Berkeley astronomers question future of Geoffrey Marcy after harassment charge

A well-known astronomer resigned from the University of California, Berkeley, where he had been a professor for 16 years after an investigation found he sexually harassed several female students, two top administrators said. The university immediately accepted Professor Geoffrey Marcy’s resignation, according to a Wednesday statement from Chancellor Nicholas B. Dirks and Executive Vice Chancellor …



ALMA unveils rapid star formation in distant galaxies

ALMA unveils rapid star formation in distant galaxies

Researchers have found that galaxies forming stars at extreme rates 9 billion years ago were more efficient than average galaxies today. The question astronomers have been asking is whether such starbursts in the early universe were the result of having an overabundant gas supply, or whether galaxies converted gas more efficiently. In general, the larger a …



Young stars’ flickering light reveals remarkable link with matter-eating black holes

Young stars’ flickering light reveals remarkable link with matter-eating black holes

An international team of astronomers, including Dr Simon Vaughan from the University of Leicester’s Department of Physics and Astronomy, has discovered a previously unknown link between the way young stars grow and the way black holes and other exotic space objects feed from their surroundings. The study, ‘Accretion-induced variability links young stellar objects, white dwarfs, …



The golden anniversary of black-hole singularity

The golden anniversary of black-hole singularity

When a star collapses forming a black hole, a space-time singularity is created wherein the laws of Physics no longer work. In 1965 Sir Roger Penrose presented a theorem where he associated that singularity with so-called ”trapped surfaces” that shrink over time. That hypothesis -one of the results of the general theory of relativity- is …
