Kenneth F Nicholson
TL;DR
This paper critiques existing equations for galaxy rotation speeds, identifies errors, and presents a new set of equations that enable accurate galaxy mass distribution analysis without dark matter or surface light data.
Contribution
It introduces corrected and practical equations for galaxy rotation speeds that improve mass distribution determination without dark matter assumptions.
Findings
Identified errors in standard galaxy rotation equations
Developed a new set of accurate equations
Enables mass distribution analysis without dark matter
Abstract
Shown are the errors and difficulties of the equations used for galaxy rotation speeds in the book "Galactic Dynamics" (Binney and Tremaine). A usable and accurate set of equations is then presented. The new equations allow easy determination of galaxy mass distribution from the rotation profile with no need for dark matter or any knowledge of galaxy surface light.
