Supermassive black holes are the largest known black holes in the universe, sitting at the center of most large galaxies. They are sometimes described as cosmic monsters because they feed on surrounding gas and dust when ...
Astronomers using the James Webb Space Telescope (JWST) have discovered a stellar bar in GN20, a massive galaxy seen just 1.5 billion years after the Big Bang. The new paper was submitted to the preprint server arXiv on May ...
From satellite imagery to clandestine price reports, a new study draws on North Korea to explore economic activity in opaque regimes and information-scarce regions. North Korea is the blackest of economic black holes. Even ...
Which comes first, the galaxy or the black hole? We don't know, but scientists have long thought it could be the galaxy: Large stars within an existing galaxy consume their fuel and collapse to form black holes, which can ...
Astronomers may have uncovered a hidden supermassive black hole inside the famous Antennae galaxies NGC 4038/4039, a pair of colliding galaxies best known for their spectacular bursts of star formation. The paper outlining ...
On the night of 18 December 2019, a star in our satellite galaxy, the Large Magellanic Cloud, briefly got brighter. Not dramatically nor explosively, just a smooth symmetrical rise and fall in brightness lasting about an ...
Astronomical observations show that the most massive galaxies in the early universe formed approximately three to four billion years after the Big Bang and stopped producing stars very early in cosmic history, around one ...
Mathematicians are challenging the idea that dark energy is responsible for the accelerating expansion of the universe. In a new paper published in Proceedings of the Royal Society A, mathematicians from the University of ...
Astrophysicists think that black hole masses are hierarchical. The largest are supermassive black holes (SMBH) like the one at the center of the Milky Way and other galaxies. Stellar mass black holes are born of collapsing ...
Researchers from the University of Glasgow's Institute for Gravitational Research are celebrating the publication of a vast new treasure trove of gravitational wave detections, hailed as a milestone marking the coming of ...
