title = "Young rotation-powered pulsars as ultraluminous X-ray sources in star-forming galaxies",
abstract = "Nearby, (mostly) star-forming galaxies have revealed a number of ultraluminous X-ray sources (ULXs) with super-Eddington luminosities. This contribution discusses the possibility that a fraction of them could be young, Crab-like pulsars, the X-ray luminosity of which is powered by rotation. The pulsar birth parameters estimated from radio pulsar data are used to compute the steady-state pulsar X-ray luminosity distribution as a function of the star formation rate (SFR) in the galaxy. The fraction of sources with Lx ≳ 1039 erg/s correlates with the SFR, ranging from ∼ 10\% in optically dull galaxies, to a few in starbursts galaxies. Furthermore, the X-ray luminosity of a few percents of galaxies is found to be dominated by a single bright pulsar with Lx ≳ 1039 erg/s, roughly independently of its SFR. Observational diagnostics that can help distinguish a young pulsar population in ULXs are discussed.",
