Dynamical boson stars (2012, background): “These images allow the study of so-called BH shadows, that is, the gravitational lensing and redshift effect due to the BH on the radiation from background sources [218].”
The shape of the black hole photon ring: A precise test of strong-field general relativity (2020, background): “For example, the equatorial approach predicted the presence of discrete sub-rings [13] later found in more realistic models [14].”
Silhouette of M87*: A new window to peek into the world of hidden dimensions (2019, background): “The shadow is formed when photons with small impact parameter originating from a source of electromagnetic radiation behind the BH gets trapped by its gravity [48–55] and hence fail to reach the observer.”
Lensing by Kerr black holes (2019, neutral): “Photons executing of order one orbit or more contribute a sequence of highly demagnified images near the critical curve [15, 16, 20, 21].”
Influence of quintessence dark energy on the shadow of black hole (2020, background): “Actually, this orbit is circular and unstable [11].”
