Objective 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 Keywords Natural sciences Physical sciences Technological sciences Programme(s) FP7-PEOPLE - Specific programme "People" implementing the Seventh Framework Programme of the European Community for research, technological development and demonstration activities (2007 to 2013) Topic(s) PEOPLE-2007-2-1.IEF - Marie Curie Action: "Intra-European Fellowships for Career Development" Call for proposal FP7-PEOPLE-2007-2-1-IEF See other projects for this call Funding Scheme MC-IEF - Intra-European Fellowships (IEF) Coordinator SCUOLA NORMALE SUPERIORE EU contribution € 75 425,98 Address PIAZZA DEI CAVALIERI 7 56126 Pisa Italy See on map Region Centro (IT) Toscana Pisa Activity type Higher or Secondary Education Establishments Administrative Contact Beatrice Semzaconi (Dr.) Links Contact the organisation Opens in new window Website Opens in new window Total cost No data Participants (1) Sort alphabetically Sort by EU Contribution Expand all Collapse all SCUOLA INTERNAZIONALE SUPERIORE DI STUDI AVANZATI DI TRIESTE Participation ended Italy EU contribution € 77 694,02 Address VIA BONOMEA 265 34136 Trieste See on map Region Nord-Est Friuli-Venezia Giulia Trieste Activity type Higher or Secondary Education Establishments Administrative Contact Giuliana Zotta (Prof.) Links Contact the organisation Opens in new window Website Opens in new window Total cost No data
