Synchronize your chrono-brane: testing a variable brane tension model with strong gravitational lensing
Published 2024-01-01“…In this paper we present a strong lensing joint analysis using a compilation of early-type galaxies acting as a lenses, united with the power of the well studied strong lensing galaxy cluster Abell 1689. We use the strong lensing constraints to investigate a brane model with variable brane tension as a function of the redshift. …”
