Mapping the most massive overdensity through hydrogen (mammoth). I. Methodology
Modern cosmology predicts that a galaxy overdensity (e.g., protocluster) will be associated with a large intergalactic medium gas reservoir, which can be traced by Lyα forest absorption. We have undertaken a systematic study of the relation between Coherently Strong intergalactic Lyα Absorption systems (CoSLAs), which have the highest optical depth (τ) in the τ distribution, and mass overdensities on the scales of ~10–20 h⁻¹ comoving Mpc. On such large scales, our cosmological simulations show...[Show more]
