M51 ULX-7: super-orbital periodicity and constraints on the neutron star magnetic field
G. Vasilopoulos, S. K. Lander, F. Koliopanos +1
In the current work we explore the applicability of standard theoretical models of accretion to the observed properties of M51 ULX-7. The spin-up rate and observed X-ray luminosity…

NGC 300 ULX1: spin evolution, super-Eddington accretion and outflows
G. Vasilopoulos, M. Petropoulou, F. Koliopanos +4
NGC300 ULX1 is an ultra-luminous X-ray pulsar, showing an unprecedented spin evolution, from about 126 s to less than 20 s in only 4 years, consistent with steady mass accretion ra…
