The Physics of UHECRs: Spectra, Composition and the Transition Galactic-Extragalactic
, 2017 We review the experimental evidences about flux and mass composition of ultra high energy cosmic rays in connection with theoretical scenarios concerning astrophysical sources. In this context, we also address the discussion about the expected transition

Palamism Does Not Disfigure the Gospel: A Reply to Thomas Weinandy
International Journal of Systematic Theology, EarlyView.Abstract In a 2024 article in the IJST, Fr. Thomas Weinandy argues that the theological system of Gregory Palamas is in grave error, especially with respect to its commitment to an objective ontological distinction between God's essence and His energies. In his concluding paragraph Fr.

Noble gases and nitrogen in material from asteroid Bennu
Meteoritics &Planetary Science, EarlyView.Abstract We report the elemental and isotopic abundances of all stable noble gases (helium, neon, argon, krypton, and xenon) in eight particles from asteroid Bennu returned by NASA's OSIRIS‐REx mission. We also report nitrogen abundances and isotopic ratios that were analyzed alongside neon and argon in four additional Bennu particles.

Gamma-ray signatures of cosmic ray acceleration, propagation, and confinement in the era of CTA
, 2012 Galactic cosmic rays are commonly believed to be accelerated at supernova remnants via diffusive shock acceleration. Despite the popularity of this idea, a conclusive proof for its validity is still missing.

CI chondrite Oued Chebeika 002 links asteroids Bennu and Ryugu to common parent body
Meteoritics &Planetary Science, EarlyView.Abstract CI chondrites are a compositionally primitive group of meteorites that have undergone extensive aqueous alteration, providing insights into the evolution of primitive planetesimals. Oued Chebeika 002 is the most pristine CI chondrite to date.

Theoretical challenges in acceleration and transport of ultra high energy cosmic rays: A review
EPJ Web of Conferences, 2013 The wealth of data collected in the last few years thanks to the Pierre Auger Observatory and recently to the Telescope Array made the problem of the origin of ultra high energy cosmic rays a genuinely experimental/observational one.
