Star formation across the w3 complex
(IOP Publishing Ltd., 2015-09)
We present a multi-wavelength analysis of the history of star formation in the W3 complex. Using deep, near-infrared ground-based images combined with images obtained with Spitzer and Chandra observatories, we identified ...

Fluctuating hydrodynamics and mesoscopic effects of spatial correlations in dissipative systems with conserved momentum
(IOP Publishing Ltd., 2015)
We introduce a model described in terms of a scalar velocity field on a 1D lattice, evolving through collisions that conserve momentum but do not conserve energy. Such a system possesses some of the main ingredients of ...

Evaluation of theoretical uncertainties in parity-violating electron scattering from nucleons and nuclei
(IOP Publishing Ltd., 2015-03-01)
Parity-violating polarized electron scattering from nucleons and nuclei provides an excellent tool to extract valuable information on nuclear and nucleon structure, as well as to determine Standard Model couplings and ...

Inferring divertor plasma properties from hydrogen Balmer and Paschen series spectroscopy in JET-ILW
(IOP Publishing, 2015-12)
A parametrised spectral line profile model is formulated to investigate the diagnostic scope for recovering plasma parameters from hydrogenic Balmer and Paschen series spectroscopy in the context of JET-ILW divertor ...

Progress in geant 4 electromagnetic physics modelling and validation
(IOP Publishing: Conference Series, 2015)
In this work we report on recent improvements in the electromagnetic (EM) physics models of Geant4 and new validations of EM physics. Improvements have been made in models of the photoelectric effect, Compton scattering, ...

Reaction dynamics induced by the radioactive ion beam 7Be on medium-mass and heavy targets
(American Institute of Physics, 2015)
We studied the reaction dynamics induced at Coulomb barrier energies by the weakly-bound Radioactive Ion Beam 7Be (Sα = 1.586 MeV) on medium-mass (58Ni) and heavy (208Pb) targets. The experiments were performed at INFN-LNL ...

L to H mode transition: parametric dependencies of the temperature threshold
(IOP Publishing, 2015-07)
The L to H mode transition occurs at a critical power which depends on various parameters, such as the magnetic field, the density, etc. Experimental evidence on various tokamaks (JET, ASDEX-Upgrade, DIII-D, Alcator C-Mod) ...

Three-dimensional non-linear magnetohydrodynamic modeling of massive gas injection triggered disruptions in JET
(AIP Publishing, 2015-07)
JOREK 3D non-linear MHD simulations of a D2 Massive Gas Injection (MGI) triggered disruption in JET are presented and compared in detail to experimental data. The MGI creates an overdensity that rapidly expands in the ...

The impact from survey depth and resolution on the morphological classification of galaxies
(Oxford University Press, 2015)
We consistently analyse for the first time the impact of survey depth and spatial resolution on the most used morphological parameters for classifying galaxies through non-parametric methods: Abraham and Conselice-Bershady ...

Anomalous self-diffusion in a freely evolving granular gas near the shearing instability
(American Physical Society, 2015)
The self-diffusion coefficient of a granular gas in the homogeneous cooling state is analyzed near the shearing instability. Using mode-coupling theory, it is shown that the coefficient diverges logarithmically as the ...
