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>","excerpt":"","slug":"marco-bonici","image":false,"all_day":false,"start_date":"2025-04-03 09:00:00","start_date_details":{"year":"2025","month":"04","day":"03","hour":"09","minutes":"00","seconds":"00"},"end_date":"2025-04-03 10:00:00","end_date_details":{"year":"2025","month":"04","day":"03","hour":"10","minutes":"00","seconds":"00"},"utc_start_date":"2025-04-03 09:00:00","utc_start_date_details":{"year":"2025","month":"04","day":"03","hour":"09","minutes":"00","seconds":"00"},"utc_end_date":"2025-04-03 10:00:00","utc_end_date_details":{"year":"2025","month":"04","day":"03","hour":"10","minutes":"00","seconds":"00"},"timezone":"UTC","timezone_abbr":"UTC","cost":"","cost_details":{"currency_symbol":"","currency_code":"","currency_position":"","values":[]},"website":"https:\/\/indico.in2p3.fr\/event\/35426\/","show_map":false,"show_map_link":false,"hide_from_listings":false,"sticky":false,"featured":false,"categories":[],"tags":[],"venue":{"id":8295,"author":"3","status":"publish","date":"2024-03-26 14:33:06","date_utc":"2024-03-26 13:33:06","modified":"2026-03-19 06:38:07","modified_utc":"2026-03-19 05:38:07","url":"https:\/\/www.lapth.cnrs.fr\/venue\/auditorium-vivargent-lapth\/","venue":"Auditorium Vivargent (LAPTh)","slug":"auditorium-vivargent-lapth","json_ld":{"@type":"Place","name":"Auditorium Vivargent (LAPTh)","description":"","url":"","address":{"@type":"PostalAddress"},"telephone":"","sameAs":""},"show_map":true,"show_map_link":true,"global_id":"www.lapth.cnrs.fr\/en\/?id=8295","global_id_lineage":["www.lapth.cnrs.fr\/en\/?id=8295"]},"organizer":[],"custom_fields":[],"json_ld":{"@context":"http:\/\/schema.org","@type":"Event","name":"Taming projection effects in EFT of LSS analysis of DESI","description":"&lt;p&gt;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;]&lt;\/p&gt;\\n","url":"https:\/\/www.lapth.cnrs.fr\/en\/event\/marco-bonici\/","eventAttendanceMode":"https:\/\/schema.org\/OfflineEventAttendanceMode","eventStatus":"https:\/\/schema.org\/EventScheduled","startDate":"2025-04-03T09:00:00+00:00","endDate":"2025-04-03T10:00:00+00:00","location":{"@type":"Place","name":"Auditorium Vivargent (LAPTh)","description":"","url":"","address":{"@type":"PostalAddress"},"telephone":"","sameAs":""},"performer":"Organization"},"event_bgcolor":"","event_text_color":""}
