Abstract
Traditional large-scale structure surveys estimate the power spectra from galaxy surveys where
distances are estimated based on the observed redshift. But not all tracers of dark matter, such as
supernovae Type Ia and gravitational wave merger events, have a measured redshift; instead, they
provide an observed luminosity distance. Therefore the natural estimator would be the observed
number counts in luminosity distance space. In this talk, we would review the full calculation of
clustering in luminosity distance space including all light-cone effects, and establish the differences
with redshift space. We will also present models for the biases that affect the observed angular power
spectrum. Additionally we will discuss the implication of cosmological constraints can have in the
properties of BH population responsible for GW events.
