NASA Webb Explores Family Tree of Newly Discovered Distant Objects - NASA Science
Researchers suggest that 'little red dots' are a temporary phase of active supermassive black holes rather than a unique galaxy population. This conclusion stems from analyzing the spiral galaxy WISEA J123635.56+621424.2, nicknamed the 'Saguaro.'
Why it matters
This discovery helps astronomers understand how supermassive black holes and their host galaxies evolve over billions of years.
The details
- The study analyzed spiral galaxy WISEA J123635.56+621424.2, nicknamed the 'Saguaro.'
- Synthetic shifts show that surroundings fade at higher redshifts, creating observational bias.
- Chandra X-ray Observatory detected weak X-ray emission from the Saguaro's nucleus.
