The complex puzzle known as little red dots has become more complete since their initial discovery by NASA's James Webb Space Telescope in 2022. Now a particular little red dot's spectrum is helping connect many of the pieces.
A study in the Journal of Cosmology and Astroparticle Physics explores how a machine-learning strategy known as transfer learning could dramatically reduce the computational cost of searching for new physics beyond the standard ...
From the air, you see it only through the constant jolt, tilt, and shudder of the low-flying Cessna aircraft. The landscape of the Llanos de Moxos, northern Bolivia, appears as a disconnected patchwork of open grassland savannahs, ...
NASA's plans to return astronauts to the moon through the Artemis program and ultimately send humans to Mars highlight just how far space exploration has come. Yet while the moon and Mars remain compelling destinations filled ...
A new theoretical study may have cracked one of the most puzzling discoveries of the James Webb Space Telescope (JWST): Little Red Dots, spotted across the early universe. The paper, posted to the arXiv preprint server on ...
A supermassive black hole lies at the heart of every galaxy, including the Milky Way. When a black hole is active, it pulls material in as a whirlpool of high-temperature gas and dust. As this cosmic material piles up and ...
Gravitational waves are tiny ripples in spacetime. Their first direct detection in 2015 marked a revolutionary moment in astronomy. Today, we have a thorough understanding of signals that travel far from their sources through ...
The most distant, nearly invisible dormant black hole has been detected and "weighed" by an international team of astronomers that includes researchers from UCL. The study, published in Science, identified a dormant black ...
Galactic collisions are events of breathtaking proportions. The supermassive black holes (SMBHs) at their centers plunge into a chaotic orbital dance that eventually coalesce into a single remnant. On their way to that point, ...
Black holes, regions in space where gravity is so strong that nothing can escape, have been widely studied over the past decades, due to their unique and intriguing properties. Einstein's theory of general relativity predicts ...
