The Relativistic Outflow Driven by the Large-scale Magnetic Field from an Accretion Disk
The Astrophysical JournalOutflows/jets are ubiquitous in a wide range of astrophysical objects, yet the mechanisms responsible for their generation remain elusive. One hypothesis is that they are magnetically driven.

Steady relativistic fluid jets [PDF]
Monthly Notices of the Royal Astronomical Society, 1987 A numerical simulation is presented of a relativistic jet. Owing to the similar mathematical form of the equations of steady relativistic gas dynamics and steady non-relativistic gas dynamics, the numerical method used to make this calculation can be used to model either type of jet flow.

DECELERATING RELATIVISTIC TWO-COMPONENT JETS [PDF]
The Astrophysical Journal, 2009 Transverse stratification is a common intrinsic feature of astrophysical jets. There is growing evidence that jets in radio galaxies consist of a fast low density outflow at the jet axis, surrounded by a slower, denser, extended jet. The inner and outer jet components then have a different origin and launching mechanism, making their effective inertia,

Deconstructing Theory, Engaging Practice
Australian and New Zealand Journal of Family Therapy, Volume 47, Issue 1, March 2026.ABSTRACT This article revisits longstanding differences between modern and postmodern theory within systemic and family therapy and discusses its implications for practice. Drawing on Derrida's understanding of deconstruction as an ethical relation, it proposes a hospitable stance that holds theory lightly and irreverently, opening practice to multiple

Ions as Architects of DNA Nanostructures: Mechanisms, Simulations, and Technological Frontiers
Small Structures, Volume 7, Issue 3, March 2026.Ions are not merely passive electrolytes but active regulators of DNA nanostructures. This review shows how ion valence, hydration, and specificity govern electrostatic screening, correlation, and confinement, enabling DNA origami, metallized DNA, nanopores, hydrogels, DNAzymes, molecular machines, and energy devices through integrated experimental and

An Unusual Change in the Radio Jets of GRS 1915+105
The Astrophysical JournalWe compare Very Large Array observations of GRS 1915+105 made in 1994 and 2023, with nearly three decades of difference. The source has experienced intriguing major changes.

How do recollimation-induced instabilities shape the propagation of hydrodynamic relativistic jets?
Astronomy & AstrophysicsContext. Recollimation is a phenomenon of particular importance in the dynamical evolution of jets and in the emission of high-energy radiation. Additionally, the full comprehension of this phenomenon provides insights into fundamental properties of jets

Diffusion Coefficients for Resonant Relativistic Wave‐Particle Interactions Using the PIRAN Code
Earth and Space Science, Volume 13, Issue 3, March 2026.Abstract Quasilinear diffusion coefficients can be used to model the response of charged particles to resonant wave‐particle interactions. The calculation of these coefficients is sufficiently complicated and arduous to render it prohibitive to many potential users, because of the expense in time spent developing the code.
