Starke Magnetfelder sind offenbar schon kurz nach dem Urknall entstanden

Astrophysiker zeigen Magnetfeldverstärkung anhand dreidimensionaler Computersimulationen

(PresseBox) (Hamburg, )
Unter Beteiligung des Hamburger Astrophysikers Prof. Dr. Robi Banerjee hat eine internationale Forscherkooperation herausgefunden, dass starke Magnetfelder wahrscheinlich bereits kurz nach dem Urknall im Universum vorhanden waren. Damit könnten die Wissenschaftler erklären, woher die beobachteten Magnetfelder in Galaxien und zwischen den Galaxien stammen und welchen Einfluss sie im Universum haben. Bislang wurden die Magnetfelder in vielen Berechnungen ignoriert. Die Arbeiten unter Leitung des Heidelberger Sternforschers Dr. Christoph Federrath wurden an der Ecole Normale Supérieure in Lyon (Frankreich) sowie den Universitäten Heidelberg, Hamburg und Göttingen durchgeführt. Am 9. September 2011 werden die Forschungsergebnisse in der Online-Ausgabe der "Physical Review Letters" veröffentlicht.
