Abstract

Ultraluminous X-ray binaries have challenged our assumptions of extreme accretion rates in X-ray binaries, and impact other subfields of astronomy, such as cosmology, gravitational wave sources and supernov{\ae}. Our understanding of ULXs has changed tremendously over the last 35 years, and we now know that ULXs can be powered by accreting neutron stars as well as black holes, and can be found in a wide range of stellar environments. In this chapter, we introduce the observational techniques used to discover and characterize ULXs, and discuss our current understanding of their unique accretion physics and formation channels.
