Astronomers using NASA's Chandra X-ray Observatory have discovered a distant quasar with a black hole growing faster than the Eddington limit, shedding light on how supermassive black holes formed early in the universe. The black hole, about a billion times the Sun's mass, is accreting material at a rate 2.4 times the typical maximum, which may explain the rapid emergence of massive black holes shortly after the Big Bang.
Scientists have discovered a supermassive black hole in a distant galaxy devouring matter at 2.4 times the Eddington limit, providing evidence for super-Eddington accretion which may explain how black holes grew so rapidly in the early universe, challenging existing theories about black hole formation and growth.
Astronomers have discovered a supermassive black hole, RACS J0320-35, in the early universe that is growing at over twice the theoretical limit, challenging existing models of black hole growth and cosmic evolution, and prompting new questions about the formation of massive cosmic structures.
Astronomers have discovered a supermassive black hole, RACS J0320-35, in the early universe that is growing at 2.4 times the theoretical Eddington limit, challenging current understanding of black hole growth and suggesting such rapid growth may be more common in the early cosmos.
Astronomers have discovered a supermassive black hole, RACS J0320-35, in the early universe that is growing at 2.4 times the theoretical Eddington limit, challenging current models of black hole growth and raising questions about how such massive objects formed so quickly after the Big Bang.
Scientists have discovered that supermassive black holes in the early universe may have grown rapidly by defying the Eddington limit, a rule that typically restricts their growth. Using X-ray data from the XMM-Newton and Chandra telescopes, researchers found evidence of "super-Eddington accretion," where these black holes consumed matter at rates that should have been impossible, allowing them to reach massive sizes less than a billion years after the Big Bang. This finding could help solve the mystery of how such large black holes formed so quickly.
Astronomers have discovered a black hole, LID-568, in the early universe consuming matter at a rate 40 times greater than the Eddington limit, challenging previous understandings of black hole growth. Using the JWST's Near Infrared Spectrograph, the team observed powerful gas outflows around the black hole, suggesting a rapid feeding mechanism that could explain the existence of massive black holes shortly after the Big Bang. This discovery may provide insights into the mass growth of supermassive black holes and their formation from either light or heavy seeds.
The James Webb Space Telescope has observed a supermassive black hole, LID-568, gaining mass at a rate exceeding the Eddington limit, challenging existing theories of black hole growth. This black hole, existing when the universe was only 11% of its current age, is consuming material at over 40 times the previously believed maximum rate. The discovery suggests a faster method of accretion and calls for further investigation to understand how LID-568 surpasses this theoretical limit.
The James Webb Space Telescope has observed a young black hole, LID-568, consuming matter at a rate 40 times faster than previously thought possible, surpassing the Eddington limit. This discovery could explain why some early black holes are more massive than expected. The telescope's advanced infrared capabilities allow it to study distant cosmic phenomena, providing new insights into the early universe.
Astronomers have discovered the fastest-feeding black hole in the early universe, known as LID-568, which has grown to over seven million solar masses in just 12 million years. This black hole's growth rate exceeds the theoretical Eddington limit, suggesting a super-Eddington accretion process. This finding helps explain how supermassive black holes could form so quickly after the Big Bang. The study, utilizing data from the James Webb Space Telescope and Chandra X-ray Observatory, provides insight into the rapid mass growth of black holes in the early universe.
Astronomers using the James Webb Space Telescope have discovered a supermassive black hole, named LID-568, that is consuming matter at a rate 40 times faster than its theoretical limit, known as the Eddington limit. This finding, observed 1.5 billion years after the Big Bang, suggests that black holes can temporarily exceed their feeding limits, potentially explaining the rapid growth of massive black holes in the early universe. The research, published in Nature Astronomy, provides new insights into black hole growth mechanisms.
Scientists are puzzled by ultraluminous X-ray sources (ULX), celestial objects that shine ten million times brighter than the sun, as they break the Eddington limit, a rule of astrophysics that dictates that an object can only be so bright before it breaks apart. A new study confirms the brightness of a ULX called M82 X-2, which is caused by a pulsating neutron star, and pulls in about 9 billion trillion tons of material per year from a neighboring star. The leading theory to explain ULXs is that super-strong magnetic fields shoot out of the neutron star, squishing the atoms of the matter falling into the star, turning the shape of these atoms from a sphere into an elongated string, which would have a harder time pushing the matter away, explaining why so much matter could fall into the star without breaking apart.
Ultraluminous X-ray sources (ULXs) are breaking the laws of physics by emitting about 10 million times more energy than the sun, which exceeds the Eddington limit. NASA's Nuclear Spectroscopic Telescope Array (NuSTAR) confirmed that one particular ULX, called M82 X-2, is definitely too bright. M82 X-2 is a neutron star that consumes around 1.5 Earths' worth of material each year, siphoning it off of a neighboring star. The research team thinks that the intense magnetic field of the neutron star changes the shape of its atoms, allowing the star to stick together even as it gets brighter and brighter.

Ultra-luminous X-ray sources (ULXs) produce about 10 million times more energy than the Sun, regularly exceeding the Eddington limit by 100 to 500 times. A recent study published in The Astrophysical Journal utilized NASA’s Nuclear Spectroscopic Telescope Array (NuSTAR) to measure a ULX for the first time. Findings confirm that ULXs do indeed break the Eddington limit, potentially due to their strong magnetic fields.
