A Multidimensional Relativistic Hydrodynamics Code with a General Equation of State
The ideal gas equation of state with a constant adiabatic index, although commonly used in relativistic hydrodynamics, is a poor approximation for most relativistic astrophysical flows.

Discovery of synchrotron emission from a YSO jet
Synchrotron emission at radio wavelengths is commonly found in relativistic jets from active galactic nuclei (AGNs) and microquasars and allows the study of the magnetic field in these kind of jets.

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,

CHANDRA Observations of X-ray Jet Structure on kpc to Mpc Scales
With its exquisite spatial resolution of better than 0.5 arcsecond, the Chandra observatory is uniquely capable of resolving and studying the spatial structure of extragalactic X-ray jets on scales of a few to a few hundred kilo-parsec.

Revival of Layered Ferroelectrics in Thin Films
This review presents recent advances in layered perovskite‐based ferroelectric thin films, showing how progress in deposition and characterization now enables atomic‐precision synthesis across the Aurivillius, Carpy–Galy, Ruddlesden–Popper, and Dion–Jacobson families.

Signatures of Relativistic Helical Motion in the Rotation Measures of AGN Jets
Polarization has proved an invaluable tool for probing magnetic fields in relativistic jets. Maps of the intrinsic polarization vectors have provided the best evidence to date for uniform, toroidally dominated magnetic fields within jets.

The Relativistic Outflow Driven by the Large-scale Magnetic Field from an Accretion Disk
Outflows/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]
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]
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,

Abstract Earth's outer radiation belt electron flux is highly variable and can be enhanced by over an order of magnitude over timescales less than one day, as observed during the October 2012 storm. Previous studies of this storm (e.g., Reeves et al., 2013, https://doi.org/10.1126/science.1237743) have invoked local acceleration to explain this ...
