Possible detection of Baryon Acoustic Oscillations imprinted in the HI sources from the FASHI catalog

Motivated by curiosity as to whether the observed Universe at low redshifts is well described by the concordance cosmological model, we investigate the large scale angular clustering of extragalactic neutral hydrogen HI sources in the local Universe. Using the second data release of the FAST All Sky HI Survey (FASHI),...
