Astronomers have taken a closer look at the relatively nearby Messier 87 (or M87) galaxy to investigate the jet of its active galactic nucleus (AGN). The new research, described in a paper published July 31 on arXiv.org, delivers important insights into the parameters of the jet, which could improve the understanding of AGNs in general.
