Primordial black holes (PBHs), possibly formed shortly after the Big Bang, may be experiencing explosive events across the universe. A recent study led by theoretical physicists Dr Marco Calzà and…
Recent discoveries indicate that the universe may harbour significantly more feeding supermassive black holes than previously estimated. These colossal entities, each with a mass ranging from millions to billions of…
A recent study of black hole jets from NASA's Chandra X-ray Observatory has identified bright formations or "knots" in these jets, with each showing unexpected variations in speed. This analysis,…
NASA's Neil Gehrels Swift Observatory has detected a unique signal from two enormous black holes, locked in a cosmic dance that disturbs a dense gas cloud at the centre of…
A recent cosmic census has revealed an unexpected threefold rise in active black holes within dwarf galaxies, creating the most extensive database of intermediate-mass black holes recorded to date. This…
Recent studies, published in Physical Review D on September 16 and 17, have proposed that microscopic black holes may be present within the solar system, potentially affecting the paths of…
Astronomers have been perplexed by the existence of supermassive black holes detected during the universe's earliest phases, just a few hundred million years after the Big Bang. Recent findings, as…
A supermassive black hole located at the center of a distant galaxy has been observed turning back on after a period of dormancy, emitting jets of hot gas into space.…
A study led by the University at Buffalo has proposed that evidence of primordial black holes (PBHs), formed in the early universe, could be found in both cosmic and terrestrial…
Ultramassive black holes, defined as cosmic entities surpassing 10 billion solar masses, may have an upper limit, according to a study led by Dr Priyamvada Natarajan from Yale University's Department…
