Constraints on Hadronic Emission from Microquasars Detected by LHAASO
V. Vecchiotti, E. Amato, G. Giacinti +2
Recently, the LHAASO collaboration reported ultra-high-energy (UHE) gamma rays from six microquasars. For five of these sources, the emission extends beyond TeV, making micro…

Star clusters in the gamma-ray sky
Giada Peron
Massive Star Clusters (SCs) have been proposed as additional contributors to Galactic Cosmic rays (CRs), to overcome the limitations of supernova remnants (SNRs) to reach the highe…

Gamma-rays from Wolf-Rayet stellar winds
A. Inventar, G. Peron, S. Recchia +1
Gamma-ray observations of young star clusters have recently provided evidence for particle acceleration occurring at stellar wind termination shocks, fueled by the mechanical energ…
