Cosmo-Astro Seminar | Taming projection effects in EFTofLSS analysis of DESI DR1 and beyond

The analysis of galaxy clustering measurements from surveys like Euclid or DESI is likely to be affected by the so-called projection effects, which causes the 1D marginals of the analysis to not contain the bestfit; this is a serious issue which can potentially harm the cosmological interpretation of these analyses. In this talk I will present a few avenues to tackle this issue, either using simulation-calibrated priors, a frequentist framework, or a reparametrization approach. All of these approaches can significantly reduce the projection effects, following different strategies. Specifically, I will show the application of these methods to current DESI DR1 data, and will compare the results among them and with the baseline DESI analysis, discussing as well the prospects for DESI DR2 and Euclid future analysis.
