Understanding how the universe transitioned from darkness to light with the formation of the first stars and galaxies is a key turning point in the universe’s development, known as the Cosmic Dawn. However, even with the most powerful telescopes, we can’t directly observe these earliest stars, so determining their...

Kavli Fellow James Alvey and collaborators have recently found new methods to put a fundamental limit on the mass of dark matter. A widely used argument suggests that the de Broglie wavelength of dark matter particles must be smaller than the size of the galaxies they inhabit. This requirement has typically implied that...

The Simons Observatory (SO) has completed the installation of its Large Aperture Telescope (LAT) near the summit of Cerro Toco in the Atacama Desert of northern Chile. The telescope joins the observatory’s three Small Aperture Telescopes (SAT) at the site. Together, the telescopes will collect the most precise measurements...

The size and spin of black holes can reveal important information about how and where they formed, according to new research. The study, co-authored by Dr Isobel M. Romero-Shaw (Herchel Smith Fellow at the University of Cambridge), tests the idea that many of the black holes observed by astronomers have merged multiple...
