Le 18 mars, je vous présentais une découverte surprenante, celle d'un trou noir supermassif errant qui laissait derrière lui une traînée de formation d'étoiles (ep. 1469). Moins de deux mois plus tard, une nouvelle étude revient sur cette découverte et montre que Pieter Van Dokkum et ses collaborateurs pourraient s'être complètement trompés dans leur interprétation... La trainée observée pourrait n'être qu'une galaxie vue par la tranche... La nouvelle étude est publiée dans Astronomy&Astrophysics.
