Stellar Mass Black Holes and Ultraluminous X-Ray Sources

Understand

We review the likely population, observational properties, and broad implications of stellar-mass black holes and ultraluminous x-ray sources.

• We focus on the clear empirical rules connecting accretion and outflow that have been established for stellar-mass black holes in binary systems in the past decade and a half.
• These patterns of behavior are probably the keys that will allow us to understand black hole feedback on the largest scales over cosmological time scales.
