Published data on unconfined plane-wall jets and plane-free jets were reviewed and used to assess the accuracy of numerical simulations, A plane-free jet was numerically simulated using the standard k-e model and four nonuniform grid patterns (70 x32,100 x52,120 x 60, and 120 x 74), The solution for a plane-free jet with adequate grid resolution was in good agreement with the published data, A ...

We present steady-state calculations of self-similar magnetized accretion discs driving cold, adiabatic, non-relativistic jets. For the first time, both the magnetic torque due to the jets and a turbulent “viscous” torque are taken into account. This latter torque allows a dissipation of the accretion power as radiation at the disc surfaces, while the former predominantly provides jets with pow...

We developed theory of particle acceleration inside the relativistic rotating electronpositron force–free jet with spiral magnetic field. We considered perturbation of stationary magnetic field structure and found that acceleration takes place in the regions where the Alfvén resonant condition with the eigenmodes in the jet is fulfilled, i.e. where the local Alfvén speed is equal to the phase s...

This paper presents a novel method of searching for boosted hadronically decaying objects by treating them as anomalous elements contaminated dataset. A Variational Recurrent Neural Network (VRNN) is used to model jets sequences constituent four-vectors. After applying pre-processing which boosts each jet the same reference mass and energy, VRNN provides an Anomaly Score that distinguishes betw...

Rook theory has been investigated by many people since its introduction by Kaplansky and Riordan in 1946. Goldman, Joichi and White in 1975 showed that the sum over k of the product of the (n− k)-th rook numbers multiplied by the k-th falling factorial polynomials factorize into a product. In the sequel, different types of generalizations and analogues of this product formula have been derived ...

We present deep JVLA observations at 1.4 GHz and 2.7 (full polarization), as well optical OmegaWINGS/WINGS X-ray of two extended radio galaxies in the IIZW108 galaxy cluster z = 0.04889. They show a bent tail morphology agreement with lobed falling into potential. Both are found to possess properties comparable {narrow-angle} literature even though they part low mass cluster. find spectral inde...
