Abstract

The three-dimensional correlation function offers an effective way to summarize the correlation of the large-scale structure even for imaging galaxy surveys. We have applied the projected three-dimensional correlation function, ζ_p to measure the baryonic acoustic oscillations (BAO) scale on the first-three years Dark Energy Survey data. The sample consists of about 7 million galaxies in the redshift range 0.6< z_p<1.1 over a footprint of 4108 deg². Our theory modeling includes the impact of realistic true redshift distributions beyond Gaussian photo-z approximation. ζ_p is obtained by projecting the three-dimensional correlation to the transverse direction. To increase the signal-to-noise of the measurements, we have considered a Gaussian stacking window function in place of the commonly used top-hat. ζ_p is sensitive to DM(z_eff)/rs, the ratio between the comoving angular diameter distance and the sound horizon. Using the full sample, DM(z_eff)/rs is constrained to be 19.00±0.67 (top-hat) and 19.15±0.58 (Gaussian) at z_eff=0.835. The constraint is weaker than the angular correlation w constraint (18.84±0.50), and we trace this to the fact that the BAO signals are heterogeneous across redshift. While ζ_p responds to the heterogeneous signals by enlarging the error bar, w can still give a tight bound on DM/r_s in this case. When a homogeneous BAO-signal subsample in the range 0.7< z_p<1.0 (z_eff=0.845) is considered, ζ_p yields 19.80±0.67 (top-hat) and 19.84±0.53 (Gaussian). The latter is mildly stronger than the w constraint (19.86±0.55). We find that the ζ_p results are more sensitive to photo-z errors than w because ζ_p keeps the three-dimensional clustering information causing it to be more prone to photo-z noise. The Gaussian window gives more robust results than the top-hat as the former is designed to suppress the low signal modes. ζ_p and the angular statistics such as w have their own pros and cons, and they serve an important crosscheck with each other.
