A new theoretical study suggests that while black holes typically merge, they might split under extreme conditions. Researchers found that rapid rotation could bypass thermodynamic barriers, though the window for such an event is narrow. The study, published in Physical Review D, highlights that this is currently a theoretical possibility rather than an observed phenomenon.
Astronomers have identified Blazar OP 313 as the most distant and earliest blazar ever detected, providing a rare glimpse into the universe's high-activity phase. This object features a supermassive black hole emitting plasma jets directly toward Earth, with light that has traveled for 8 billion years. The discovery offers critical insights into the 'cosmic noon' era, a period of intense galaxy formation that occurred roughly 5 billion years after the Big Bang.
NASA's Fermi Gamma-ray Space Telescope has detected an unusual and unexplained signal from deep space while analyzing 13 years of data, challenging scientists' understanding of space rays. The signal, found by chance, is outside our galaxy and has a nearly identical magnitude to one of the oldest gamma-ray features, perplexing researchers. This discovery, detailed in The Astrophysical Journal Letters, could be linked to a cosmic gamma-ray feature observed in 2017, marking a significant and unexpected finding in the realm of gamma-ray astronomy.
