Orbital Decay in M82 X-2
(2022-10-05)
M82 X-2 is the first pulsating ultraluminous X-ray source discovered. The luminosity of these extreme pulsars, if isotropic, implies an extreme mass transfer rate. An alternative is to assume a much lower mass transfer ...
The Variability Behavior of NGC 925 ULX-3
