Description
I will present the current status of the baryon
acoustic oscillations measurement using the flux correlation function
of BOSS Lyman-alpha forests. The BOSS program is now
complete and more than 180 000 forests were measured during 5 years of
operation. We currently have a better understanding of systematic errors in our
measurement, coming both from astrophysics (spurious absorption by metals) and
the data analysis itself (extraction of photons, flux calibration, continuum fitting).
I will overview these improvements and also mention plans for future with the eBOSS survey.
