A new unified model of dark matter and dark energy in 5-dimensional gravity
M. Bousder, Z. Sakhi, M. Bennai
We propose a new unified model that describes~dark energy and dark matter in the context of gravity using a massive scalar field in five dimensions. The scalar field is co…

Deflection Angle and Shadow Behaviors of Quintessential Black Holes in arbitrary Dimensions
A. Belhaj, M. Benali, A. El Balali +2
Motivated by M-theory/superstring inspired models, we investigate certain behaviors of the deflection angle and the shadow geometrical shapes of higher dimensional quintessential b…

Thermal Image and Phase Transitions of Charged AdS Black Holes using Shadow Analysis
A. Belhaj, L. Chakhchi, H. El Moumni +2
We investigate the relations between the black hole shadow and charged AdS black hole critical behaviour in the extended phase space. Using the thermo-shadow formalism built-in [1]…
