Researchers from the Institute of Cosmos Sciences of the University of Barcelona (ICCUB) and the University of Jaén have described, for the first time, the structure of a Z-shaped galactic microquasar. This astronomical object is considered to be a small-scale version of a winged radio galaxy, so far considered among the distant potential emitters of gravitational waves. The main conclusion of the study, published in Nature Communications, is that not all winged radio galaxies are sources of gravitational waves.
