A methodological workflow for the identification of earthquake sources from macroseismic data

Macroseismic intensity data are a fundamental source of information for characterising historical earthquakes. This study presents a methodology to constrain the sources of large earthquakes through the analysis and modelling of macroseismic intensity data. The proposed workflow...

Construction and characterisation of the DarkSide-20k veto silicon photo-multiplier tiles

Abstract Silicon photo-multipliers (SiPMs) are state-of-the-art sensors capable of detecting a single photoelectron under cryogenic conditions, with potentially lower radioactivity than widely used photomultiplier tubes. The DarkSide-20k experiment, designed to perform direct dar...

A physics-informed neural network approach to diffusion and auto-oxidation in Fricke gel dosimeters

Precise dose quantification is critical for advanced radiation-based medical applications, particularly in emerging high dose-rate and mini-beam therapies. Fricke gels (FGs) are promising tissue-equivalent dosimeters based on the radiation-induced oxidation of \(Fe^{2+}\) to \(Fe...

Dust Substructures and Line Perturbations driven by a Forming Planet in J16120

Abstract Hints of planet formation have been independently reported within the gap of the disc around 2MASS J16120668-301027 from millimetre continuum, infrared, and Hα observations. In this work, we present new evidence for ongoing planet formation based on Atacama Large Millime...

Mapping the nuclear environments of extreme coronal line emitting galaxies

Abstract Extreme coronal line emitters (ECLEs) are a rare class of galactic nuclei exhibiting unusually strong high-ionisation forbidden emission lines, and several ECLEs have been linked to tidal disruption events (TDEs). In this work, we compile and analyse optical spectra of 3...

Identification of a nanosecond isomer of $$^{164}$$Tb

Abstract This letter reports on the identification of a new isomeric state of $$^{164}$$ 164 Tb ( $$Z=65$$ Z = 65 , $$N=99$$ N = 99 ), which was measured with the DESPEC setup at the GSI Helmholtzzentrum für Schwerionenforschung GmbH following the first relativistic fragmentation...

Shape coexistence in 94Zr from a model-independent analysis

Low-lying states of 94Zr were investigated via low-energy multi-step Coulomb excitation. From the measured γ-ray yields, 16 reduced E2 transition probabilities between low-spin states were determined, together with the spectroscopic quadrupole moments of the 2+1,2 states. Based o...

Thermodynamic formulation of Cotton gravity in the Codazzi parametrization

Abstract We develop a thermodynamic formulation of Cotton gravity in the Codazzi parametrization, providing a general framework in which the gravitational dynamics can be interpreted in terms of horizon thermodynamics. As paradigmatic examples, we apply the formalism to Friedmann...

Quantum estimation theory limits in neutrino oscillation experiments

A bstract Measurements of the Pontecorvo-Maki-Nakagawa-Sakata (PMNS) neutrino mixing parameters have entered a precision era, enabling increasingly stringent tests of neutrino oscillations. Within the framework of quantum estimation theory, we investigate whether flavor measureme...

Neutron elastic scattering at $$\varvec{30.8}$$ MeV on $$\varvec{^{\text {nat}}\textrm{Ce}}$$

Abstract Elastic scattering of fast neutrons at an incident energy of 30.8 MeV on a natural cerium target was measured during an experiment conducted at the Neutrons For Science facility at GANIL-SPIRAL2. This is the first measurement on cerium using incident neutron energy above...
