We present the first application to real data from the BOSS DR12 dataset of the Extractor procedure (Noda et al., 2017, Nishimichi et al., 2018) to determine the acoustic scale imprinted on Baryonic Acoustic Oscillations (BAO). We show that, being largely insensitive to the broadband shape of the Power Spectrum, this procedure requires a lower number of nuisance parameters than those used by the BOSS collaboration, For non-reconstructed data our analysis improves the accuracy on the acoustic scale by about 20%, while for reconstructed ones we get essentially the same level of accuracy as the BOSS analysis.

Abstract
We present the first application to real data from the BOSS DR12 dataset of the Extractor procedure (Noda et al., 2017, Nishimichi et al., 2018) to determine the acoustic scale imprinted on Baryonic Acoustic Oscillations (BAO). We show that, being largely insensitive to the broadband shape of the Power Spectrum, this procedure requires a lower number of nuisance parameters than those used by the BOSS collaboration, For non-reconstructed data our analysis improves the accuracy on the acoustic scale by about 20%, while for reconstructed ones we get essentially the same level of accuracy as the BOSS analysis.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
