Weighing OJ 287 and the project MOMO

IPAC News • February 23rd, 2023

An international research group led by Stefanie Komossa from the Max Planck Institute for Radio Astronomy in Bonn, Germany, and including Seppo Laine from Caltech/IPAC, presents important new results on the galaxy OJ 287, based on the most dense and longest radio-to-high-energy observations to date. The scientists were able to test crucial binary model predictions using multiple observing tools including the Effelsberg radio telescope and the Neil Gehrels Swift Observatory. 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.
