BOSS Detects Baryon Acoustic Oscillations in the Lyman-alpha Forest at z of 2.3.

SDSS-III astronomers announce today the first detection of BAO in the Lyman-alpha forest 11 billion years ago. The paper has been submitted to Astronomy & Astrophysics and is available on arXiv:

“Baryon Acoustic Oscillations in the Ly-α forest of BOSS quasars”
N. Busca et al.

The new BOSS Lyman-alpha measurement of H(z)/(1+z) is illustrated by the red dot.


The Lyman-alpha forest is detected through the imprint of hydrogen cloud absorpt
ion lines on the light from background quasars.

    much better. Thank u ,Arlie
