'Death by a thousand cuts': James Webb Space Telescope figures out how black hole murdered Pablo's Galaxy
Yahoo • • science
Key Points:
- Astronomers using the James Webb Space Telescope (JWST) and ALMA discovered that the young, massive galaxy GS-10578 ("Pablo's Galaxy") was gradually starved of star-forming gas by its central supermassive black hole, effectively causing a slow "death by a thousand cuts."
- The galaxy, seen as it was 3 billion years after the Big Bang, stopped forming stars between 12.5 and 11.5 billion years ago despite its young age, with the black hole expelling gas at speeds up to 2.2 million mph, preventing fresh gas from refilling the star-formation fuel supply.
- ALMA observations found no cold gas remaining in Pablo's Galaxy, indicating a slow starvation
