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…
Absence of Relativistic Stars in f(T) Gravity
Cemsinan Deliduman, Baris Yapiskan
In this work we investigate the structure of neutron stars in modified f(T) gravity models. We find that, unlike the f(R) models, the equations of motion put a rather strict constr…
Properties of Solutions in 2+1 Dimensions
M. Hortacsu, H. T. Ozcelik, B. Yapiskan
We solve the Einstein equations for the 2+1 dimensions with and without scalar fields. We calculate the entropy, Hawking temperature and the emission probabilities for these cases.…
