In this talk I will present a few avenues to tackle this issue, either using simulation-calibrated priors, a frequentist framework, or a bayesian reparametrization approach. All of these approaches can significantly reduce the projection effects, following different strategies.<br \/>\nSpecifically, I will show the ongoing application of these methods to current DESI DR1 data, and will compare the results among them and with the baseline DESI analysis.<br \/>\nhttps:\/\/indico.in2p3.fr\/event\/35426\/<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Speakers: Marco Bonici (INAF-IASF Milano) 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 [&hellip;]<\/p>\n","protected":false},"author":8,"featured_media":0,"template":"","meta":{"_acf_changed":false,"_tribe_events_status":"","_tribe_events_status_reason":"","footnotes":""},"tags":[],"tribe_events_cat":[],"class_list":["post-9099","tribe_events","type-tribe_events","status-publish","hentry"],"acf":[],"_links":{"self":[{"href":"https:\/\/www.lapth.cnrs.fr\/en\/wp-json\/wp\/v2\/tribe_events\/9099","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.lapth.cnrs.fr\/en\/wp-json\/wp\/v2\/tribe_events"}],"about":[{"href":"https:\/\/www.lapth.cnrs.fr\/en\/wp-json\/wp\/v2\/types\/tribe_events"}],"author":[{"embeddable":true,"href":"https:\/\/www.lapth.cnrs.fr\/en\/wp-json\/wp\/v2\/users\/8"}],"version-history":[{"count":2,"href":"https:\/\/www.lapth.cnrs.fr\/en\/wp-json\/wp\/v2\/tribe_events\/9099\/revisions"}],"predecessor-version":[{"id":10065,"href":"https:\/\/www.lapth.cnrs.fr\/en\/wp-json\/wp\/v2\/tribe_events\/9099\/revisions\/10065"}],"wp:attachment":[{"href":"https:\/\/www.lapth.cnrs.fr\/en\/wp-json\/wp\/v2\/media?parent=9099"}],"wp:term":[{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.lapth.cnrs.fr\/en\/wp-json\/wp\/v2\/tags?post=9099"},{"taxonomy":"tribe_events_cat","embeddable":true,"href":"https:\/\/www.lapth.cnrs.fr\/en\/wp-json\/wp\/v2\/tribe_events_cat?post=9099"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
