Obiettivo We address in this proposal the inverse problem for the reconstruction of the properties of the intergalactic medium based on the measured neutral hydrogen Lyman-α absorption observed in the spectra of high redshift quasars. We suggest the application of ARGO, a Bayesian sampling solver that has been developed by the applicant during his PhD thesis for the reconstruction of the large-scale structure and its properties based on galaxy redshift-surveys. This will permit for the first time to have a self-consistent reconstruction of all the relevant properties of the intergalactic medium. Some further developments are required in order to extent this work to the reconstruction of the intergalactic medium that should be implemented during this training. However, the numerical technology developed by the applicant A novel Krylov-space based inverse scheme included in ARGO allows for efficient reconstruction steps as is required for sampling purposes even in huge dimensional spaces. The cosmological information extracted from this study, such as the cosmological parameters is expected to be qualitatively better than in previous works in this field. This project should have major contributions in the understanding of galaxy and structure formation Parole chiave Natural sciences Physical sciences Technological sciences Programma(i) FP7-PEOPLE - Specific programme "People" implementing the Seventh Framework Programme of the European Community for research, technological development and demonstration activities (2007 to 2013) Argomento(i) PEOPLE-2007-2-1.IEF - Marie Curie Action: "Intra-European Fellowships for Career Development" Invito a presentare proposte FP7-PEOPLE-2007-2-1-IEF Vedi altri progetti per questo bando Meccanismo di finanziamento MC-IEF - Intra-European Fellowships (IEF) Coordinatore SCUOLA NORMALE SUPERIORE Contributo UE € 75 425,98 Indirizzo PIAZZA DEI CAVALIERI 7 56126 Pisa Italia Mostra sulla mappa Regione Centro (IT) Toscana Pisa Tipo di attività Higher or Secondary Education Establishments Contatto amministrativo Beatrice Semzaconi (Dr.) Collegamenti Contatta l’organizzazione Opens in new window Sito web Opens in new window Costo totale Nessun dato Partecipanti (1) Classifica in ordine alfabetico Classifica per Contributo UE Espandi tutto Riduci tutto SCUOLA INTERNAZIONALE SUPERIORE DI STUDI AVANZATI DI TRIESTE Partecipazione conclusa Italia Contributo UE € 77 694,02 Indirizzo VIA BONOMEA 265 34136 Trieste Mostra sulla mappa Regione Nord-Est Friuli-Venezia Giulia Trieste Tipo di attività Higher or Secondary Education Establishments Contatto amministrativo Giuliana Zotta (Prof.) Collegamenti Contatta l’organizzazione Opens in new window Sito web Opens in new window Costo totale Nessun dato
