Description
Peak Sirens employs the cross-correlations of galaxies with dark sirens as a diagnostic for the luminosity distance-redshift relation: the amplitude of their angular cross-spectra peaks for redshift bins and distance bins which fall upon the curve $D_L(z)$. I will present the latest constraints with existing data as well as forecasts. I will also discuss the galaxy catalog requirements for accurate estimates of $H_0$, and how forward-simulations of the relationships between galaxies and dark are key to uncover the connections between Peak Sirens and other methods to infer $H_0$ from dark sirens data.
