Over 200 planets have been discovered by the radial velocity technique. Why no black holes? For similar periods, the signal amplitude should be much greater.
TIA.

Black holes are typically found in the centers of galaxies or in binary star systems. They can also be found throughout the universe, but they are usually difficult to detect due to their small size and lack of visible light.
Planet hunters primarily use techniques such as transit photometry and radial velocity to detect planets. These methods are not effective for detecting black holes as they do not emit any light and do not cause any observable changes in the light from surrounding stars.
Yes, black holes can be detected using other methods such as X-ray and radio astronomy. These techniques allow scientists to observe the effects of a black hole's gravitational pull on nearby matter, which can help to indirectly detect their presence.
No, there are currently no known black holes in our solar system. The nearest known black hole, V616 Monocerotis, is located about 3,000 light years away from Earth.
Scientists confirm the presence of a black hole by observing the effects of its gravitational pull on surrounding matter, such as stars or gas clouds. They also look for tell-tale signs, such as X-ray emissions, which can indicate the presence of a black hole. Additionally, scientists can use computer simulations and mathematical models to study the behavior of black holes and confirm their existence.
