Description
The BOSS Lyα forest survey is obtaining Lyα forest sightlines for over 160,000 QSOs at z>2. While the signal-to-noise and resolution is moderate, I will show that it is possible to obtain information on the IGM temperature-density relation by measuring the flux PDF from the BOSS Lyα forest data. I will discuss new methods for continuum-estimation, noise- and metal-modelling that allow us to take a forward modelling approach to compare simulation spectra with the actual BOSS data. I will conclude with preliminary comparisons between the BOSS measurements and simulated spectra.
