If you have a question about this talk, please contact Dr George Lansbury.

Ultra-luminous X-ray pulsars (ULXPs) are a relatively new class of accreting neutron stars, that can reach luminosities up to a factor of 500 above their Eddington limit. These extreme luminosity and implied accretion rate challenges our current understanding of accretion flows onto compact objects. I will give a brief overview over the known ULX Ps and discuss their physical properties, in particular their pulse period evolution and their magnetic field. I will highlight open questions and paths forward to answer them.
