The lauda, a vibrant expression of popular piety, is the poetic-musical genre that from the second half of the twelfth century marked the birth and the spread of singing in the Italian language. It was based on melodies of varied origins, but mostly functional in orally conveying – through minstrels, lay confraternities and preachers – the dissemination of texts and (not only spiritual) concepts among a largely illiterate population. Despite this ‘volatility’, a good corpus of laude has been preserved in written form for ritual needs, sometimes with musical notation, forming an impressive repository of ‘frozen orality’. While realizing the importance and vastness of this heritage, scholars for over a century have been mainly engaged in alternatively considering it either from a literary or a musical point of view. Therefore, no systematic research has yet to shed light on the specific nature of the phenomenon, its dynamics of creation and transmission and all indicators that make it a reliable mirror of society, culture and mentality in medieval and early Renaissance Italy. The LAUDARE project aims to approach the Italian lauda in its intrinsic intermediality by collecting the whole corpus of texts handed down with music up to the mid 1500s and comprehensively exploring the dynamics of composition and transmission of poems and related tunes according to the mechanisms of orality. An open access database, making searchable the entire corpus, will allow wide-ranging surveys such as the territorial impact of a text and/or its musical setting as well as the diffusion of melodic patterns and text formulas. The results will be collected in a specific volume. Other expected outputs are a handbook, at least ten open access articles, three workshops and two international conferences with proceedings, one of which will have involved related disciplines such as medieval and religious history, linguistics, palaeography, iconography, anthropology, and urban studies.

INITIUM: an Innovative Negative Ion TIme projection chamber for Underground dark Matter searches. INITIUM goal is to boost the advancement of gaseous Time Projection Chamber detectors in the Dark Matter (DM) searches field, one of the most compelling issues of todays fundamental physics. I believe this approach to be superior because of its active neutron/electron discrimination, directional and fiducialization capability down to low energies and versatility in terms of target material. Thanks to recent advances in Micro Pattern Gas Detectors amplification and improved readout techniques, TPCs are nowadays mature detectors to aim at developing a ton-scale experiment. INITIUM focuses on the development and operation of the first 1 m3 Negative Ion TPC with Gas Electron Multipliers amplification and optical readout with CMOS-based cameras and PMTs for directional DM searches at Laboratori Nazionali del Gran Sasso (LNGS). INITIUM will put new significant constraints in a DM WIMP-nucleon scattering parameter space still unexplored to these days, with a remarkable sensitivity down to 10-42-10-43 cm2 for Spin Independent coupling in the 1-10 GeV WIMP mass region. As a by-product, INITIUM will also precisely and simultaneously measure environmental fast and thermal neutron flux at LNGS, supplying crucial information for any present and future experiment in this location. Consequently, I will demonstrate the proof-of-principle and scalability of INITIUM approach towards the development of a ton-scale detector in the context of CYGNUS, an international collaboration (of which I am one of the Spokespersons and PIs) recently gathered together with the aim to establish a Galactic Directional Recoil Observatory, that can test the DM hypothesis beyond the Neutrino Floor and measure the coherent scatter of galactic neutrinos, generating a significant long-term impact on detection techniques for rare events searches.

Experimental astroparticle physics is currently one of the most vibrant and exciting areas of fundamental physics and in the coming decade there is a real potential to experimentally resolve two remaining big puzzles in our understanding of the Universe: the nature of dark matter (DM) and the Baryon Asymmetry of the Universe (BAU, i.e. why there is more matter than antimatter). We currently do not know what is the nature of 95% of the energy density of our Universe. Astronomical observations tell us that at least 23% of the unknown density should behave like matter – as we cannot see it, we call it dark matter. The exact nature of DM (and dark energy) is still unknown and its origin is at present one of the most important questions in physics. Particle physics beyond the Standard Model provides several candidate particles which could be the DM. Out of these, Weakly Interacting Massive Particles (WIMPs) are the best motivated. Discovering them would be a major breakthrough and a sign of physics beyond the Standard Model. The DarkWave consortium aims to make key contributions towards this discovery by: (1) building DarkSide-20k, the next generation experiment searching for dark matter via elastic scattering of dark matter particles in liquid argon (LAr), with sensitivity two orders of magnitude beyond current searches at ~1 TeV/c2 WIMP mass, (2) developing new technologies for ARGO and DarkSide-LM, the ultimate detectors, able to probe the full parameter space where WIMPs can be found. It will also (3) exploit technological synergies with two other key areas in astroparticle physics: long-baseline neutrino oscillation experiments (DUNE) and gravitational wave detection.

The discovery of gravitational waves (GWs) marks the dawn of a new era for astronomy. On 2019 May 21, the gravitational-wave (GW) detectors LIGO and Virgo observed the coalescence of a massive binary black hole: the merger remnant of GW190521 is the first intermediate-mass black hole (IMBH) observed through GWs. This opens new perspectives for the study of IMBHs, bridging the gap between stellar-mass and supermassive black holes. The interpretation of current and future observations requires a theoretical framework capable of modelling both the formation of IMBHs and their co-evolution with the host star clusters. Numerical simulations offer a unique tool to model IMBHs from the seeding phase to their full growth. However, the existing literature misses a thorough study that fully explores the parameter space and captures the complex physics behind IMBHs. Including these aspects represents a fundamental step to bridge stellar dynamics and GW astronomy. The GRACE-BH project aims at building such a bridge providing a solution to one of the challenging questions of modern astrophysics: What are the best conditions favouring the formation of IMBHs in star clusters? To address this open question, I will combine forefront numerical simulations and semi-analytic techniques to probe the parameter space, focusing on the role of stellar multiplicity and primordial mass segregation in star clusters. I will model the complex physics associated with IMBH formation, investigating the impact of dynamical interactions, runaway collisions, pair-instability and relativistic kicks on IMBH formation. The exploitation of these models will enable us to describe the survival and growth of IMBH seeds in different environments, shedding a light on the conditions that favour IMBH formation in star clusters. This will allow us to dissect the demography of GW sources powered by IMBHs and to make predictions for next-generation ground-based and spaceborne GW detectors like LISA.

ACME (the Astrophysics Centre for Multi-messenger studies in Europe) addresses the EC Call to provide wider, simplified, and more efficient access to the best research infrastructures (RI) available to researchers in the astronomy and astroparticle physics communities. ACME is set up to realize an ambitious coordinated European-wide optimization of the accessibility and cohesion between multiple leading RI, offering access to instruments, data and expertise, focused on the new science of multi-messenger astrophysics. ACME will forge a basis for strengthened long-term collaboration between these RI irrespective of location. Collaboration and user training will be specifically aimed at levelling up access opportunities across Europe and beyond. ACME objectives are: - implement the European roadmaps’ recommendations and act as a pathfinder to broaden, improve and align access to the respective RI services and data, and assess and evaluate new models for better coordination and provision of at-scale services - provide harmonized and inclusive trans-national and virtual access to world-class RI - develop centres of expertise providing expert support to enable easier access for more researchers - improve science data products management to facilitate both focused research goals and serendipitous discoveries, implementing FAIR approaches to broaden access - improve interoperable systems for rapid identification of astrophysical candidate events, and alert distribution to the network of RI and scientific consortia to optimize follow-up observations - provide training for a new and broader generation of scientists and engineers - open the astrophysics and astroparticle physics data sets to other disciplines, such as environmental studies or marine biology for the undersea neutrino facilities and increase citizen engagement in scientific research
