# Large–scale structure and matter in the Universe

@article{Peacock2003LargescaleSA, title={Large–scale structure and matter in the Universe}, author={John A Peacock}, journal={Philosophical Transactions of the Royal Society of London. Series A: Mathematical, Physical and Engineering Sciences}, year={2003}, volume={361}, pages={2479 - 2495} }

This paper summarizes the physical mechanisms that encode the type and quantity of cosmological matter in the properties of large-scale structure, and reviews the application of such tests to current datasets. The key lengths of the horizon size at matter-radiation equality and at last scattering determine the total matter density and its ratio to the relativistic density; acoustic oscillations can diagnose whether the matter is collisionless, and small-scale structure or its absence can limit…

We investigate static configurations of a vacuumless scalar field as ‘hair’ on a black hole. The vacuumless field has run-away behaviour, meaning the scalar potential vanishes only at infinite field…
