Passionategeekz June 15th news, a research team from the Harvard-Smithsonian Center for Astrophysics announced this week at the 246th American Astronomical Society meeting in Alaska that they used Chandra X-ray Observatory and Very Large Array (VLA) observation data to discover two supermassive black hole jets with X-ray brightness equivalent to 10 trillion suns combined.
According to reports, these jets were formed 3 billion years after the birth of the universe. Thanks to the afterglow of the Big Bang, we are still clearly visible tens of billions of light years away. Its jet length is 300,000 light-years (Passionategeekz Note: The diameter of the Milky Way is 105,700 light-years).
They originate from 11.6 billion light-years away (J1610+1811) and 11.7 billion light-years away (J1405+0415), respectively, of which the J1610+1811 quasar jet particles reach 92%-98% of the light speed, and the J1405+0415 quasar jet particles reach 95%-99% of the light speed. The single jet energy is equivalent to half of the total radiation energy of accreted matter.
“These jets convert the first generation of light in the universe into high-energy jets,” said Jaya Maithil, a postdoctoral fellow at the Harvard-Smithsonian Center for Astrophysics. “The electrons in the jets hit the cosmic microwave background (CMB) photons at near-light speeds, increasing their energy to the X-ray band. The CMB density in the early days of the universe was a hundred times higher than today, making jets tens of billions of light years still observable.”
His research confirmed that black hole activity in the early universe far exceeded expectations, and related papers have been accepted by the Journal of Astrophysics. “Questars are like cosmic time capsules, and understanding them can understand their impact on the evolution of the host galaxy,” Maitir said.
