双黑洞在致密天体附近“跳舞”——上海科学家突破性发现为揭开双黑洞形成之谜提供全新线索

Core Insights - The research team led by Han Wenbiao from the Shanghai Astronomical Observatory has discovered that binary black hole mergers may occur near a third compact object, providing new clues to the formation of binary black holes [2][4] - This finding is based on the analysis of gravitational wave event GW190814, which features two black holes with a mass difference of nearly ten times, suggesting they may have interacted with a supermassive black hole in a "trio" configuration [2][3] Group 1 - The international gravitational wave detection consortium has recorded over 100 gravitational wave events since the first detection in 2015, with the majority originating from binary black hole mergers [2] - The research team constructed a gravitational wave waveform template that includes line-of-sight acceleration to capture unique signatures in the gravitational wave signals [3] - The results strongly support the existence of line-of-sight acceleration in the gravitational wave event GW190814, indicating the presence of a third compact object during the merger [3]
