Is it feasible to perform space VLBI at 230 GHz? Also how does one detect the radio jets at 230 GHz?
Radio astronomy is a branch of astronomy that uses radio waves to study celestial objects in space. It allows us to observe objects that may not be visible in other wavelengths of light, and provides valuable insights into the structure and behavior of these objects.
Black holes emit strong radio signals due to the intense gravitational forces at their event horizons. These signals can be detected using radio telescopes, which can pick up the faint radio waves emitted by the matter falling into the black hole.
Radio astronomy can provide valuable information about the size, mass, and spin of black holes. It can also reveal the surrounding environment, such as the presence of an accretion disk or jets of particles being ejected from the black hole.
By studying black holes through radio astronomy, we can gain insights into the processes that govern the behavior of these massive objects. This, in turn, can help us understand the evolution of galaxies, the formation of structures in the universe, and the fundamental laws of physics.
Some current projects include the Event Horizon Telescope, which aims to capture images of the supermassive black hole at the center of our galaxy, and the Square Kilometre Array, a radio telescope under construction that will have the sensitivity to detect black holes in the early universe. Future projects include the Next Generation Very Large Array, which will have even greater capabilities for studying black holes and other astronomical objects through radio waves.
