Astronomers tracked a star in Andromeda as it dimmed and vanished without the usual fiery explosion, offering rare clues to ...
A supercharged neutrino that smashed into our planet in 2023 may have been spit out by an exploding primordial black hole ...
Supermassive black holes rarely travel alone. Most large galaxies hide one at the center, and when galaxies collide, the two ...
Researchers at Oxford University and the Max Planck Institute for Gravitational Physics (Albert Einstein Institute) are ...
Supermassive black hole binaries form naturally when galaxies merge, but scientists have only confidently observed a very few of these systems that are widely separated. Black hole binaries that ...
For a single supermassive black hole, extremely strong lensing occurs only when a star lies almost exactly along the line of ...
Scientists say an ultra-powerful neutrino once thought impossible may be explained by an exotic black hole model involving a so-called “dark charge.” ...
A faint flash of infrared light in the Andromeda galaxy was emitted at the birth of a stellar-mass black hole – according to a team of astronomers in the US. Kishalay De at Columbia University and the ...
Hypothetical dark matter stars known as "boson stars" could leave telltale ripples across the cosmos, offering researchers a new way to probe the invisible forces shaping the universe. In 2019, a ...
When the researchers calculated the black hole's energy output, they were met with an additional surprise. It's about equal to the energy released by a gamma-ray burst (GRB). Since GRB are the ...
What if the Milky Way’s central “black hole” isn’t a black hole at all? A new model proposes that an ultra-dense dark matter core could mimic its gravitational pull.
Physicists suggest that a single, extraordinarily powerful cosmic signal detected on Earth could be linked to the explosive end of a tiny black hole from the early universe. That signal now stands as ...
