ǂThe ǂgalactic population of pulsar wind nebulae and the contribution of its unresolved component to the diffuse high-energy gamma-ray emission
Giulia Pagliaroli, S. Hussain, Vittoria Vecchiotti, Francesco Lorenzo Villante

Oznake: pulsar wind nebulae;neutrinos;gamma-rays;multimessenger astronomy;
In this work, we provide a phenomenological description of the population of galactic TeV pulsar wind nebulae (PWNe) based on suitable assumptions for their space and luminosity distribution. We constrain the general features of this population by assuming that it accounts for the majority of bright ...

In the hypothesis that the majority of bright TeV sources detected by H.E.S.S. are powered by pulsar activity, like, e.g., pulsar wind nebulae (PWN) or TeV halos, we estimate the main properties of the Galactic pulsar population. We obtain constraints on the spin-down time τsd, the initial period P0 ...

Neutrinos and gamma rays from galaxy clusters constrained by the upper limits of IceCube

Oznake: galaxy cluster;cosmic rays;gamma rays;neutrinos;
Clusters of galaxies possess the capability to accelerate cosmic rays (CRs) to very high energy up to ∼1018 eV due to their large size and magnetic field strength, which favor CR confinement for cosmological times. During their confinement, they can produce neutrinos and γ-rays out of interactions w ...

High-energy neutrino and gamma ray production in clusters of galaxies

We compute the contribution from clusters of galaxies to the diffuse neutrino and γ− ray background. Due to their unique magnetic-field configuration, cosmic rays (CRs) with energy ≤1e17 eV can be confined within these structures over cosmological time scales, and generate secondary particles, inc ...
