In this work, we analyze the SDSS-DR16 quasar catalog to search for the 2D BAO signal in the unexplored redshift interval $1.5 \\leq z \\leq 2.0$. Performing a fine tomographic analysis in 50 thin disjoint redshift shells ($\\Delta z = 0.01$), to suppress line-of-sight projection smearing, and incorporating a full analytical covariance matrix, we detect the acoustic peak in two uncorrelated redshift shells: $\\theta_{\\rm ","authors_text":"Armando Bernui, Felipe Avila, Miguel A.
