The last century has seen enormous progress in our understanding of the Universe. We know life cycles stars, structure galaxies, remnants big bang, and have a general how Universe evolved. come remarkably far using electromagnetic radiation as tool for observing However, gravity is engine behind many processes Universe, much its action dark. Opening gravitational window on will let us go further than any alternative. Gravity own messenger: Gravitational waves, ripples fabric spacetime. They...

Abstract The measurement of cosmic-ray individual spectra provides unique information regarding the origin and propagation astro-particles. Due to limited acceptance current space experiments, protons nuclei around “knee” region (∼ 1 PeV) can only be observed by ground based experiments. Thanks an innovative design, High Energy cosmic-Radiation Detection (HERD) facility will allow direct observation up this energy region: instrument is mainly on a 3D segmented, isotropic homogeneous...

Current research in High Energy Cosmic Ray Physics touches on fundamental questions regarding the origin of cosmic rays, their composition, acceleration mechanisms, and production. Unambiguous measurements energy spectra composition rays at "knee" region could provide some answers to above questions. So far only ground based observations, which rely sophisticated models describing high interactions earth's atmosphere, have been possible due extremely low particle rates these energies. A...
