Phoenix cluster is cooling faster than expected

With increasingly advanced data, Michael McDonald and colleagues study a galaxy cluster bursting with new stars. Fernanda Ferreira | School of Science | MITNovember 20, 2019 From the very beginning, it was clear that the Phoenix cluster was different from other galaxy clusters. When assistant professor of physics Michael McDonald looked at the first image […]

New research on giant radio galaxies defies conventional wisdom

Conventional wisdom tells us that large objects appear smaller as they get farther from us, but this fundamental law of classical physics is reversed when we observe the distant universe. OCTOBER 25, 2019 by Michelle Ulyatt, University of Kent Astrophysicists at the University of Kent simulated the development of the biggest objects in the universe to […]

Putting the “bang” in the Big Bang

Physicists simulate critical “reheating” period that kickstarted the Big Bang in the universe’s first fractions of a second. Jennifer Chu | MIT News OfficeOctober 24, 2019 As the Big Bang theory goes, somewhere around 13.8 billion years ago the universe exploded into being, as an infinitely small, compact fireball of matter that cooled as it […]

Stormy cluster weather could unleash black hole power and explain lack of cosmic cooling

This so-called “cooling flow” puzzle has plagued astrophysicists for more than 25 years. OCTOBER 17, 2019 by Dr Robert Massey, Royal Astronomical Society “Weather” in clusters of galaxies may explain a longstanding puzzle, according to a team of researchers at the University of Cambridge. The scientists used sophisticated simulations to show how powerful jets from supermassive […]

Data-mining for dark matter

Tracy Slatyer hunts through astrophysical data for clues to the invisible universe. Jennifer Chu | MIT News Office August 15, 2019 When Tracy Slatyer faced a crisis of confidence early in her educational career, Stephen Hawking’s “A Brief History of Time” and a certain fictional janitor at MIT helped to bolster her resolve. Slatyer was 11 […]
