Description
ULXs are extra-galactic X-ray binaries with X-ray luminosities in excess of 10
I will show the result from the analysis of all the X-ray data of the Cartwheel galaxy, a spectacular example of collisional ring galaxy which hosts the largest number of ULXs for a single galaxy. I will also present the long term variability characteristics of a sample of ULXs observed by Swift.
I will discuss my findings in the context of black hole and neutron star variability.
