Department of Astronomy is lead author on a new paper describing a twofold increase in the sensitivity of the Hydrogen Epoch of Reionization Array (HERA).
