Detection of baryon acoustic oscillation features in the large-scale three-point correlation function of SDSS BOSS DR12 CMASS galaxies

Abstract: We present the large-scale 3-point correlation function (3PCF) of the SDSS DR12 CMASS sample of 777, 202 Luminous Red Galaxies, the largest-ever sample used for a 3PCF or bispectrum measurement. We make the first high-significance (4.5σ) detection of Baryon Acoustic Oscillations (BAO) in the 3PCF. Using these acoustic features in the 3PCF as a standard ruler, we measure the distance to z = 0.57 to 1.7% precision (statistical plus systematic). We find D V = 2024±29 Mpc (stat)±20 Mpc (sys) for our fiducial cosmo… Show more

“…The BAO has also been detected in the higher order statistics of the 3-point correlation function (Slepian et al 2017) and bispectrum (Pearson & Samushia 2018) for the BOSS CMASS sample. The BAO feature has been measured using voids as the clustering tracer (Kitaura et al 2016a;Liang et al 2016), also in BOSS.…”

“…The formalism used to calculate Eq. 2 using fast Fourier transforms (FFTs) is described in Hand et al (2017b), and builds upon the ideas of Bianchi et al (2015); Scoccimarro (2015) and Slepian & Eisenstein (2015).…”

“…These characteristics make LRGs particularly interesting to study the physics of the baryon cycle because they extend the mass scale to >L* (the COS-Halos survey is ∼L*), and their passivity ensures we are characterizing the CGM around galaxies that are at the end of their star-forming life cycle. Given their importance for cosmological studies (e.g., Eisenstein et al 2005;Xu et al 2013;Slepian et al 2017), there are large samples of LRGs with both SDSS photometry and spectroscopy (Dawson et al 2013(Dawson et al , 2016Prakash et al 2016;Albareti et al 2017). Due to these SDSS surveys, the general characteristics of LRGs are well-understood.…”

“…On larger scales, observations, simulations, and perturbation theory suggests that galaxies do not strictly show a constant Q but exhibit scale and shape dependence (Jing & Börner 1998;Scoccimarro et al 1998;Takada & Jain 2003;McBride et al 2011;Hoffmann et al 2018). The BAO feature has been detected in the 3PCF measurements of BOSS galaxies (Slepian et al 2017), while other studies focus on the galaxy bispectrum (e.g., Tellarini et al 2016;Desjacques et al 2018;Gualdi et al 2019).…”
