Mainak Mukhopadhyay, Shunsaku Horiuchi

Relativistic outflows from accretion-induced white dwarf collapses can dominantly power the observed ultra-high-energy cosmic rays.

The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

AICs can dominantly power the observed UHECRs, if a majority of them host relativistic outflows. Accounting for uncertainties in the acceleration mechanisms and AIC rates, AICs can contribute ∼ a few 10^{43} - 10^{45} erg Mpc^{-3} yr^{-1} in UHECR energy generation rate density, assuming iron-like nuclei.

C2weakest assumption

That a majority of accretion-induced collapses produce relativistic outflows capable of efficient heavy-nuclei acceleration to UHECR energies, with the overall rate and efficiency adjustable within uncertainties to match observations.

C3one line summary

Relativistic outflows in accretion-induced collapse of white dwarfs are modeled as sources of UHECRs, contributing a few 10^43-10^45 erg Mpc^{-3} yr^{-1} assuming iron-like nuclei and sufficient event rates.
