How black hole mimickers and Shapiro-free lenses signal effective dark matter
Lirui Yang, Will Barker, Tobias Mistele +1
We report the existence of two exotic compact objects in the leading relativistic model of modified Newtonian dynamics, namely aether-scalar-tensor theory. This model is consistent…
Modified Newtonian Dynamics (MOND)
Benoit Famaey, Amel Durakovic
This chapter presents Modified Newtonian Dynamics (MOND), the proposal that, below a certain acceleration scale , dynamics departs from the Newtonian expectation. In that cont…
A new non-parametric method to infer galaxy cluster masses from weak lensing
Tobias Mistele, Amel Durakovic
We introduce a new, non-parametric method to infer deprojected 3D mass profiles of galaxy clusters from weak gravitational lensing observations. The method assumes spherical…
Buchdahl bound, photon ring, ISCO and radial acceleration in Einstein-æther theory
Yi-Hsiung Hsu, Anthony Lasenby, Will Barker +2
Spherically symmetric Einstein-æther (EÃ) theory with a Maxwell-like kinetic term is revisited. We consider a general choice of the metric and the æther field, finding that:~(i)…
