Annalen der Physik, EarlyView.The BRST invariant Lagrangian of the gravitationally interacting U(1)$U(1)$ gauge theory, namely the Quantum GraviElectro Dynamics (QGED). The Yan–Mills theory with the Hilbert–Einstein gravitational Lagrangian, namely the Yang–Mills–Utiyama (YMU) theory, is defined and quantised using the standard procedure. The theory is perturbatively renormalisable,

Synchrotron Radiation Maps from Relativistic MHD Jet Simulations
Galaxies, 2017 Relativistic jets from active galactic nuclei (AGN) often display a non-uniform structure and are, under certain conditions, susceptible to a number of instabilities.

Characterization of Jets in Relativistic Heavy Ion Collisions
, 2003 Jet quenching is considered to be one of the signatures of the formation of quark gluon plasma. In order to investigate the jet quenching, it is necessary to detect jets produced in relativistic heavy ion collisions, determine their properties and ...

Small, EarlyView.The synthesis of Au and Au2O3 stable nanoparticles through non‐thermal and low‐pressure plasma approach is explored. Furthermore, their performance as multi‐sensing platforms for NADH and H2O2 under real biological conditions is tested. Abstract In this work, a plasma‐assisted and solvent‐free synthesis of gold (Au) and gold oxide (Au2O3) nanoparticles

The Astrophysical JournalBoth observational evidence and theoretical considerations from magnetohydrodynamic simulations of jets suggest that the relativistic jets of active galactic nuclei (AGN) are radially stratified, with a fast inner spine surrounded by a slower-moving ...

Relativistic Jets from AGN Viewed at Highest Angular Resolution
, 2019 Accreting supermassive black holes in active galactic nuclei (AGN) produce powerful relativistic jets that shine from radio to GeV/TeV γ-rays. Over the past decade, AGN jets have extensively been studied in various energy bands and our knowledge about ...

Formation of relativistic MHD jets: stationary state solutions & numerical simulations [PDF]
, 2008 We discuss numerical results of relativistic magnetohydrodynamic (MHD) jet formation models. We first review some examples of stationary state solutions treating the collimation and acceleration process of relativistic MHD jets.

The power of relativistic jets is larger than the luminosity of their accretion disks [PDF]
Nature, 2014 Theoretical models for the production of relativistic jets from active galactic nuclei predict that jet power arises from the spin and mass of the central supermassive black hole, as well as from the magnetic field near the event horizon.

A Theory of Leadership Meta‐Talk and the Talking‐Doing Gap
Journal of Management Studies, EarlyView.Abstract We identify managers' meta‐level talk about the positive purpose, meaning, and significance of their actions as an overlooked type of leadership behaviour and call it leadership meta‐talk. We outline why leadership meta‐talk is not necessarily truthful or deceptive, but selective and loosely coupled with leadership practice.

Electron jets in toroidal self-generated magnetic fields of nonextensive laser-produced plasma
AIP AdvancesUnder the framework of nonextensive distribution, the modulation instabilities of annular self-generated magnetic fields and electron jets formed during laser-plasma interactions under both relativistic and non-relativistic conditions have been ...
