    Chronos: A NIR spectroscopic galaxy survey to probe the most fundamental stages of galaxy evolution

    We propose a dedicated, ultra-deep spectroscopic survey in the near infrared (NIR), that will target a mass-limited sample of galaxies during two of the most...

    Euclid: Constraining dark energy coupled to electromagnetism using astrophysical and laboratory data

    In physically realistic, scalar-field-based dynamical dark energy models (including, e.g., quintessence), one naturally expects the scalar field to couple to...
