La collaboration Event Horizon Telescope (EHT) a utilisé son réseau de radiotélescopes de la taille de la Terre pour sonder la structure magnétique du noyau de la galaxie NGC 1275 qui est aussi la source radio 3C 84 (ou Perseus A), et qui contient l’un des trous noirs supermassifs actifs les plus proches de notre voisinage. Ces nouveaux résultats fournissent un nouvel aperçu de la manière dont les jets des trous noirs supermassifs sont lancés, révélant que les champs magnétiques dominent la gravité. L'étude est parue dans Astronomy&Astrophysics.
