  2. 9. Measuring Large-Scale Inhomogeneities of Metals
    Sean Morrison (LAM)

    We are measuring the large scale of inhomogeneity of metals, which are expected to be associated with large scale proximity to quasars. These inhomogeneities are currently traced by combining oxygen, helium and hydrogen absorption, but in the future they will refer to directly observed quasar positions.

  3. 4. DLA bias as a function of DLA properties
    Ignasi Pérez-Ràfols (LAM, Marseille)
    05/10/2018 10:40

    I am going to present the latest measurements of the DLA bias. In particular I'll present its evolution with redshift, column density of the DLAs, and the metal strength of the DLAs. The metal strength is defined from an average of equivalent widths of the strongest detectable low-ionization metal lines. These results confirm the physical origin of the relation of bias factors measured from...

  4. 3. The Study of Galaxies in Absorption and their use as a tracer.
    Matthew Pieri (Laboratoire d'Astrophysique de Marseille)
    05/10/2018 11:30

    I will discuss latest results on the properties of galaxies traced by the strong Lyman-alpha forest absorption and, on combining them with Damped Lyman alpha forest absorbers, their use as a BAO tracer.
