The Physics of Disk Winds, Jets,and X-ray Variability in GRS 1915+105
Disk Winds Jets X-ray Variability
2011/1/11
We present new insights about accretion and ejection physics based on joint RXTE/Chandra HETGS studies of rapid X-ray variability in GRS 1915+105. For the first time, with fast phase-resolved spectros...
The influence of collimation on the appearance of relativistic jets
collimation relativistic jets
2011/1/13
The question of the collimation of relativistic jets is the subject of a lively debate in the community. We numerically compute the apparent velocity and the Doppler factor of a non homokinetic jet us...
The evolution of the large-scale emission in FRI jets
galaxies jets–hydrodynamics–galaxies evolution–X-rays galaxies–gamma-rays galaxies–radio continuum galaxies
2010/11/11
Recent observations in X-rays and gamma-rays of nearby FRI radio galaxies have raised the question of the origin of the emission detected in the termination structures of their jets. The study of thes...
Quasi-Stationary and Transient Patterns in Jets
galaxies jets – stars binaries general – stars winds outflows
2010/11/10
Apparent evolution of relativistic flows as traced by radio emission results from a ombination of several factors related to propagation of relativistic blobs or shocks, velocity,density and pressure ...
Physical properties of blazar jets from VLBI observations
Cosmology and Extragalactic Astrophysics (astro-ph.CO) High Energy Astrophysical Phenomena (astro-ph.HE)
2011/1/5
Relativistic jets, formed in the vicinity of central supermassive black holes in AGN, show ample evidence connecting them to physical conditions in the accretion disc and broad-line region.
We present results on the magnetic field topology in a pulsed radiative jet.For initially helical magnetic fields and perio dic velo city variations, we find thatthe magnetic field alternates along th...
