Density weighted angular redshift fluctuations: a new cosmological observable
We propose the use of angular fluctuations in the galaxy redshift field as a new way to extract cosmological information in the Universe. This new probe $\delta z (\hat{\mathbf {n}})$ consists of the statistics of sky maps built by projecting redshifts under a Gaussian window of width σ z centred upon a redshift z obs, and weighted by the galaxy
