Measuring of the Compact Objects' Parameters by Analysis of their Shadow
Vassil K. Tinchev
The following work presents a sufficiently general method for finding the parameters that characterise self-gravitating compact objects when their shadow contour is explicitly set.…
On the shadow of rotating traversable wormholes
Galin Gyulchev, Petya Nedkova, Vassil Tinchev +1
We revisit the shadow of rotating traversable wormholes discussing the role of the wormhole throat in the shadow formation. For certain classes of wormholes the throat serves as a…
The Shadow of Generalized Kerr Black Holes with Exotic Matter
Vassil K. Tinchev
We explore the shadow of certain class generalized Kerr black holes, which are non vacuum solutions of the Einstein equations with exotic matter. The images depend on the angular m…
On the common points of two families of -spheres in the flat dimensional space, each of which passes through the vertexes of a given -simplex
Vassil K. Tinchev
Let two distinct -simplexes be given in an Euclidean or pseudo-Euclidean dimensional space as each is defined by the coordinates of its vertexes. We consider the two…
Possible imprints of cosmic strings in the shadows of galactic black holes
Vassil K. Tinchev, Stoytcho S. Yazadjiev
We examine the shadow cast by a Kerr black hole pierced by a cosmic string. The observable images depend not only on the black hole spin parameter and the angle of inclination, but…
The Shadow of a Rotating Traversable Wormhole
Petya G. Nedkova, Vassil Tinchev, Stoytcho S. Yazadjiev
We explore the shadow of certain class of rotating traversable wormholes within classical general relativity. The images depend on the angular momentum of the wormhole, and the inc…
