Scaling the smoothness of the IGM
R. N. Guimarães, P. Petitjean, E. Rollinde +3
We use, for the first time, the Detrend Fluctuation Analysis (DFA) to study the correlation properties of the transmitted flux fluctuations, in the Lyman- (Ly) Forest along t…
Chemical constraints on the contribution of Population III stars to cosmic reionization
Girish Kulkarni, Joseph F. Hennawi, Emmanuel Rollinde +1
Recent studies have highlighted that galaxies at z = 6-8 fall short of producing enough ionizing photons to reionize the IGM, and suggest that Population III stars could resolve th…
The one-dimensional Ly-alpha forest power spectrum from BOSS
Nathalie Palanque-Delabrouille, Christophe Yèche, Arnaud Borde +33
We have developed two independent methods to measure the one-dimensional power spectrum of the transmitted flux in the Lyman- forest. The first method is based on a Fourier tran…
The large-scale Quasar-Lyman α Forest Cross-Correlation from BOSS
Andreu Font-Ribera, Eduard Arnau, Jordi Miralda-Escudé +12
We measure the large-scale cross-correlation of quasars with the Lyman α forest absorption in redshift space, using ~ 60000 quasar spectra from Data Release 9 (DR9) of the Baryon O…
Chemical enrichment of Damped Lyman Alpha systems as a direct constraint on Population III star formation
Girish Kulkarni, Emmanuel Rollinde, Joseph F. Hennawi +1
Damped Ly-alpha absorbers (DLAs) can be used to measure gas-phase metallicities at large cosmological lookback times with high precision. Relative abundances can still be measured…
