Breaking the $f_{\text{NL}}$--$b_{\ddot{I}}•$ degeneracy with the time evolution of tracer number counts

Caio B. de S. Nascimento, Neal Dalal

Constraining local primordial non-Gaussianity through scale-dependent bias requires an accurate determination of the PNG bias parameter $b_{\ddot{I}}•$, which is completely degenerate with…
