Radiation from Relativistic Jets [PDF]
, 2008 Nonthermal radiation observed from astrophysical systems containing relativistic jets and shocks, e.g., gamma-ray bursts (GRBs), active galactic nuclei (AGNs), and Galactic microquasar systems usually have power-law emission spectra.

Polarized Emission from Gamma-Ray Burst Jets
Galaxies, 2017 I review how polarization signals have been discussed in the research field of Gamma-Ray Bursts (GRBs). I mainly discuss two subjects in which polarimetry enables us to study the nature of relativistic jets.

Extragalactic relativistic jets [PDF]
AIP Conference Proceedings, 2011 Extragalactic relativistic jets are engines able to carry out to large distances a huge amount of power, not only in the form of radiation, but especially in the form of kinetic energy of matter and fields. As such, they can be thought as one of the most efficient engines of Nature, perhaps even more efficient than accretion.

Dreams, Scepticism and Idealism
Theoria, EarlyView.ABSTRACT On one narrative, Berkeleyan idealism arises from Cartesian theorising: Descartes's discussion of dreaming in the Meditations leads first to scepticism, and through scepticism, to Berkeley's rejection of realism. In this paper, I consider how this move from dreams to idealism is supposed to work.

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 ...

Journal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 5, October 2026.Abstract Magnetic reconnection at the dayside magnetopause is the primary pathway for transferring mass, momentum, and energy from the solar wind into the terrestrial magnetosphere. Previous studies have shown that the spatiotemporal dynamics of dayside magnetic reconnection can be inferred remotely from properties of Earth's cusps, specifically their ...

Beyond the Impulsive Approximation: The Dynamics and Radio Emission of Tidal Disruption Jets
The Astrophysical Journal LettersRadio emission from relativistic tidal disruption events (TDEs) is commonly interpreted using the Blandford–McKee solution for an impulsive relativistic blast wave.

A Panchromatic View of Relativistic Jets in Narrow-Line Seyfert 1 Galaxies
Galaxies, 2016 The discovery by the Large Area Telescope on board Fermi of variable γ-ray emission from radio-loud narrow-line Seyfert 1 (NLSy1) galaxies revealed the presence of a possible third class of Active Galactic Nuclei (AGN) with relativistic jets in addition ...

Earth and Space Science, Volume 13, Issue 10, October 2026.Abstract Very Low Earth Orbit (VLEO) satellite platforms and quantum‐optical sensing technologies may provide new observation approaches for improving Earth's static gravity field models. This study conceptually assesses their potential contribution through a two‐tier closed‐loop simulation framework.
