Measurement of the cosmic ray flux by an ArduSiPM-based muon telescope in the framework of the Lab2Go project [PDF]

, 2023
Within Istituto Nazionale di Fisica Nucleare (INFN) outreach activities, the Lab2Go project is of great significance. Its goal is involving high school teachers and students in several laboratory activities, aiming at increasing the weight of ...

A critical note on time in the multiverse [PDF]

, 2013
In recent analyses of standard, single-universe, cosmology, it was pointed out that specific assumptions regarding the distribution and motion of matter must be made in order to set up the cosmological standard model with a global time parameter. Relying

Ionization in atmospheres of brown dwarfs and extrasolar planets. IV. The effect of cosmic rays [PDF]

, 2013
Cosmic rays provide an important source for free electrons in Earth's atmosphere and also in dense interstellar regions where they produce a prevailing background ionization. We utilize a Monte Carlo cosmic ray transport model for particle energies of 10(

Triangulating the height of cosmic noise absorption: A method for estimating the characteristic energy of precipitating electrons [PDF]

, 2010
Energetic electrons (tens to hundreds of keV) deposit significant energy into the D layer of the ionosphere. Riometers provide a means of monitoring this electron precipitation by measuring the associated cosmic noise absorption (CNA), but individually ...

Integrated geophysical‐petrological modeling of lithosphere‐asthenosphere boundary in central Tibet using electromagnetic and seismic data

Geochemistry, Geophysics, Geosystems, 2014
We undertake a petrologically driven approach to jointly model magnetotelluric (MT) and seismic surface wave dispersion (SW) data from central Tibet, constrained by topographic height. The approach derives realistic temperature and pressure distributions

Probing the high latitude ionosphere from ground-based observations: The state of current knowledge and capabilities during IPY (2007-2009) [PDF]

, 2008
During the International Polar Year (IPY), one area of great interest is co-coordinated, multi-instrument probing of the ionosphere at high latitudes. This region is important not only for the applications that rely upon our understanding of it, but also

The attenuation of atmospheric Cerenkov photons [PDF]

, 2002
Whilst the atmosphere places a limit on the successful applications of many branches of astronomy, it becomes an invaluable tool for the detection of very high energy γ-rays. This thesis is concerned with reducing the systematic uncertainties inherent to

The Slab Puzzle of the Alpine‐Mediterranean Region: Insights From a New, High‐Resolution, Shear Wave Velocity Model of the Upper Mantle

Geochemistry, Geophysics, Geosystems, 2020
Mediterranean tectonics since the Lower Cretaceous has been characterized by a multiphase subduction and collision history with temporally and spatially variable, small‐scale plate configurations.
