Das staubige Herz einer aktiven Galaxie

Astronomen beobachten eine dichte Scheibe und einen hellen Schlot im Zentrum des Circinus-Sternsystems

(PresseBox) (München, )
Forscher um Konrad Tristram vom Bonner Max-Planck-Institut für Radioastronomie haben die bisher detailreichste hochaufgelöste Infrarotstudie von der Umgebung eines extrem massereichen schwarzen Lochs im Zentrum eines aktiven Sternsystems veröffentlicht. Die Beobachtungen der Circinus-Galaxie zeigen zum ersten Mal, dass der von der zentralen Energiequelle beleuchtete Staub in zwei voneinander getrennten Komponenten auftritt. Dabei ist eine verbogene Staubscheibe im Innern von großräumig verteiltem Staub umgeben. Letzterer dürfte den überwiegenden Anteil der Abschattung in der Nähe des zentralen schwarzen Lochs verursachen.

In den Kernregionen von aktiven Galaxien verschluckt ein zentrales supermassereiches schwarzes Loch große Mengen an Materie. Diese wird auf ihrem "Sturzflug" in
