Using the MUSE instrument on ESO’s VLT , a team led by Thomas Collett from the University of Portsmouth in the UK first calculated the mass of ESO 325-G004 by measuring the movement of stars within ...

In 2019, the MAGIC telescopes detected the first Gamma Ray Burst at very high energies. This was the most intense gamma-radiation ever obtained from such a cosmic object. But the GRB data have more to ...

Assistant Professor Haocun Yu is something of a scientific diplomat. In a recent Physical Review Letters publication, she and ...

The mathematics Albert Einstein devised to describe the gravitational workings of the physical Universe in the early 20th century is still holding strong. In one of the biggest tests of general ...

General Relativity (GR), Einstein’s theory of gravitation, underpins our understanding of the large-scale dynamics of the Universe. Over recent decades, rapid advances in observational cosmology have ...

Scientists have used the loudest gravitational-wave signal ever recorded to put Albert Einstein's more than 100-year-old theory of gravity to its toughest test yet — and once again, it passed. The ...

Physicists are close to performing the most accurate tests of Einstein’s ideas about gravity ever undertaken. Their first-of-its-kind experiment involves using two kinds of extremely cold atoms aboard ...

Imagine being able to measure tiny changes in the flow of time caused by Earth’s gravity with atomic clocks atop one of Colorado’s iconic peaks above 14,000 feet. That could soon be a reality thanks ...

For those who watch gravitational waves roll in from the universe, GW250114 is a big one. It's the clearest gravitational wave signal from a binary black hole merger to date, and it gives researchers ...
