Recent research led by Caltech has redefined Compact Symmetric Objects as having short lifespans, not because they are young, but due to their compact and short-lived jets powered by tidal disruption events, offering new insights into their lifecycle and interactions with supermassive black holes. Credit: SciTechDaily.comA new investigation into an obscure class of galaxies known as Compact Symmetric Objects, or CSOs, has revealed that these objects are not entirely what they seem.
In the new studies, the team reviewed literature and past observations of more than 3,000 CSO candidates, verifying 64 as real and identifying an additional 15 CSOs. All these objects had been previously observed by the National Radio Astronomy Observatory’s Very Long Baseline Array , funded by the National Science Foundation , and some had been observed by other high-resolution radio telescopes.
Cosmic objects called Compact Symmetric Objects likely form when a single, massive star wanders too close to a supermassive black hole and is shredded to pieces. The process, highlighted in this animation, results in fierce bipolar jets that last up to 5,000 years. Credit: B.
