“…NuSTAR can provide a better determination of the spectrum from both regions in this regime. In the MeV-GeV band, planned telescopes such as GRAMS (Aramaki et al 2020), e-ASTROGAM (De Angelis et al 2017), andAMEGO (McEnery et al 2019) will be able to study the highest energy synchrotron photons, though the localization of emitting region would be difficult for their expected angular resolutions. Our models predict that these observations would detect spectral turnover and cutoff (Fig.…”

SS433 is a Galactic microquasar with powerful jets, where very-high-energy particles are produced. We study particle acceleration in the jets of SS433 in the light of the recent multi-wavelength data from radio to TeV gamma ray. We first present a general framework for the particle acceleration, cooling, and transport in relativistic jets. We then apply this to two X-ray knots in the jets of SS433, focusing on leptonic emission. Our detailed treatment of particle transport and evolution produces substantially different predictions from previous papers. For both regions, our model can account for the multi-wavelength data except for the GeV data. This suggests that GeV emission is mostly from different regions and/or mechanisms. We find that the acceleration process should be efficient, which could be realized by diffusive shock acceleration close to the Bohm limit. Provided that protons are accelerated at the same efficiency as electrons, our results imply that SS433 is a PeVatron, i.e., can accelerate protons beyond a PeV. Future hard X-ray and MeV gamma-ray observations can critically test our models by detecting the spectral turnover or cutoff.

“…could be used as reference to calibrate the low energy gamma-ray telescope proposed for the next decade, such as ASTROGAM [15,16] and AMEGO [17]. At energies above tens of GeV the calculated fluxes exhibit some fluctuations that are due to the limited statistic in the simulated data sets.…”

“…In particular, we have simulated the interactions of protons, helium nuclei and electrons impinging on the solar atmosphere in a wide energy range from 0.1 GeV/n to 100 TeV/n, while the energy of secondary particles has been simulated down to 100 keV. The low-energy region is extremely interesting for the proposed future gammaray telescopes [15][16][17], which aim to probe photon energy intervals extending well below the lower bound of that explored by the Fermi Large Area Telescope (a few tens of MeV) [18].…”

Cosmic-ray interactions with the Sun using the fluka code

et al. 2020

The interactions of cosmic rays with the solar atmosphere produce secondary particle which can reach the Earth. In this work we present a comprehensive calculation of the yields of secondary particles as gamma-rays, electrons, positrons, neutrons and neutrinos performed with the FLUKA code. We also estimate the intensity at the Sun and the fluxes at the Earth of these secondary particles by folding their yields with the intensities of cosmic rays impinging on the solar surface. The results are sensitive on the assumptions on the magnetic field nearby the Sun and to the cosmic-ray transport in the magnetic field in the inner solar system.

“…In particular, our model predicts a corresponding -ray bump at ∼10-100 MeV (Figure 2). This can be tested with -ray observatories in the near future (e.g., AMEGO, e-ASTROGAM; De Angelis et al 2017;McEnery 2017).…”

Spectral energy distribution modeling of broadband emission in the pulsar wind nebula 3C 58

We investigate the broadband emission properties of the pulsar wind nebula (PWN) 3C 58 using a spectral energy distribution (SED) model. We attempt to match simultaneously the broadband SED and spatial variations of X‐ray emission in the PWN. We further use the model to explain a possible far‐IR feature of which a hint was recently suggested in 3C 58: a small bump at ∼1011 GHz in the PLANCK and Herschel bands. While external dust emission may easily explain the observed bump, it may be the internal emission of the source, implying an additional population of particles. Although significance for the bump is not high, here we explore possible origins of the IR bump using the emission model, and find that a population of electrons with GeV energies can explain it. If it is produced in the PWN, it may provide new insights into particle acceleration and flows in PWNe.
