Did we ever find any signals from an isolated Stellar black hole?

In recent years, scientists have discovered many black holes throughout our galaxy, but the majority of them have been discovered in binary systems. As in the case of a neutron star and a black hole. The light from this binary system is largely gravitationally lensed, which is due to the impact of black holes, which may bend light originating from neutron stars, a phenomena known as gravitational lensing, which is what we are seeing in this binary system. And at night, several telescopes webfocus to observe these kinds of phenomena, including LIGO and VIGRO, which use gravity waves created by these binary systems to observe these kinds of phenomena.

However, there was no way to detect a Stellar black hole in isolation. This is due to the fact that black holes do not emit radiation on their own, so we can't detect them until they're in a system. Recently, physicists discovered a solitary Stellar black hole. This is the first time a single stellar black hole has been discovered. Researchers discovered the mass of this isolated star black hole in this discovery. The mass of a star black hole discovered via gravitational waves is identical to that of a stellar black hole discovered lately. This is solid proof that the isolated stellar black hole is, in fact, a black hole.
