Misha Ivanov & I present the first joint full-shape analysis of the galaxy power spectrum and bispectrum using @sdssurveys data. We find sigma8 = 0.72+-0.03, H0 = 68.3+-0.8, S8 = 0.75+-0.04, with the bispectrum improving sigma8 by 13%! <LINK> <LINK> The analysis uses the power spectrum multipoles, the real-space power spectrum extension, the reconstructed power spectrum, and the bispectrum model. For the first time, spectra are measured using *unwindowed* estimators, so the mask doesn't need to be included in the theory! Our LCDM constraints are mostly consistent with Planck, but we find a slightly low S8, matching weak lensing probes. We also get strong constraints on galaxy bias parameters! <LINK> All the data products are publicly available (<LINK>) and the pipeline can be easily reapplied to @desisurvey and @ESA_Euclid data. Coming soon: bispectrum multipoles, neutrino masses, primordial non-Gaussianity...",http://arxiv.org/abs/2112.04515,"We present a full $\Lambda$CDM analysis of the BOSS DR12 dataset, including information from the power spectrum multipoles, the real-space power spectrum, the reconstructed power spectrum and the bispectrum monopole. This is the first analysis to feature a complete treatment of the galaxy bispectrum, including a consistent theoretical model and without large-scale cuts. Unlike previous works, the statistics are measured using window-free estimators: this greatly reduces computational costs by removing the need to window-convolve the theory model. Our pipeline is tested using a suite of high-resolution mocks and shown to be robust and precise, with systematic errors far below the statistical thresholds. Inclusion of the bispectrum yields consistent parameter constraints and shrinks the $\sigma_8$ posterior by $13\%$ to reach $<5\%$ precision; less conservative analysis choices would reduce the error-bars further. Our constraints are broadly consistent with Planck: in particular, we find $H_0 = 69.6^{+1.1}_{-1.3}\,\mathrm{km}\,\mathrm{s}^{-1}\mathrm{Mpc}^{-1}$, $\sigma_8 = 0.692^{+0.035}_{-0.041}$ and $n_s=0.870^{+0.067}_{-0.064}$, including a BBN prior on the baryon density. When $n_s$ is set by Planck, we find $H_0 = 68.31^{+0.83}_{-0.86}\,\mathrm{km}\,\mathrm{s}^{-1}\mathrm{Mpc}^{-1}$ and $\sigma_8 = 0.722^{+0.032}_{-0.036}$. Our $S_8$ posterior, $0.751\pm0.039$, is consistent with weak lensing studies, but lower than Planck. Constraints on the higher-order bias parameters are significantly strengthened from the inclusion of the bispectrum, and we find no evidence for deviation from the dark matter halo bias relations. These results represent the most complete full-shape analysis of BOSS DR12 to-date, and the corresponding spectra will enable a variety of beyond-$\Lambda$CDM analyses, probing phenomena such as the neutrino mass and primordial non-Gaussianity.
