Strong gravitational lensing around Kehagias-Sfetsos compact objects surrounded by plasma
Sudipta Hensh, Jan Schee, Ahmadjon Abdujabbarov +1
We present the analysis how Hořava gravity and plasma influence the strong lensing phenomena around Kehagias-Sfetsos (KS) black holes. Using the semi-analytical Bozza method of str…

Raychaudhuri equations and gravitational collapse in Einstein-Cartan theory
Sudipta Hensh, Stefano Liberati
The Raychaudhuri equations for the expansion, shear and vorticity are generalized in a spacetime with torsion for timelike as well as null congruences. These equations are purely g…
