Astronomers detect signs of wind from Milky Way’s central black hole
Researchers report a cone-shaped cavity in cold gas near Sagittarius A* that they attribute to an outflow of hot gas. The finding follows five years of observations with radio and X-ray telescopes.

Astronomers Detect Only Mild Wind from Milky Way’s Central Black Hole
New observations show a cone-shaped gap near the Milky Way’s central black hole, indicating a hot wind is blowing away cold gas. The findings appear in Astrophysical Journal Letters.

Study Links Heavy Black Holes to Repeated Mergers
A new analysis of 153 gravitational-wave detections found that black holes above roughly 45 solar masses show rapid, misaligned spins consistent with prior mergers. The pattern supports formation inside dense stellar clusters rather than direct stellar collapse.

Astronomers Report Possible Most Massive Pair of Black Holes
Observations of a galaxy 4.4 billion light-years away suggest the presence of two ultramassive black holes with a combined mass 60 billion times that of the sun. The pair, located in a 3,200 light-year star-free void, appears to be spiraling toward a merger.

Physicists Use Particle Physics Link to Study Hawking Radiation
Researchers have applied a mathematical connection known as the double copy to translate Hawking radiation from general relativity into the language of the standard model of particle physics. The approach equates the radiation to a charged particle scattering off a collapsing sph…

Scientists Quantify Energy Output of Black Hole Cygnus X-1 Jets Traveling at Half Light Speed
A new study published in Nature Astronomy has measured the energy produced by the black hole Cygnus X-1, revealing jets that travel at half the speed of light and shine as bright as 10,000 suns. The research combined global radio telescope data to analyze the black hole’s plasma…

Physicists Propose Exploding Primordial Black Holes Explain Matter-Antimatter Asymmetry
Researchers suggest that tiny primordial black holes formed shortly after the Big Bang exploded and produced shock waves that favored matter over antimatter in the early universe. These black holes, with masses around 1,000 kilograms, would have evaporated via Hawking radiation w…
