Descrizione del progetto
Un nuovo paradigma di confronto dati-modello della galassia
Il progetto GALSIZE, finanziato dall’UE, intende fondare un nuovo paradigma di confronto dati-modello della galassia. Caratterizzerà inoltre la natura della materia scura e delle materia luminosa nelle galassie, nonché il loro accoppiamento, con l’aiuto di relazioni di scala, tracciatori di massa e simulazioni numeriche. Il progetto espanderà anche le inferenze dei modelli nel regno inesplorato delle galassie di piccola massa. Per fare ciò, il progetto prevede di raccogliere il più grande e completo catalogo di proprietà strutturali e dinamiche delle galassie risolte spazialmente. Il progetto sarà guidato dal Gruppo di Astrofisica della Queens’University (Canada) e dall’Istituto di Astrofisica delle Isole Canarie (Spagna), istituzioni leader a livello mondiale per lo studio delle galassie e della materia oscura.
Obiettivo
I propose the project Galaxy Sizes as Tracers of Dark Matter (GALSIZE) to be supervised by Prof. Courteau at Queen’s University in Kingston (Canada, Third Country for the outgoing phase) and by Prof. Knapen at the Instituto de Astrofísica de Canarias (IAC, Tenerife, Spain, beneficiary institution and host for the incoming phase). The main scientific goals are to (S01) establish a new paradigm of galaxy data-model comparisons, developing a definitive theory of disk formation based on galaxy sizes; (S02) characterize the nature of, and coupling between, dark and luminous matter in galaxies, with the aid of scaling relations, mass tracers, and numerical simulations; and (S03) expand model inferences into the uncharted realm of low-mass galaxies. These objectives will be tackled by assembling the largest and most complete catalogue of spatially resolved structural and dynamical properties (WP2) of galaxies to characterize in a novel way their luminous and dark components (WP3). Queen's University is a world-leading institution for the study of dark matter. The Queen’s Astrophysics Group includes many experts in the observational and numerical characterization of luminous and dark matter in galaxies. The Queen’s Astroparticle group, led by 2015 Physics Nobel Laureate Prof. Art McDonald, is also at the forefront of experimental cold dark matter detections. The return phase institution, the IAC, hosts world experts in both the empirical analysis and numerical modelling of galaxies. It provides access to supercomputers and world-class telescopes (best optical/near-IR observatory in Europe). Through this MSCA-IF-GF, my training in Canada would capitalize upon my past experiences (former MSCA ESR in DAGAL ITN) by coupling photometric and spectroscopic properties of unprecedentedly large sets of galaxies and simulations to constrain in a novel way models of galaxy formation. Dissemination of the knowledge acquired in Canada would greatly complement related European efforts.
