    How well does galaxy clustering constrain cosmology?
    On the LCDM cosmology, dark matter collapses into virialised objects called haloes. The abundance and distribution of these haloes are a direct consequence of...

    Measuring Dark Energy with Massive Redshift Surveys
    The Baryon Oscillation Spectroscopic Survey (BOSS) is a Stage III dark energy experiment on the Sloan Telescope. For the five years from 2009-2014, we are...

    Nonextensive scalar field theories and dark energy models
    Current astronomical measurements indicate that approximately 73% of the universe is made up of dark energy. Stochastically quantized self-interacting scalar...

    Planck 2015 results. XIV. Dark energy and modified gravity
    We study the implications of Planck data for models of dark energy (DE) and modified gravity (MG) beyond the standard cosmological constant scenario. We start...
