Revisiting Flat Rotation Curves in Chern-Simons Modified Gravity
Waleed El Hanafy, Mahmoud Hashim, G. G. L. Nashed
We revisit slow rotating black hole (BH) solutions in Chern-Simons modified gravity (CSMG) by considering perturbative solution about Schwarzschild BH. In particular, the case when…

Quadratic Rastall Gravity: from low-mass HESS J1731-347 to high-mass PSR J0952-0607 pulsars
Waleed El Hanafy
Similar to Rastall gravity we introduce matter-geometry nonminimal coupling which is proportional to the gradient of quadratic curvature invariants. Those are mimicking the conform…
