The recently discovered galaxy, known as SDSS J011754.86+095819.0, or dE01+09, seems to be one of these "runaway" systems. The study points out that dE01+09 was unique among 751 candidates due to its isolation and lack of recent star formation. According to Paudel's team, dE01+09 was a young, star-forming galaxy when it joined the group several billion years ago. According to the study, strong forces quenched the gas it needed to form new stars about 8.3 billion years ago. The galaxy then kept orbiting within the group until it was probably expelled after a close gravitational encounter with another galaxy some 3.5 billion years ago.
