Astronomers using NASA’s Chandra X-ray Observatory have discovered two supermassive black holes with powerful jets, which are being illuminated by the leftover glow from the big bang. The study, published in The Astrophysical Journal, provides a rare glimpse into the early universe and sheds light on how these massive objects interacted with their surroundings.
The black holes, located 11.6 billion and 11.7 billion light-years away from Earth, are surrounded by swirling disks of hot gas that are fueling the growth of galaxies. The jets, which can stretch over 300,000 light-years in length, are blasting away from the black holes at incredible speeds – up to 99% of the speed of light.
Researchers used a novel statistical method to separate the effects of jet speed and viewing angle on detection rates. By running simulations that account for relativistic selection effects, they were able to determine the most probable viewing angles for the jets, which are about 9 degrees and 11 degrees respectively.
This study is significant not only because of its rarity but also because it provides insight into how scientists can better detect and analyze these elusive objects. The Chandra X-ray Observatory’s advanced technology and sharp X-ray vision allowed researchers to capture this phenomenon, even from such great distances.
The discovery was presented by Jaya Maithil at the 246th meeting of the American Astronomical Society in Anchorage, Alaska, and is also being published in The Astrophysical Journal.
