A simple model for explaining Galaxy Rotation Curves
Aneta Wojnar, Ciprian A. Sporea, Andrzej Borowiec
TL;DR
This paper introduces a simple mathematical model for galaxy rotation curves and tests its accuracy against observational data, comparing it with the Modified Newtonian Dynamics (MOND) theory.
Contribution
The paper proposes a new simple expression for galaxy rotation velocities and evaluates its performance against real galaxy data and MOND.
Findings
The model fits the observational data well.
It performs comparably or better than MOND.
The approach offers a simpler alternative for explaining galaxy rotation curves.
Abstract
A new simple expression for the circular velocity of spiral galaxies is proposed and tested against HI Nearby Galaxy Survey (THINGS) data set. Its accuracy is compared with the one coming from MOND.
