f(R) Gravity in an Ellipsoidal Universe
Cemsinan Deliduman, Oguzhan Kasikci, Vildan Keles Tugyanoglu
We propose a new model of cosmology based on an anisotropic background and a specific theory of gravity. It is shown that field equations of gravity in a Bianchi type…
Gravitational Lensing in Weyl Gravity
Oguzhan Kasikci, Cemsinan Deliduman
We calculate the deflection angle of light from a distant source by a galaxy cluster in Weyl's conformal gravity. The general method of calculation is first applied to calculate th…
Flat Galactic Rotation Curves from Geometry in Weyl Gravity
Cemsinan Deliduman, Oguzhan Kasikci, Baris Yapiskan
We searched for a resolution of the flat galactic rotation curve problem from geometry instead of assuming the existence of dark matter. We observed that the scale independence of…
