Black Hole Jets Observed in Early Universe by Qian Zhuo Telescope
Table of Contents
The NASA Qian Zhuo X-ray Space Telescope has detected powerful black hole jets in the distant universe. These jets interact with the cosmic microwave background (CMB), causing them to appear brighter.

Astronomers used the Qian Zhuo telescope and the Karl G. Jansky Very Large Array (VLA) to study black holes during the “Noon of the Universe,” approximately 3 billion years after the Big Bang.Research indicates that galaxies and supermassive black holes grew more rapidly during this period than at any other time in the universe’s history. Scientists aim to understand how black hole jets influenced their surroundings during this critical epoch.
The team identified two black holes, located 11.6 billion and 11.7 billion light-years from Earth, with jets extending over 300,000 light-years. Electrons ejected from the black hole jets collide with photons from the CMB, boosting the photons’ energy into the X-ray band, which the Qian Zhuo telescope can detect.
VLA data was used to compare jet characteristics. While the Qian Zhuo telescope’s jet detection aligned with VLA electromagnetic wave radiation observations, continuous radio wave jets matching the X-ray jet length were not observed.this discrepancy arises as electrons generating radio waves have a shorter lifespan than those producing X-rays through CMB interaction. Consequently, enhanced X-ray radiation is observed without corresponding radio wave radiation.
Based on electromagnetic wave band observations, researchers calculated the velocity of one jet (J1405+0415) at 95% to 99% of the speed of light, and the other jet (J1610+1811) at 92% to 98% of the speed of light. The team also measured the magnetic field and found that these magnetic pairs interact with the CMB, representing typical X-ray jet cases. The findings were presented at the 246th meeting of the American Astronomical Society and published in “The Astrophysical Journal.”
Did You No? The “Noon of the Universe” saw the most rapid growth of galaxies and supermassive black holes in cosmic history.
The Event Horizon Telescope, a global network of observatories, has also contributed significantly to black hole research. In 2019,it captured the frist direct image of a black hole’s shadow,located in the galaxy M87,approximately 55 million light-years away. This groundbreaking achievement confirmed predictions made by Einstein’s theory of general relativity and provided valuable insights into the behavior of matter near black holes [Source: Event Horizon Telescope].
The james Webb Space Telescope (JWST), launched in December 2021, is also playing a crucial role in studying black holes. With its unprecedented infrared sensitivity, JWST can peer through dust clouds and observe the faintest and most distant galaxies, potentially revealing new details about the formation and evolution of supermassive black holes in the early universe [Source: NASA JWST].

Pro Tip: Studying black hole jets helps scientists understand the impact of black holes on their surrounding environments during critical periods in the universe’s history.
The study of black holes and their jets is crucial for understanding the evolution of galaxies and the universe as a whole. By observing these phenomena at different stages of cosmic history, scientists can piece together a more complete picture of how these enigmatic objects have shaped the cosmos.

Understanding Black Holes: An Evergreen Viewpoint
Black holes are regions of spacetime with such strong gravitational effects that nothing, not even particles and electromagnetic radiation such as light, can escape from inside it. The theory of general relativity predicts that a sufficiently compact mass can deform spacetime to form a black hole. The boundary of the region from which no escape is possible is called the event horizon.Although crossing the event horizon has enormous effect on the fate of the object crossing it,it appears to have no locally detectable features.
Supermassive black holes (SMBHs), with masses ranging from millions to billions of times the mass of the Sun, are believed to exist at the center of most galaxies. These SMBHs play a critically important role in galaxy evolution, influencing the formation of stars and the distribution of gas and dust within their host galaxies. The study of black hole jets, like those observed by the Qian Zhuo telescope, provides valuable insights into the complex interactions between SMBHs and their surrounding environments.
