PowerFull: fast and accurate computation of the relativistic angular galaxy power spectrum including local primordial non-Gaussianity

Current and forthcoming wide-field galaxy surveys, such as SPHEREx and Euclid, provide a unique opportunity to probe the ultra-large scales of structure formation, where primordial non-Gaussianity, often parameterized by $f_\text{NL}$, is expected to leave its most detectable imprint. At the same time, these surveys in...
