An X-ray look at the heart of powerful quasars
Researchers have observed the X-ray emission of the most luminous quasar seen in the last 9 billion years of cosmic history, known as SMSS J114447.77-430859.3, or J1144 for short. The new perspective sheds light on the inner workings of quasars and h…
Astronomers reveal the largest cosmic explosion ever seen
A team of astronomers led by researchers at the University of Southampton has uncovered the largest cosmic explosion ever witnessed. The explosion is more than ten times brighter than any known supernova. The research is published in Monthly Notices…
Hidden supermassive black holes brought to life by galaxies on collision course
Astronomers have found that supermassive black holes obscured by dust are more likely to grow and release tremendous amounts of energy when they are inside galaxies that are expected to collide with a neighbouring galaxy. The new work, led by researc…
Light-bending gravity reveals one of the biggest black holes ever found
A team of astronomers have discovered one of the biggest black holes ever found, taking advantage of a phenomenon called gravitational lensing. The findings are published in Monthly Notices of the Royal Astronomical Society. The team, led by Durham…
Redness of Neptunian asteroids sheds light on early Solar System
Asteroids sharing their orbits with the planet Neptune have been observed to exist in a broad spectrum of red colour, implying the existence of two populations of asteroids in the region, according to a new study by an international team of research…
Galaxy changes classification as jet changes direction
A team of international astronomers have discovered a galaxy that has changed classification due to unique activity within its core. The galaxy, named PBC J2333.9-2343, was previously classified as a radio galaxy, but the new research has revealed ot…
Royal Astronomical Society announces all journals to publish as open access from 2024
The Royal Astronomical Society (RAS) has today announced that all journals published by the Society will be Open Access (OA) from January 2024. This move will enable everyone in the global community to have free, immediate, and unrestricted access to…
New discovery sheds light on very early supermassive black holes
Astronomers from the University of Texas and the University of Arizona have discovered a rapidly growing black hole in one of the most extreme galaxies known in the very early Universe. The discovery of the galaxy and the black hole at its centre pro…
Distant galaxy mirrors the early Milky Way
A galaxy has been discovered that mirrors the very early version of our home galaxy, the Milky Way. The galaxy, dubbed ‘The Sparkler’, is embedded in a system of globular clusters and satellite galaxies, and appears to be swallowing them as it grows.…
Astronomers confirm age of most distant galaxy with oxygen
A new study led by a joint team at Nagoya University and the National Astronomical Observatory of Japan has measured the cosmic age of a very distant galaxy. The team used the ALMA radio telescope array to detect a radio signal that has been travelli…
Next Generation Interferometric Image Reconstruction: call for papers
The new generation of radio telescope arrays, such as the upcoming Square Kilometre Array (SKA) and its existing pathfinders MeeRKAT and ASKAP (radio), as well as the Event Horizon Telescope (EHT) and the Very Large Telescope Interferometer (VLTI) (m…
Milky Way found to be more unique than previously thought
Is the Milky Way special, or, at least, is it in a special place in the Universe? An international team of astronomers has found that the answer to that question is yes, in a way not previously appreciated. A new study shows that the Milky Way is too…
