A Fisher forecast shows the galaxy density-intrinsic alignment cross-spectrum can provide up to half the constraining power of galaxy clustering for a dipolar primordial asymmetry, with negligible degradation from bias marginalization.

Probing dipolar power asymmetry with galaxy clustering and intrinsic alignments
A Fisher forecast shows the galaxy density-intrinsic alignment cross-spectrum can provide up to half the constraining power of galaxy clustering for a dipolar primordial asymmetry, with negligible degradation from bias marginalization.
