Black Hole, Furthest Known, Affirmed from 500 Million Years Post Big Bang Event
In a groundbreaking discovery, astronomers have confirmed the presence of a supermassive black hole at the core of a distant galaxy, CAPERS-LRD-z9, which is the earliest and most distant confirmed supermassive black hole known. This remarkable find, made possible by the James Webb Space Telescope (JWST), sheds new light on the early universe and challenges our understanding of black hole growth.
A Unique Object for Studying Early Black Hole Evolution
CAPERS-LRD-z9 belongs to a new class of galaxies known as "Little Red Dots." These compact, red, and very bright galaxies formed around 13.3 billion years ago, during the Cosmic Dawn, an epoch when the first stars and galaxies were taking shape. The black hole at the core of CAPERS-LRD-z9 is estimated to be up to 300 million times the mass of the Sun, a size that was reached within just 500 million years after the Big Bang.
Rapid Growth Explained
The black hole's rapid growth can be attributed to several key factors. Firstly, the high gas density (~10^10 particles per cubic centimeter) in the region around the black hole provided abundant material to fuel its mass accumulation. Secondly, the presence of broad emission lines from hydrogen gas moving at thousands of kilometers per second indicates an active galactic nucleus (AGN), where the black hole is accreting matter at a high rate, converting gravitational energy into intense radiation.
Modeling suggests that the black hole may be surrounded by a shell of dusty gas, which can both shield and funnel material inward to sustain rapid growth. The JWST's spectroscopy has been instrumental in measuring the gas velocities and redshift (z=9.288) to confirm the black hole's presence and estimate its mass at about 38 million solar masses (potentially up to 316 million).
Implications for Early Black Hole Growth
The study suggests that early black holes might have started out far more massive than current models predict. This finding could revolutionize our understanding of the early universe, as it challenges our understanding of black hole growth and evolution. The team's findings, published in The Astrophysical Journal Letters, could provide valuable insights into early black hole growth and evolution.
The discovery of the black hole in CAPERS-LRD-z9 has shown that supermassive black holes can appear surprisingly early in cosmic history and grow quickly. However, the exact mechanisms behind this rapid growth are still under investigation, with scenarios like direct collapse of massive gas clouds early on or rapid mergers being considered. Regardless, the evidence currently points to very efficient accretion processes in dense primordial environments as the main mechanism for the black hole in CAPERS-LRD-z9.
In conclusion, the discovery of the black hole in CAPERS-LRD-z9 represents a significant milestone in our understanding of the early universe. Its rapid growth is primarily attributed to the abundant dense gas in its young host galaxy fueling intense accretion soon after the Big Bang, allowing it to reach supermassive scale within a few hundred million years. The JWST has revolutionized our understanding of the earliest universe, enabling us to look back in time to the hundreds of millions of years after the Big Bang and study the evolution of the universe in unprecedented detail.
