Discovery of a pseudobulge galaxy launching powerful relativistic jets

J. K. Kotilainen, J. Leon Tavares, A. Olguin-Iglesias +4

Supermassive black holes launching plasma jets at close to speed of light, producing gamma-rays, have ubiquitously been found to be hosted by massive elliptical galaxies. Since ell…
