8. Measurment of the BAO with Lya auto and cross correlation functions

Mme victoria de sainte agathe (LPNHE)

05/10/2018 10:00

I will present the current status of the Lya group

9. Measuring Large-Scale Inhomogeneities of Metals

Sean Morrison (LAM)

05/10/2018 10:20

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.

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...

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.

7. 1D power spectrum from Lya forest with eBOSS quasars

Solène Chabanier (CEA Saclay)

05/10/2018 11:50

Presentation of the analysis of the 1D power spectrum from the lyman alpha forest with DR14
