Jets from Scratch: Dynamo-generated Poloidal Magnetic Fields in Three-dimensional Collapsar Simulations

open access: yesThe Astrophysical Journal Letters
The origin of the large-scale poloidal magnetic field required to power relativistic jets in collapsars remains uncertain. While such a field may be inherited during proto-neutron-star collapse, the efficiency of this process is unclear, motivating an in

Axiomatizing relativistic dynamics without conservation postulates [PDF]

open access: yes, 2008
A part of relativistic dynamics (or mechanics) is axiomatized by simple and purely geometrical axioms formulated within first-order logic. A geometrical proof of the formula connecting relativistic and rest masses of bodies is presented, leading up to a ...

Relativistic Jet Motion in the Radio-quiet LINER Galaxy KISSR 872

open access: yesThe Astrophysical Journal
We report superluminal jet motion with an apparent speed of β _app = 1.65 ± 0.57 in the radio-quiet (RQ) low-ionization nuclear emission-line region (LINER) galaxy KISSR 872.
