High-Performance Visualization for Astronomy and Cosmology: Refactoring and Parallelization of VisIVO Server for Exascale Systems [Visualizzazione ad Alte Prestazioni per l’Astronomia e la Cosmologia: Refactoring e Parallelizzazione di VisIVO Server per Sistemi Exascale]
… volumi di dati nei campi dell’astronomia e della cosmologia pone sfide significative per la visualizzazione e l’analisi dei dati. Questa tesi affronta tali sfide evolvendo VisIVO Server, una suite software scientifica per la visualizzazione di dati astrofisici multidimensionali, con l’obiettivo di …

O belo sensível na Filosofia da natureza de Santo Agostinho
… investigar a fundamentação da beleza sensível na cosmologia de Santo Agostinho, que emerge da sintetização das influências neoplatônica-plotiniana e escriturística-cristã em seu contínuo debate com os maniqueus, detectando os principais problemas levantados pelos discípulos de Mani, os quais …

Mondo, libertà, finitezza: Eugen Fink e la questione meontica dell'origine
… e dell’Heraklit-Seminar, mostrando come la cosmologia finkiana, lungi dall’essere una mera integrazione dell’ontologia di Heidegger, implichi una diversa concezione dell’essere, realizzando una vera e propria “rivoluzione della comprensione ontologica”, che sfocia in una differente …

L'APPARATO DEI PMT DI ICARUS E IL SUO SISTEMA DI "SLOW CONTROL".
… Nucleare, Fisica delle Particelle, Astronomia e Cosmologia sono innegabili. I neutrini sono presenti ovunque nell'Universo e sono denominati messaggeri misteriosi della natura. Nel 1930, Pauli propose uno schema in cui il decadimento beta possa essere un decadimento a tre corpi, in cui una …

Homogeneidades espacial e observacional da distribuição de galáxias
In this work we propose a second way of analysing the homogeneity of the matter distribution in the Universe, called here as observational homogeneity (OH), and which is carried out along the past light cone null type hypersurface. The usual type of homogeneity is given by the Cosmological …

Procedure di modellizzazione rapide per la caratterizzazione di Supernovae Core Collapse e di transienti similari
… in diversi settori della fisica moderna, dalla cosmologia all'astronomia multi-messaggera, nell'ultimo decennio un gran numero di supernovae (SN) è stato classificato e seguito da estesi programmi di monitoraggio di transitori (ad esempio ePESSTO+, ZTF). Questo numero aumenterà rapidamente con …

Perturbações das equações de Einstein-Boltzmann e suas aplicações à radiação cósmica de fundo
Study aimed at understanding the basics of the new and growing topic of cosmic microwave background (CMB) physics. We present the fundamental concepts, principles and results related with this problem. Since the relevant equations are essentially the Einstein-Boltzmann perturbed equations, a great …

On Inflationary cosmological models
The most common mechanisms leading to in ation are based on models of gravity minimally coupled to a scalar field rolling on a suitable potential V. We discuss such a model defined by the action I = ∫√-g p [R -2 (φ)2 )] d4x, in order to find exact general isotropic and homogeneous cosmological …

ON METAL ABUNDANCE AND ENTROPY OF THE ICM: THE TWIN TRACERS OF BARYON EVOLUTION IN GALAXY CLUSTERS
Galaxy clusters are ideal systems for both cosmological and astrophysical studies, and their physical properties are determined by an interplay between baryonic and non-baryonic components. In particular, the main baryonic component of a cluster is the intracluster medium (ICM), the hot and diffuse …

STRONG GRAVITATIONAL LENSING MODELLING OF GALAXY CLUSTERS IN THE ERA OF BIG DATA
Current observational facilities and surveys are revolutionizing the field of strong lensing (SL) by galaxy clusters. Remarkably, the Euclid Survey will cover approximately 15,000 square degrees of the sky, detecting SL features in thousands of massive clusters. Complementarily, the James Webb …

ASSESSING THE ROLE OF EXTERNAL PHOTOEVAPORATION OF PROTOPLANETARY DISCS IN NEARBY STAR-FORMING REGIONS
Characterising the physical processes driving protoplanetary disc evolution and the connection to the star-forming environment is essential to understanding planet formation and diversity. Most stars (and their discs) in the Galaxy form in massive clusters where the intense UV radiation emitted by …

FOREGROUND CONTROL AND CHARACTERIZATION IN COSMIC MICROWAVE BACKGROUND EXPERIMENTS
The CMB is a relic radiation from the early stage of the Universe, when radiation was initially coupled with the primordial plasma, currently detected as a blackbody spectrum in the microwave range. Measuring its intensity anisotropies and the so-called E-modes polarization pattern have proven to …

FROM DATA PRODUCTION TO SEARCH FOR GALACTIC COSMICRAY SOURCES WITH THE PIERRE AUGER OBSERVATORY
Astroparticle physics, at the crossroads of astrophysics and particle physics, investigates ultra-high-energy cosmic rays (UHECRs), the most energetic particles known in the Universe. Despite decades of research, their origins remain elusive. These particles are detected through extensive air …
