abstract

We present a formalism for analysing redshift distortions based on a spherical harmonic expansion of the density field. We use a maximum likelihood estimator for the combination of density and bias parameters, $\Omega^0.6/b$. We test the method with $N$-body simulations and apply it to the 1.2 Jy IRAS redshift survey.

  1. Optimal and exact wide-angle power spectrum estimation

    astro-ph.CO 2026-07 accept novelty 7.0 of 10

    For finite-rank signals the optimal wide-angle estimator is the two-ℓ Yamamoto form, whose exact window is a finite FFT-computable sum that improves ultra-large-scale SNR by O(1).

  2. The observer power spectrum for lightcone statistics, integrated relativistic observables and wide angle effects

    astro-ph.CO 2026-05 unverdicted novelty 6.0 of 10

    Introduces the observer power spectrum as a diagonal Fourier-space statistic for lightcone observables by transforming over observer positions rather than sources.

  3. A unified harmonic framework for dark siren cosmology

    astro-ph.CO 2026-03 unverdicted novelty 6.0 of 10

    The GW-galaxy cross-correlation method, unified with spectral sirens in a harmonic framework, can measure H0 to 1% and Omega_m to 5% precision with 2 years of data from next-generation detectors like Einstein Telescop...
