Descrizione del progetto
Gli algoritmi di analisi dei dati delle onde gravitazionali potrebbero portare a una serie di nuove scoperte
Il rilevamento del punto di riferimento delle onde gravitazionali emesse dalla fusione di sistemi binari di buchi neri e stelle di neutroni ha inaugurato una nuova era nella fisica, offrendo l’opportunità di sfidare l’attuale comprensione della materia oscura e dell’energia oscura e verificare se la relatività generale sia ancora valida in regime di campo forte. Risulta tuttavia necessario sviluppare nuovi algoritmi di analisi dei dati per ottenere risultati significativi dalla serie di dati forniti da esperimenti con rivelatori di nuova generazione. Inoltre, i modelli teorici di nuova concezione delle sorgenti di onde gravitazionali non dovrebbero basarsi su teorie standard per sondare la fisica fondamentale. Il progetto GRU, finanziato dall’UE, si propone di creare collaborazioni scientifiche nel campo tramite distaccamenti presso istituzioni in Canada, Giappone e Stati Uniti. Il progetto organizzerà anche conferenze internazionali e workshop per promuoverne la conoscenza.
Obiettivo
Gravitational Universe: Challenges and Opportunities
The landmark detection of gravitational waves (GWs) emitted by merging black-hole and neutron-star binaries has opened a new era in physics, giving us access to the strong-field regime of the gravitational interaction. The wealth of data coming from current and future GW detectors (such as 3G, LISA, PTA) will provide an opportunity to challenge current paradigms, exploring fundamental physics from an entirely new perspective, and eventually finding new physics. In this new observational window, we could learn that general relativity is not adequate to describe the strong-field regime of gravity; new fundamental fields beyond the standard model, or new kinds of compact objects, could challenge current understanding of dark matter and dark energy.
In order to reach these results, the impressive experimental effort put in place will not be sufficient if not accompanied by a similar effort by the theoretical and the data-analysis communities. Severe theoretical and conceptual problems need to be overcame before the new generation of detectors is operating. On one hand, we need to develop new data-analysis algorithms, to extract meaningful results from the impressive amount of data which will be delivered. On the other hand, we need to develop theoretical models of GW sources which do not assume the standard theories and paradigms which we want to test, in order to perform non-biased tests and to use observational results to address fundamental problems. It is of utmost importance that scientists with different expertise and addressing different challenges exchange their views and learn from each other’s problems. The proposed studies can be loosely classified into four groups with considerable overlap: i) Perturbation techniques in general relativity and beyond ii) Non-linear simulations of binary compact objects beyond general relativity iii) GWs from the dark universe iv) Data analysis for GW experiments
