What dictates the formation of luminous black hole openParBHclosePar versus neutron star openParNSclosePar X-ray binaries openParXRBscloseParquestionMark Recent studies have shown that some ultraluminous X-ray sources in starburst and high specific star formation rate openParsSFRclosePar galaxies are pulsars comma while low sSFR galaxies such as M31 have a dearth of accreting BHs. These discoveries have challenged our understanding of XRB evolution and the associated accretion processes. We request a 420 ks NuSTAR observation simultaneous with a 50 ks XMM-Newton observation of the starburst galaxy NGC 6946 openParThe Fireworks GalaxyclosePar to characterize the accreting BH and NS populations and investigate the black hole fraction at luminosities below the NS Eddington limit.
