Rochester Institute of Technology professors have developed a faster, more accurate way to assess gravitational wave signals and infer the astronomical sources that made them. Their method directly ...

Asking what existed before the Big Bang is often dismissed as meaningless, since traditional physics breaks down when pushed that far back in time. Yet a new paper published in Living Reviews in ...

Numerical relativity uses supercomputers to simulate conditions occuring at the start of the universe, answering some of the biggest questions, like, how did the universe begin?

Research teams on both sides of the Atlantic have shown that precise modeling of the universe and its contents will change the detailed understanding of the evolution of the universe and the growth of ...

Simulating the merger of black holes is no small scientific feat. For one thing, it requires a lot of computing horsepower — the kind you can get only from a supercomputer. It also involves solving ...

The quality and quantity of current and forthcoming cosmological datasets call for both analytical and numerical modelling of the dynamics of nonlinear gravitational matter based on general relativity ...

Precision cosmology: the Large Synoptic Survey Telescope will soon be scanning the heavens. (Courtesy: LSST) A powerful numerical code that uses Einstein’s general theory of relativity to describe how ...

Rogue black holes kicked from their galactic lairs are among the surprising predictions made by physicists using powerful computers to solve Einstein's equations of general relativity. David Appell ...

We’re often told it is “unscientific” or “meaningless” to ask what happened before the big bang. But a new paper by FQxI cosmologist Eugene Lim, of King's College London, UK, and astrophysicists Katy ...

The student will develop and use numerical relativity simulations to model fundamental physics in strong gravity regimes. The goal is to understand the behaviour of non linearities around black holes ...
