Jet propagation through inhomogeneous media and shock ionization

چکیده

Abstract In this contribution, we present the first numerical simulations of a relativistic outflow propagating through inner hundreds parsecs its host galaxy, including atomic and ionized hydrogen, cooling effects ionization. Our results are preliminary, but observe efficient shock ionization hydrogen in interstellar clouds. The mean density medium these initial is lower than that expected typical galaxies, which makes times longer thus no recombination observed inside shocked region. velocities achieved by gas agreement with observational results, although wide spectrum values.

Wave Propagation and Blocking in Inhomogeneous Media

Wave propagation governed by reaction-diffusion equations in homogeneous media has been studied extensively, and initiation and propagation are well understood in scalar equations such as Fisher’s equation and the bistable equation. However, in many biological applications the medium is inhomogeneous, and in one space dimension a typical model is a series of cells, within each of which the dyna...

Modeling of wave propagation in inhomogeneous media.

We present a methodology providing a new perspective on modeling and inversion of wave propagation satisfying time-reversal invariance and reciprocity in generally inhomogeneous media. The approach relies on a representation theorem of the wave equation to express the Green function between points in the interior as an integral over the response in those points due to sources on a surface surro...

Propagation of Reactions in Inhomogeneous Media

Consider reaction-diffusion equation ut = ∆u+f(x, u) with x ∈ R and general inhomogeneous ignition reaction f ≥ 0 vanishing at u = 0, 1. Typical solutions 0 ≤ u ≤ 1 transition from 0 to 1 as time progresses, and we study them in the region where this transition occurs. Under fairly general qualitative hypotheses on f we show that in dimensions d ≤ 3, the Hausdorff distance of the super-level se...

Traveling Pulses and Wave Propagation Failure in Inhomogeneous Neural Media

We use averaging and homogenization theory to study the propagation of traveling pulses in an inhomogeneous excitable neural network. The network is modeled in terms of a nonlocal integrodifferential equation, in which the integral kernel represents the spatial distribution of synaptic weights. We show how a spatially periodic modulation of homogeneous synaptic connections leads to an effective...
