Tīmeklis2008. gada 1. nov. · Abstract I describe various stages of energy flow along an extragalactic jet, which subsequently evolves into an extended lobe which is visible in radio and X-rays. The sizes of the lobes vary from kpc scales to several megaparsec, so that the largest lobes are clearly injecting back hole energy into the IGM on … Tīmeklis2024. gada 2. apr. · FRII radio galaxies have powerful jets, which remain highly focused before terminating abruptly and inflating lobes of highly turbulent jet material (see left image of Figure 1). Hotspots- regions of intense radio emission, mark the location where the jets terminate. FRII jets are brightest at their leading edges.

Tīmeklis2016. gada 22. sept. · Cosmic Magnetic Fields - October 2016 A radio galaxy is a galaxy with giant regions of radio emission extending well beyond its visible structure. These energetic radio lobes are powered by jets from its active galactic nucleus. They have luminosities up to 10 W at radio wavelengths between 10 MHz and 100 GHz. The radio emission is due to the synchrotron process. The observed structure in radio emission is determined … product service delivery definition

We resolve the very narrow and straight tail of CR 15 without indication of double jets, so that the interpretation of such head-tail sources is yet unclear.

The reigning paradigm in this field, which dates back to early classic works by for example Longair, Ryle & Scheuer (1973) and Scheuer (1974), is that intrinsically both lobes have similar properties.
