Q-NONTHERMAL-PARTICLE-TRANSPORT · provisional_seed

How are high-energy particles accelerated, escaped, and transported through compact sources, galaxies, and diffuse media to produce discriminating non-thermal emission?

Scope

In scope

Cosmic rays, gamma-ray binaries, diffuse galactic gamma rays, non-thermal radio/X-ray emission, and neutrino production.

Out of scope

Transient detections without a constraint on particle physics or transport.

Why it matters

Determines whether high-energy feedback, diffuse backgrounds, and multimessenger source interpretations are mutually consistent.

Competing explanations

  • Hadronic processes dominate
  • Leptonic processes dominate
  • Diffusion dominates transport
  • Advection or winds dominate transport
  • Local source environments rather than global media set the spectrum

Discriminating observables

  • Broadband spectral energy distributions
  • Spatial extent and energy-dependent morphology
  • Joint gamma-ray, radio, X-ray, and neutrino constraints

Blockers

  • Source confusion
  • Magnetic-field and gas-density uncertainty
  • Spatially varying diffusion
  • Leptonic-hadronic spectral degeneracy

Accepted evidence routing

GeV γ-ray emission in the star-forming region S140

The jet driven by S140 IRS1 offers a viable particle acceleration site, yielding injection timescales and maximum particle energies consistent with theoretical expectations, whereas stellar winds are energetically disfavored.
