Abstract

We study a black hole with a blurred mass density instead of a singular one, which could be caused by the noncommutativity of 3-space. Depending on its mass, such object has either none, one or two event horizons. It possesses new properties, which become im-portant on a microscopic scale, in particular, the Hawking temperature does not increase indefinitely as the mass goes to zero, but vanishes instead. Such frozen and extremely dense pieces of matter are a good dark matter candidate. In addition, we introduce an object oscillating between a microscopic black hole and a naked (and blurred) singularity, we call it gravimond.
