James Webb Space Telescope Identifies Massive Black Hole 'BiRD' in Early Universe
Astronomers using the James Webb Space Telescope have discovered 'BiRD,' a supermassive black hole from the early universe, offering new insights into black hole growth during cosmic noon.
Astronomers utilizing the James Webb Space Telescope (JWST) have identified a supermassive black hole, designated 'BiRD' (Big Red Dot), that existed approximately 10 billion years ago during the period known as 'cosmic noon.' This discovery provides valuable insights into the formation and growth of supermassive black holes in the early universe.
BiRD is part of a category of objects termed 'little red dots,' which are compact, red-tinted astronomical entities observed by JWST. Despite its classification, BiRD is substantial, with a mass about 100 million times that of the Sun. It was detected near the quasar J1030+0524, located approximately 12.5 billion light-years from Earth. The research team, led by Federica Loiacono from the National Institute for Astrophysics (INAF), identified BiRD through analysis of images and spectra obtained with JWST's Near-Infrared Camera (NIRCam).
The spectral analysis revealed clear signals of hydrogen and helium, allowing the team to estimate BiRD's distance and mass. These findings suggest that BiRD belongs to the same family as other little red dots, which are considered potential precursors to supermassive black holes. The study also indicates that such objects remained abundant during cosmic noon, challenging previous assumptions about their prevalence during this epoch.
The discovery of BiRD underscores JWST's capability to uncover previously unknown objects in the early universe, opening new avenues for understanding the evolution of supermassive black holes.
