First Results from the Major XMM-Newton, Chandra and NuSTAR Campaign on the NGC 1313 Galaxy
Abstract
Throughout 2017 we undertook a major, multi-epoch observing campaign on the NGC 1313 galaxy, combining XMM-Newton (800 ks), Chandra (500 ks) and NuSTAR (500 ks). NGC 1313 is notable for hosting two extreme (Lx,peak ~ 1e40 erg/s) ultraluminous X-ray sources (ULXs), X-1 and X-2. Furthermore, X-1 is the first ULX in which absorption in an ultrafast (~0.25c) outflow was been detected. I will present early results from this large coordinated campaign. These include the unusual broadband continuum variability seen in X-1 and the changes/variability seen in its extreme wind, and also the likely discovery of another member of the elusive population of ULX pulsars, remarkable sources in which extreme super-Eddington accretion must be occuring.
