Finding X-rays coming from one of the little red dots discovered by the James Webb Space Telescope could be the key to answering what these weird objects truly are.
…
A newly discovered object may be a key to unlocking the true nature of a mysterious class of sources that astronomers have found in the early universe in recent years. A “X-ray dot” found by NASA’s Chandra X-ray Observatory could explain what the hundreds or potentially thousands of these objects are. A paper describing the […]
“With the James Webb Space Telescope now revealing more supermassive black holes in the early universe, this mechanism may help bridge the gap between theory and observation.”
…
Astronomers have discovered that jets from a cannibalistic black hole are erupting with the power of 10,000 suns.
Gravitational waves may have provided the first tantalizing evidence of tiny primordial black holes born during the Big Bang, which could account for dark matter.
…
“It is fascinating that an active galactic nucleus can change its brightness so dramatically over such a short period of time.”
…
Did primordial black holes born during the Big Bang swallow the universe’s antimatter, allowing matter to dominate the cosmos?
…
The research could shed light on how black holes vomit out matter and how this influences their home galaxies.
