Within the gauge-theoretic approach of gravity, the gauging of an enlarged symmetry of the tangent space in four dimensions allows gravity to be unified with internal interactions. We study the unification of the conformal and noncommutative (fuzzy) gravities with internal interactions based on the $SO(10)$ GUT..

First order phase transitions (FOPT) in the early Universe can be powerful emitters of both relativistic and heavy particles, upon the collision of ultra-relativistic bubble shells. If the particles coupling to the bubble wall have CP-violating interactions, the same collision process can also create a local lepton or baryon charge. [...]

Interpreting the spectral energy distributions (SEDs) of astrophysical objects with physically motivated models is computationally expensive. These models require solving coupled differential equations in high-dimensional parameter spaces, making traditional fitting techniques such as Markov Chain Monte Carlo or nested sampling prohibitive. [...]

Vacuum fluctuations give rise to effective nonlinear interactions between electromagnetic fields. These generically modify the characteristics of light traversing a strong-field region. [...]

This deliverable presents an overview of EOSC-related activities and projects that could be taken into account for the design and implementation of Competence Centres (CCs), positioned as key instruments to support data-intensive, FAIR-compliant, and interdisciplinary research within the European Open Science Cloud (EOSC). It synthesises existing practices, conceptual frameworks, and policy recommendations drawn from ongoing and past projects. [...]

Context. Type Ia supernova (SN Ia) cosmology studies will soon be dominated by systematic, uncertainties, rather than statistical ones [...]

Monolithic Active Pixel Sensors (MAPS) are candidates to serve as vertex and tracking detectors in the future lepton colliders. This is due to the many advantages they provide compared to hybrid sensors, such as a reduced material budget and lower power consumption. [...]

The quest to understand the chemical processes that govern natural phenomena hasbeen a central theme in scientific research throughout the history of humanity. Fromthe large scales studied in astronomy and atmospheric sciences to the intrincate systemsin biochemistry, all such processes ultimately trace back to the dynamics of molecules atatomic and subatomic levels. [...]

Electron beam (EB) modification was carried out on the polylactide (PLA) fibers at the temperature both below and above the glass transition temperature (Tg) under nitrogen atmosphere. The irradiation at elevated temperature was performed by using a novel fiber stretching frame setup to protect fibers from shrinking, in which a permanent constant tension was loaded along fiber bundles to maintain their straightness throughout the irradiation. [...]

This study investigates a cost-effective, cobalt-free Al$_{0.5}$CrNi$_{1.5}$Fe$_2$ multi-principal element alloy, based on the most studied AlCoCrFeNi alloy system. The alloy underwent thermal mechanical treatment to induce partial recrystallization, resulting in a multi-phase, multi-scale heterogeneous microstructure. [...]
