Supermassive black hole discovered by new method 30 billion times the size of the sun
英ダラム大学の天文学者が率いるチームが観測史上最大級の超大質量ブラックホールを発見した
A team led by astronomers from Durham University in the UK has discovered one of the largest supermassive black holes ever observed.
Published in a paper published in the Monthly Bulletin of the Royal Astronomical Society
論文によれば、この星の質量は太陽の３００億倍以上
According to the paper, the mass of this star is more than 30 billion times that of the sun
Using images from NASA’s Hubble Space Telescope, the team confirmed the mass through methods of gravitational lensing and supercomputer simulations.
重力レンズ効果とは遠くの天体から来る光が途中の銀河によって曲げられる現象を指す
Gravitational lensing refers to the phenomenon in which light coming from a distant celestial body is bent by a galaxy in the middle
These galaxies act like magnifying lenses
チームは想定するブラックホールの質量を変えながら宇宙から届く光をシミュレーション
The team simulated light arriving from space while changing the mass of the assumed black hole
It is said that the number of times reached several hundred thousand times
According to the society, this is the first time a black hole has been discovered using such a method.
