Kollision im All doch kein Beweis für Dunkle Materie?Studie .. legt neue Daten vor, die das gängige Modell in Frage stellen

".. Bullet-Cluster galt bislang als Beweis für die Existenz Dunkler Materie. .. Beobachtungen auch mit einer Alternativ-Erklärung vereinbar, .."https://www.uni-bonn.de/de/neues/kollision-im-all-doch-kein-beweis-fuer-dunkle-materie

Surface brightness discontinuities in radio halos - insights from the #MeerKAT #GalaxyCluster Legacy Survey: https://arxiv.org/abs/2302.07881 ("For the #BulletCluster, we find excellent agreement between the locations of the 4 radio discontinuities detected and the X-ray edges. [...] We conclude that radio halos are shaped by dynamical motions in the ICM and that they often display surface brightness discontinuities, which appear to be co-located with edges in the thermal gas emission.")
