Researchers observed a supermassive black hole binary in an elliptical galaxy, finding that their prolonged non-merger is due to the inhibitory role of mass and the lack of remaining matter to slow their velocity further. A medication for high cholesterol, cholestyramine, has been found to drastically reduce PFAS levels in the blood, offering a potential treatment for those with major acute exposure to these chemicals. Additionally, a study at the University of Wisconsin-Madison revealed vestigial eyes in daddy longlegs, suggesting an earlier evolutionary diversification than previously believed.
Two supermassive black holes, with a combined mass 28 billion times that of the sun, have been discovered in a fossil galaxy, locked in a gravitational dance preventing them from merging. This finding challenges the theory that supermassive black hole mergers are common, as these are the closest and heaviest black hole pair ever observed. The massive black holes have scoured their galaxy of stars and gas, stalling their collision. The discovery sheds light on the formation and behavior of supermassive black hole binaries after galactic mergers and highlights the potential impact of archival data from telescopes like Gemini North.
The MeerKAT radio telescope has discovered a new radio nebula, dubbed "the Mini Mouse," during observations of the black hole binary GRS 1915+105. The Mini Mouse is a young radio pulsar escaping its birth site and creating a radio nebula with a cometary-like morphology. The pulsar, PSR J1914+1054g, has a spin period of approximately 138.9 milliseconds and dispersion measure of about 418.9 pc/cm3. The distance to the pulsar was estimated to be 26,700 light years. This is the fourth case of a bow shock associated with an escaping pulsar, for which both the pulsar signal and the supernova remnant associated with its birth have been observed.
