Feb. 23, 2023 - Research conducted by Dr. Dirk Grupe, 成人抖音破解版 associate professor and chair of the Department of Physics, Geology and Engineering Technology, and colleagues at the Max-Planck-Institute for Radio Astronomy in Germany, has been accepted in the Monthly Notices of The Royal Astronomical Society and the Astrophysical Journal.
The research shows that one of the universe鈥檚 most massive black holes, located at the center of galaxy OJ 287 nearly 5.1 billion light years away, is the size of 100 million solar masses instead of the previously believed 10 billion solar masses.
"I'm incredibly proud that the collaboration between 成人抖音破解版 and Max-Planck-Institute for Radio Astronomy has led to these significant findings that will alter the way we look at this binary black hole system now,鈥 Dr. Grupe said.
The international research group, led by Stefanie Komossa from the Max Planck Institute for Radio Astronomy in Bonn, Germany, and including Dr. Grupe, was able to test crucial binary model predictions using multiple observing tools including the Effelsberg radio telescope and the Neil Gehrels Swift Observatory. There were also collaborators from institutions in China, Chile, Canada and Spain. For the first time, an independent black hole mass determination of the system was performed and the amount of matter in a disk surrounding the black hole could be estimated.
The results show that an exceptionally massive black hole exceeding 10
