Supernova remnants in the new radio astronomy era
A. Ingallinera, M. Arias, G. Castelletti +25
Supernova remnants (SNRs) are what is left after stellar explosions, when the stellar ejecta, the explosion shock and the circumstellar medium interact. Despite being among the fir…
A broadband view of the thermal and non-thermal emission from the embedded massive star cluster RCW 38
Giada Peron, Andrea Bracco, Giovanni Morlino +4
Gamma-ray emission has now been detected from a variety of source classes in the Galaxy, including clusters of young massive stars. RCW 38, a very young embedded massive star clust…
Particle acceleration at recollimation shocks in sub-relativistic jets A model for jets in Seyfert Galaxies, Microquasars and Protostellar Systems
Enrico Peretti, Elena Amato, Silvio Sergio Cerri +3
Context: Growing observational evidence suggests that sub-relativistic astrophysical jets may accelerate particles at slowly evolving standing shocks. Recollimation shocks are expe…
Probing hadronic gamma-ray and high-energy neutrino emission from Gaia DR2 star clusters
Alison M. W. Mitchell, Giovanni Morlino, Silvia Celli +2
Young and massive stellar clusters are a potential source of galactic cosmic rays due to at least two acceleration mechanisms. Collective stellar winds from massive stars form a wi…
Interpreting the LHAASO Galactic diffuse emission data
Vittoria Vecchiotti, Giada Peron, Elena Amato +4
Recently, the Large High-Altitude Air Shower Observatory (LHAASO) collaboration has obtained a measurement of the gamma-ray diffuse emission in the ultra-high energy range, $10-10^…
Hadronic acceleration in the young star cluster NGC 6611 inside the M16 region unveiled by Fermi-LAT: constraints on the acceleration efficiency
Giada Peron, Stefano Menchiari, Giovanni Morlino +1
Context. Young Massive Star Clusters, long considered as potentially important sources of galactic cosmic rays, have recently emerged as gamma-ray emitters up to very high energies…
