Astronomers using the James Webb Telescope think they’ve spotted three ancient and stupendously large stars that could be powered by dark matter, originating around 400 million years after the Big Bang.
Something deep in the heart of the Milky Way galaxy is glowing with gamma radiation, and nobody can figure out for sure what it might be.
It’s a map and time machine rolled into one.
A cosmic analog of tree rings hints at how the bar’s spin slowed over time
International team reveal vast cosmic voids over the Earth’s skies that could challenge Einstein
A mysterious wake of stars, stirred up by a small galaxy that is set to collide with the Milky Way, could be about to unlock the mysteries of dark matter.
Physicists have concluded that some masses of boson particles — members of the things-that-could-explain-dark-matter club — don’t actually exist, meaning the parameters for locating the presumably vast but hypothetical material just became more refined.
On 21 May 2019, from a distance of 7 billion light-years away, our gravitational wave detectors were rocked by the most massive collision yet. From analysis of the signal, astronomers concluded that the detection was the result of two black holes smashing together, weighing in at 66 and 85 times the mass of the Sun respectively.
The Kavli Institute for the Physics and Mathematics of the Universe (Kavli IPMU) is home to many interdisciplinary projects which benefit from the synergy of a wide range of expertise available at the institute. One such project is the study of black holes that could have formed in the early universe, before stars and galaxies were born.
