# On the theory and applications of modern cosmography

@article{Dunsby2015OnTT, title={On the theory and applications of modern cosmography}, author={Peter Dunsby and Orlando Luongo}, journal={arXiv: General Relativity and Quantum Cosmology}, year={2015} }

Cosmography represents an important branch of cosmology which aims to describe the universe without the need of postulating \emph{a priori} any particular cosmological model. All quantities of interest are expanded as a Taylor series around here and now, providing in principle, a way of directly matching with cosmological data. In this way, cosmography can be regarded a model-independent technique, able to fix cosmic bounds, although several issues limit its use in various model reconstructions…
