Key Details

•

S26 jets have kinetic luminosity of 10^40 erg/s

•

X-ray luminosity is 10^37 erg/s, much lower than expected

•

We suggest disk emission absorbed by wind, spin energy helps power jet

•

Analyze XMM-Newton data, emission has thermal and non-thermal origin

•

Protons accelerated in lobes can reach 10 PeV energies

XMM-Newton observations of the jet power and particle acceleration in the microquasar S26

The microquasar S26 has very powerful jets, indicating a super-Eddington accretion rate. However, X-ray observations show much lower luminosity than expected. We analyze XMM-Newton data, propose the disk emission is absorbed, additional spin energy powers the jet, and show particles can reach PeV energies.
