Galactic Rotation Dynamics in f(T) gravity

Understand

We investigate galactic rotation curves in $f(T)$ gravity, where $T$ represents a torsional quantity.

• Our study centers on the particular Lagrangian $f(T)=T+\alpha{T^n}$, where $|n|\neq 1$ and $\alpha$ is a small unknown constant.
• To do this we treat galactic rotation curves as being composed from two distinct features of galaxies, namely the disk and the bulge.
• This process is carried out for several values of the index $n$.
