Description
The reconstruction technique has been widely used to improve the BAO measurement in spectroscopic survey data. In this work, we explore reconstruction of the BAO signals in photometric data. We generalize the standard Zel’dovich reconstruction technique to study the transverse BAO reconstruction in the presence of photo-z uncertainties. The performance of the BAO reconstruction is checked with N-body simulations. We find that for dense enough sample, the transverse BAO reconstruction can improve the BAO signals in photometric data. The method can be easily adapted for application in survey data.
