Dr. Ingram and colleagues from Amsterdam, Cambridge, Southampton and Tokyo observed the black hole H 1743-322, which was exhibiting a four-second QPO at the time. They watched it for 260,000 seconds with XMM-Newton, and also observed it for 70,000 seconds with NASA's NuSTAR X-ray observatory (artist's impression).
