  • Ground-based and satellite observations show that the black hole in the ultraluminous X-ray source P13 has a mass of less than 15 times that of the Sun and displays the properties that typically distinguish ultraluminous X-ray sources from other stellar-mass black holes.

  • Ultraluminous X-ray sources are the most luminous class of black hole located outside the nuclei of active galaxies. They are often associated with shock-ionized nebulae, though with no evidence of collimated jets. Now, however, it is reported that the large nebula S26 in the nearby galaxy NGC 7793 is powered by a black hole with a pair of collimated jets. The jets seem to be 104 times more energetic than the X-ray emission from the core.
