Schwarze Löcher sind gefräßig: In großen Mengen saugen sie Materie aus Gaswolken oder Sternen in ihrer Umgebung auf. Während die einfallende "Nahrung" immer schneller in den Schlund hineinspiralt, wird sie zunehmend dichter und auf Temperaturen von Millionen Grad Celsius aufgeheizt. Bevor die Materie schließlich verschwindet, sendet sie ungeheuer intensive Röntgenstrahlung ins All. Der "letzte Schrei" stammt von Eisen, das neben anderen Elementen in der Materie enthalten ist. Was dabei passiert, haben Forscher des Heidelberger Max-Planck-Instituts für Kernphysik gemeinsam mit Kollegen des Helmholtz-Zentrums Berlin an der Synchrotron-Röntgenquelle BESSY II untersucht.
