Three astronomers from the Netherlands have proven that gas that was previously heated near a supermassive black hole and flowed to the outskirts of the galaxy and cooled down, is moving back towards the black hole. While there had been indirect evidence for this theory, this is the first time that the cooled gas moving [...]
Astronomers have used the Atacama Large Millimeter/submillimeter Array (ALMA) to observe a disc around a young star in the Large Magellanic Cloud, a galaxy neighboring ours. It’s the first time such a disc, identical to those forming planets in our Milky Way, has ever been found outside our galaxy. The new observations reveal a massive [...]
The AtLAST conference The Atacama Large Aperture Submillimeter Telescope (AtLAST) design study: results, science, and next steps will take place in Mainz/DE on 21-24 May 2024. This conference aims to bring together all researchers, both scientists and engineers, who are interested in AtLAST and want to support its next steps. Talks will span a broad [...]

An international research team led by Michael Kramer and Kuo Liu from the Max Planck Institute for Radio Astronomy in Bonn/DE have studied a rare species of ultra-dense stars, so called magnetars, to uncover an underlying law that appears to apply universally to a range of objects known as neutron stars. This law gives insight [...]
An international team of astronomers has collaborated to improve the capabilities of the Atacama Large Millimeter/submillimeter Array (ALMA), one of the world’s most powerful telescopes. Scientists from the National Science Foundation’s National Radio Astronomy Observatory (NRAO), the Joint ALMA Observatory, the National Astronomical Observatory of Japan (NAOJ), and European Southern Observatory have achieved the highest [...]
The Event Horizon Telescope (EHT) collaboration has published new results describing for the first time how light from the edge of the supermassive black hole M87* spirals as it escapes the black hole's intense gravity. This signature, known as circular polarisation, is a consequence of the rotation of the electric field in the radio waves. [...]
The RadioAstron mission opened a new window on the universe. Using a network of radio telescopes on Earth and in space, astronomers have captured the most detailed view ever of a jet of plasma shooting from a supermassive black hole at the heart of a distant galaxy. The jet travels at nearly the speed of [...]
An international team of scientists has delved into the heart of the Circinus Galaxy's active galactic nucleus using the Atacama Large Millimeter/submillimeter Array (ALMA). Achieving an unprecedented resolution of about one light-year, the research, led by Takuma Izumi (Assistant Professor at the National Astronomical Observatory of Japan), has illuminated the intricate dance of gas flows [...]
