We present numerical simulation of bulk Lorentz factor of relativistic electronpositron jet driven by Compton rocket effect from accretion disk radiation. The plasma is assumed to have a power-law distribution ne(γ) ∝ γ −s ( 1 < γ < γmax) and is continuously reheated to compensate radiation losses. We include Klein-Nishina (hereafter KN) corrections, and study the role of energy upper cut-off γ...

We study the holomorphic twist of 3d $$\mathcal{N}=2$$ gauge theories in presence boundaries, and algebraic structure bulk boundary local operators. In twist, both operators form chiral algebras (a.k.a. vertex algebras). The algebra is commutative, endowed with a shifted Poisson bracket “higher” stress tensor; while module for bulk, may not be or have tensor. explicitly construct free Landau–Gi...

Strong γ-ray emission from cocoons of young radio galaxies is newly predicted. Considering the process of adiabatic injection of the shock dissipation energy and mass of the relativistic jet in active nuclei (AGNs) into the cocoon, while assuming thermalizing electron plasma interactions, we find that the thermal electron temperature of the cocoon is typically predicted in ∼MeV, which is determ...

The paper proposes an amendment to the relativistic continuum mechanics which introduces relationship between density tensors and curvature of spacetime. resulting formulation a symmetric stress–energy tensor for system with electromagnetic field leads solution Einstein Field Equations indicating metric tensor. In this EFE solution, cosmological constant is related invariant tensor, additional ...

The Douglas–Kroll transformed Dirac–Coulomb Hamiltonian is used to describe scalar-relativistic effects in solids. A Hartree–Fock approximation with periodic boundary conditions makes it feasible to use methods originally developed for atoms and molecules to solve the corresponding equations for crystalline systems. The implementation is realized within the CRYSTAL program. Scalar-relativistic ...

A property common to several different astrophysical sources of high-energy gamma-rays is the presence of bulk motion at relativistic speed. The intrinsic spectra of the nonthermal radiating particles also show interesting similarities, with a pronounced hardening towards lower energies. This suggests two distinct acceleration mechanisms could be at work in these sources. At high energies, the ...
