Astronomers Spot a Giant Bow Shock Around a Fast-Moving Galaxy
Key Takeaways
- RAD-BAARG appears to show a giant bow shock nearly 1.8 million light years across.
- Researchers think the galaxy is moving through cluster gas faster than sound travels in that medium.
- Its distorted jets and arc-like radio emission make it unlike typical symmetric radio galaxies.
- The object was identified through the LOFAR Two-metre Sky Survey, which is sensitive to faint radio structures.
