Stability of Relativistic Jets from Rotating, Accreting Black Holes via Fully Three-Dimensional Magnetohydrodynamic Simulations

Jonathan C. McKinney, Roger D. Blandford

Rotating magnetized compact objects and their accretion discs can generate strong toroidal magnetic fields driving highly magnetized plasmas into relativistic jets. Of significant…

An Atlas For Interpreting Gamma-Ray Pulsar Light Curves

Kyle P. Watters, Roger W. Romani, Patrick Weltevrede +1

We have simulated a population of young spin-powered pulsars and computed the beaming pattern and lightcurves for the three main geometrical models: polar cap emission, two-pole ca…

Fermi LAT Observations of the Vela Pulsar

A. A. Abdo

The Vela pulsar is the brightest persistent source in the GeV sky and thus is the traditional first target for new gamma-ray observatories. We report here on initial Fermi Large Ar…

Large-scale horizontal flows in the solar photosphere. IV. On the vertical structure of large-scale horizontal flows

Michal Svanda, Mirek Klvana, Michal Sobotka +2

In the recent papers, we introduced a method utilised to measure the flow field. The method is based on the tracking of supergranular structures. We did not precisely know, whether…
