Virial masses of galaxy clusters in the post-Newtonian limit
Mahmood Roshan
TL;DR
This paper uses the PPN virial theorem to estimate galaxy cluster masses and demonstrates that post-Newtonian corrections cannot resolve the mass discrepancy problem.
Contribution
It applies the parametrized post-Newtonian virial theorem to galaxy clusters and shows the limitations of post-Newtonian corrections in explaining mass discrepancies.
Findings
Post-Newtonian corrections are insufficient to explain galaxy cluster mass discrepancies.
Virial mass estimates using PPN are consistent with Newtonian estimates.
Post-Newtonian effects do not resolve the missing mass problem.
Abstract
We estimate virial masses of galaxy clusters using the parametrized post-Newtonian (PPN) virial theorem. Also, we show explicitly that post-Newtonian corrections can not address the mass discrepancy in the galaxy clusters.
