  "abstract": "We investigate cosmic anisotropy within the updated Pantheon+ sample using both the dipole fitting (DF) and hemisphere comparison (HC) methods. With the DF method, the dipole signal within the full sample is statistically weak. However, the low- z subsample yields a dipole signal of $$A_{\\textrm{D}} = 0.952^{+0.454}_{-0.403} \\times 10^{-3}$$ A D = 0 . 952 - 0.403 + 0.454 × 10 - 3 at $$\\sim 2\\sigma $$ ∼ 2 σ significance, pointing towards $$(l,b) = (149.77^\\circ , -12.20^\\circ )$$ ( l , b ) = ( 149 . 77 ∘ , - 12 . 20 ∘ ) . This signal is predominantly driven by a combined subset of surveys 5, 56, 63, and 150, which is characterized by an amplitude of $$A_{\\textrm{D}} = 1.730_{-0.715}^{+0.554} \\times 10^{-3}$$ A D = 1 . 730 - 0.715 + 0.554 × 10 - 3 towards $$(l,b) = (153.05^\\circ , -1.25^\\circ )$$ ( l , b ) = ( 153 . 05 ∘ , - 1 . 25 ∘ ) . For the HC method, the full sample yields a maximum anisotropy level of $$\\textrm{AL}_{\\textrm{max}} = 0.289 \\pm 0.052$$ AL max = 0.289 ± 0.052 oriented towards $$(l,b) = (127.97^\\circ , 17.90^\\circ )$$ ( l , b ) = ( 127 . 97 ∘ , 17 . 90 ∘ ) with a $$1.56\\sigma $$ 1.56 σ significance. This preferred direction is primarily determined by the highly inhomogeneous SNLS subsample, whereas the low- z and high- z subsamples act to suppress the anisotropy level along this axis. These subsample-dependent results suggest that the apparent anisotropy arises from local structures or the inhomogeneous distribution of the datasets rather than an intrinsic cosmic anisotropy.",
