Espresso and Stochastic Acceleration of Ultra-high-energy Cosmic Rays in Relativistic Jets [PDF]
Astrophysical Journal, 2021 In the espresso scenario, ultra-high-energy (UHE) cosmic rays (CRs) are produced via a one-shot reacceleration of galactic-like CRs in the relativistic jets of active galactic nuclei, independently of the scattering rate dictated by magnetic fluctuations.

The propagation of relativistic jets in expanding media [PDF]
Monthly notices of the Royal Astronomical Society, 2021 We present a comprehensive analytic model of relativistic jet propagation in expanding homologous media (ejecta). This model covers the entire jet evolution as well as a range of configurations that are relevant to binary neutron star mergers.

A Simulation Study of Ultra-relativistic Jets–I. A New Code for Relativistic Hydrodynamics [PDF]
Astrophysical Journal, 2021 In an attempt to investigate the structures of ultra-relativistic jets injected into the intracluster medium (ICM) and the associated flow dynamics, such as shocks, velocity shear, and turbulence, we have developed a new special relativistic hydrodynamic

The Powers of Relativistic Jets Depend on the Spin of Accreting Supermassive Black Holes [PDF]
, 2021 Theoretical models show that the power of relativistic jets of active galactic nuclei depends on the spin and mass of the central supermassive black holes, as well as the accretion.

Absorbed relativistic jets in radio-quiet narrow-line Seyfert 1 galaxies [PDF]
Astronomy & Astrophysics, 2020 Narrow-line Seyfert 1 (NLS1) galaxies are peculiar active galactic nuclei. Most of them do not show strong radio emission, but seven radio-quiet (or radio-silent) NLS1s have recently been detected flaring multiple times at 37 GHz by the Metsähovi Radio ...

Kink instabilities in relativistic jets can drive quasi-periodic radiation signatures [PDF]
, 2020 Relativistic jets are highly collimated plasma outflows emerging from accreting black holes. They are launched with a significant amount of magnetic energy, which can be dissipated to accelerate nonthermal particles and give rise to electromagnetic ...

SDSS J211852.96−073227.5: The first non-local, interacting, late-type intermediate Seyfert galaxy with relativistic jets [PDF]
Astronomy & Astrophysics, 2020 It has been often suggested that a tangible relation exists between relativistic jets in active galactic nuclei (AGN) and the morphology of their host galaxies. In particular, relativistic jets may commonly be related to merging events.

Israel Journal of Chemistry, Volume 62, Issue 11-12, December 2022., 2022 Abstract Electrons ransported through a chiral molecule become spin−polarized; this phenomenon is known as chiral induced spin selectivity (CISS). It has implications for spintronics, for electrochemical and enantioselective reactions, and for electron transfer in biological systems.

Chirality Induced Spin Selectivity – the Photoelectron View
Israel Journal of Chemistry, Volume 62, Issue 11-12, December 2022., 2022 Abstract In this short overview we discuss the manifestation of the chirality‐induced spin selectivity (CISS) effect in photoelectron spectroscopy experiments with direct spin analysis. Various systems, from the initially investigated monolayers of molecular biosystems and organic hepta‐helicene to recent chirally grown solid oxide films, are evaluated.

Ray-Tracing in Relativistic Jet Simulations: A Polarimetric Study of Magnetic Field Morphology and Electron Scaling Relations [PDF]
A&A 656, A143 (2021), 2021 The jets emanating from the centers of active galactic nuclei (AGN) are among the most energetic objects in the universe. Investigating how the morphology of the jet's synchrotron emission depends on the magnetic nature of the jet's relativistic plasma is fundamental to the comparison between numerical simulations and the observed polarization of ...
