The ARGO-YBJ legacy to next generation wide field-of-view experiments
The ARGO-YBJ experiment has been in stable data taking for more than 5 years at the YangBaJing Cosmic Ray Observatory (Tibet, P.R. China, 4300 m a.s.l., 606 g/cm2).

Measuring the ionisation fraction in a jet from a massive protostar
The ionisation fraction of protostellar jets is key to establish their true energetics. Here, the authors determine it in a jet from a high-mass young stellar object, using multi-wavelengths observations, confirming that the ionising mechanism giving ...

Status and recent high light results from the LHAASO experiment [PDF]
The Large High Altitude Air Shower Observatory (LHAASO) experiment, fully operational since July 2021, is a cutting-edge facility for detecting cosmic rays and gamma rays across a wide energy range. This paper offers an overview of the current status and

Turning AGN Bubbles into Radio Relics with Sloshing: Modeling CR Transport with Realistic Physics
Radio relics are arc-like synchrotron sources at the periphery of galaxy clusters, produced by cosmic-ray electrons in a μG magnetic field, which are believed to have been (re-)accelerated by merger shock fronts.

Propagation of Cosmic Rays: Nuclear Physics in Cosmic-Ray Studies [PDF]
The nuclei fraction in cosmic rays (CR) far exceeds the fraction of other CR species, such as antiprotons, electrons, and positrons. Thus the majority of information obtained from CR studies is based on interpretation of isotopic abundances using CR propagation models where the nuclear data and isotopic production cross sections in p- and alpha-induced

Solar and nuclear physics uncertainties in cosmic-ray propagation [PDF]
Recent data released by the AMS experiment on the primary spectra and secondary-to-primary ratios in cosmic rays (CRs) can pose tight constraints to astrophysical models of CR acceleration and transport in the Galaxy, thereby providing a robust baseline ...

Physics of Cosmic Masers [PDF]
Natural masers, which emit powerful narrow-band radiation in molecular microwave lines, were discovered about 20 years ago. They draw the astrophysicist's attention in two ways: 1) as a unique physical phenomenon and 2) as very informative probes of physical conditions in those astrophysical objects (very young and very old stars) with which they are ...
