Discovery of synchrotron emission from a YSO jet
EPJ Web of Conferences, 2013 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.

A Multidimensional Relativistic Hydrodynamics Code with a General Equation of State
, 2010 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.

A Modest Conception of Moral Right & Wrong
Analytic Philosophy, EarlyView.ABSTRACT Taking inspiration from Hume, I advance a conception of the part of morality concerned with right and wrong, rooted in the actual moral rules established and followed within our society. Elsewhere, I have argued this approach provides a way of thinking about how we are genuinely “bound in a moral way” to keep our moral obligations that it is ...

Relativistic Jets Shine through Shocks or Magnetic Reconnection [PDF]
, 2015 Observations of gamma-ray-bursts and jets from active galactic nuclei reveal that the jet flow is characterized by a high radiative e ffi ciency and that the dissipative mechanism must be a powerful accelerator of non-thermal particles.

Meaning, anti‐alienation, and fulfillment
The Southern Journal of Philosophy, EarlyView.Abstract One intuition that motivates subjectivist theories about meaning in life is the anti‐alienation intuition, that is, for a life to be meaningful it must engage with the person whose life it is. This article contends that the anti‐alienation and subjectivist theories it motivates are best understood as tracking fulfillment in life; this is an ...

Some Notes About the Current Researches on the Physics of Relativistic Jets
Frontiers in Astronomy and Space Sciences, 2022 Some highlights of the recent researches in the field of relativistic jets are reviewed and critically analyzed. Given the extent of the available literature, this essay symbolically takes the baton from the outstanding and recent review by Blandford ...

Formation of precessing jets by tilted black hole discs in 3D general relativistic MHD simulations [PDF]
, 2017 Gas falling into a black hole (BH) from large distances is unaware of BH spin direction, and misalignment between the accretion disc and BH spin is expected to be common. However, the physics of tilted discs (e.g.

Geophysical Research Letters, Volume 52, Issue 23, 16 December 2025.Abstract The strong very high frequency (VHF) radiation from compact intra‐cloud discharges (CIDs) is attributed to streamers. An analytical model, taking altitude and applied electric field as input, is developed for effective representation of current for a double‐headed exponentially growing streamer.

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