HIGHLIGHTS

  • who: Georgios Antoniou and colleagues from the Nottingham Centre of, Nottingham , RD, UK School of Mathematical Sciences, University of Nottingham, University Park, Nottingham , RD, UK have published the Article: Probing Modified Gravity Theories with Scalar Fields Using Black-Hole Images, in the Journal: Universe 2023, 9, 147. of /2023/
  • what: The authors focus the attention on (EsGB) with three well-motivated couplings including the dilatonic and Z2 symmetric cases. The authors demonstrate that the black-hole 3 of 30 shadow bounds from Sagittarius A* can indeed impose restrictions on the parameter space or on the . . .
