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…
Modelling Galactic neutrino emission: contributions from massive star clusters and interstellar cosmic rays
Stefano Menchiari, Silvia Celli, Vittoria Vecchiotti +3
The recent detection of Galactic neutrinos by the IceCube Observatory constitutes a remarkable achievement for neutrino astrophysics. By means of model dependent analyses based on…
Multimessenger Concordance for the Cygnus Region as the Source of the Cosmic-Ray Knee
Luis E. Espinosa Castro, Kotha Murase, Carlo Rizza +3
The origin of the cosmic-ray (CR) knee remains one of the central open questions in particle astrophysics. Recent measurements by the Large High Altitude Air Shower Observatory rev…
Gamma-ray Orbital Modulation in Spider Pulsars: Three Discoveries and a Universal Modulated Fraction
Maksat Satybaldiev, Manuel Linares, Vittoria Vecchiotti
Compact binary millisecond pulsars (also known as spiders) allow us to probe pulsar winds in their innermost regions, between the light cylinder (radius cm) and the co…
Search for Diffuse Galactic Neutrinos with the Full ANTARES Telescope Dataset
ANTARES Collaboration, Pedro De la Torre Luque, Daniele Gaggero +4
The diffuse emission of gamma-rays and neutrinos, produced by interactions of cosmic rays with interstellar matter in the Milky Way, provides valuable insights into cosmic ray prop…
Very high-energy gamma-ray and neutrino emission from hadronic interaction in compact binary millisecond pulsars
Vittoria Vecchiotti, Manuel Linares
Blackwidow and redback systems are millisecond pulsars in compact orbits with ultra-light and low-mass companions, respectively, collectively known as ``spider pulsars". In such sy…
