Overview
- The international team recorded the outflow during a coordinated 10-day campaign, with XRISM providing the longest continuous view alongside XMM-Newton and five other missions.
- For the first time, astronomers directly saw a high-speed ejection form and accelerate during an X-ray flare, establishing the event’s timing and evolution.
- The wind reached about 60,000 kilometers per second and appeared within roughly a day of the flare as the burst faded.
- Spectra indicate the expelled gas originated near a region about 50 times the black hole’s size in NGC 3783, whose central black hole is roughly 30 million solar masses and 130 million light-years away.
- The findings, published in Astronomy & Astrophysics, point to magnetic reconnection as the most likely launch mechanism and motivate follow-up studies to test how common such events are.
