Chinese space telescope to observe ‘big eaters’
China’s new space telescope will take into account many mysteries of the universe, including “big eaters” – active nuclei of galaxies to the farthest reaches of the universe. Scientists have discovered that almost all galaxies have a black hole with a mass of several million supermassiform to several billion times that of the Sun in the center. With its strong gravitational pull, supermassive black holes gobble up surrounding gas and dust, Xinhua news agency reported.
When a black hole overflows too much, the excess material becomes two jet stream perpendicular to the accretion disk of the black hole, which is like a greedy with an inflated abdomen. The jet stream and the accretion disk of the black hole generators strong enough supermassive x-rays to billion light-years travel. These galaxies have very bright nuclei – so bright that the central region may be brighter than the remaining galaxy. Scientists call them active galactic nuclei.
The hard X-ray modulation of the telescope (HXMT), developed by Chinese scientists, will observe some active galactic nuclei. “Since the active nuclei of galaxies are very far from Earth, our telescope can only detect the brightest,” said Zhang Shuangnan, senior scientist and director of HXMT key Particle Astrophysics Laboratory of the Chinese Academy of Sciences (CASO) . On Monday. The great dining rooms are full of mysteries. Scientists have discovered that the double-jet phenomenon is very common in galaxies with active galactic nuclei, but I do not understand why super-massive black holes can not cover any matter that falls into them.
Black holes are very different black holes of stellar mass, which form when the collapse of very massive stars at the end of their life cycle. Scientists still do not know how to form supermassive black holes and grow, which is a key to understanding the evolution of galaxies. Observing HXMT should help scientists see the central zone near the horizon of events supermassive black holes in the center of active galaxies and gather information on the extremely strong gravitational fields, Zhang added.
