TL;DR
This paper investigates how noncommutative corrections to gravity are amplified by electromagnetic fields, using pulsar measurements to set bounds on noncommutative gravity parameters.
Contribution
It introduces a method to constrain noncommutative gravity effects through astrophysical observations of neutron stars with strong magnetic fields.
Findings

Bounds on noncommutative gravity parameters are derived from pulsar redshift data.
Neutron stars are effective laboratories for testing noncommutative gravity theories.
Abstract
Noncommutative corrections to the metric tensor can be significantly enhanced by the presence of electromagnetic fields. Neutron stars, with their large magnetic fields, are possible candidates to search for such effects. We use precision measurements of the gravitational redshift from pulsars to put bounds on the parameters of noncommutative gravity.
