Felix Fuerst

XMM-Newton Scientist


Main Research Fields

I am an X-ray astronomer working in the XMM-Newton SOC.  My research intrests are mainly high-mass X-ray binaries (HMXBs) and ultra-luminous X-ray sources (ULXs), in particular all those which host a neutron star. But any accreting compact object is interesting to me, and I also know my way around normal and super-massive black holes. I work on the spectral and timing properties of these objects, including pulsation searches and measuring the magnetic field through cyclotron resonant scattering features. I also care a lot about the donor star and in particular its wind and how the structure of that wind influences the observed X-ray variability.
