Model-independent tests of cosmic gravity.
Gravitation governs the expansion and fate of the universe, and the growth of large-scale structure within it, but has not been tested in detail on these cosmic scales. The observed acceleration of the expansion may provide signs of gravitational laws beyond general relativity (GR). Since the form of any such extension is not clear, from either theory or data, we adopt a model-independent appro...
متن کاملA cosmic speed-trap: a gravity-independent test of cosmic acceleration using baryon acoustic oscillations
We propose a new and highly model-independent test of cosmic acceleration by comparing observations of the baryon acoustic oscillation (BAO) scale at low and intermediate redshifts: we derive a new inequality relating BAO observables at two distinct redshifts, which must be satisfied for any reasonable homogeneous non-accelerating model, but is violated by models similar to cold dark matter, du...
متن کاملTests of chameleon gravity
Theories of modified gravity, where light scalars with non-trivial self-interactions and non-minimal couplings to matter-chameleon and symmetron theories-dynamically suppress deviations from general relativity in the solar system. On other scales, the environmental nature of the screening means that such scalars may be relevant. The highly-nonlinear nature of screening mechanisms means that the...

lishes its sexual identity at the same time that X-chromosome dosage is regulated. However, even in Drosophila, a cell’s sexual identity can be overridden by secreted signals. How should Zhao and colleagues’ results be reconciled with the substantial body of work involving hormone-induced sex reversal in chickens? Seventy-five years of research have definitively demonstrated that oestrogen is n...
