We are surrounded by intergalactic puzzles . They last our existence and, with each new study, we completely change our way of thinking about the Universe. The “wheel of knowledge” doesn’t stop moving, does it? We have to try to follow the new researches to understand where the data analysis is going. Including news: a mysterious black hole has been discovered in the heart of a spiral galaxy. According to Einstein’s theory of relativity, it would not be possible for a supermassive black hole to have a disk of matter around it. The astronomical spectrum weighs approximately 250 million times more than the Sun. It is contained in the galaxy NGC 3147, found about 130 million light years away in the constellation Draco. This discovered black hole defies Einstein’s law.
Furthermore, the intergalactic object is apparently “starving”! Its condition is interconnected by the lack of material to feed. Thus, the light emitted by the object at the center of NGC 3147 mimics the behavior of a supermassive black hole at the centers of much more active galaxies.
Opportunity to test Einstein’s theories
The disk of material, which surrounds the black hole, offers a unique opportunity to test Albert Einstein’s theories of relativity. We have an intense challenge ahead of us. This disk is so deeply embedded in the intense gravitational field that the light emitted by the gas disk is modified. At least according to Einstein’s theories. This gave astronomers a unique view of the dynamic processes at work near a black hole.
“This is an intriguing glimpse into a disk very close to a black hole. The approach is such that the speeds and intensity of the gravitational attraction are affecting the way we see photons of light,” said Stefano Bianchi. He is the first author of the study , which was supported by the University of Roma Tre in Italy. An international team of researchers made the discovery, including experts from the University of California, Santa Barbara and Johns Hopkins University.
To support the studies, the researchers used the imaging spectrograph instrument (Hubble Space Telescope). The diagnostic tool splits light from an object into its many individual wavelengths. In this way, you can determine the speed, temperature and other characteristics of the object with very high accuracy. The Hubble telescope also observed that the material in the disc revolved around the black hole at more than 10% the speed of light.
At such extreme speeds, the gas appears to glow as it travels to Earth. Subsequently, it darkens as it moves away from our planet. This effect is known as relativistic radiation. Hubble’s observations also show that the gas is buried deep in a gravity well. The discovered black hole definitely defies Einstein’s law. “We’ve never seen the effects of general and special relativity in visible light so clearly,” said team member Marco Chiaberge.
