Jet/environment Interactions of Fr-i and Fr-ii Radio Galaxies
We present the results of new XMM observations of FR-I and FR-II radio galaxies that show the importance of jet/environment interactions for both radiosource structure and the properties of the surrounding gas. The FR-I observations reveal that the distribution of hot gas determines the radio-lobe morphology, and provide evidence that the subsonic expansion of the lobes heats the surrounding ga...
متن کاملX-ray observations of low-power FR I radio galaxies
According to unified schemes for Active Galactic Nuclei, low-power, Fanaroff-Riley type I (FR I), radio galaxies are thought to be BL Lacs with their jets pointing at relatively large angles with respect to the line of sight. X-ray observations of FR I sources can test this scenario and constrain the presence of obscuring material around the nucleus. In this paper we discuss the X-ray propertie...
متن کاملThe physics of jets in FR I radio galaxies
We model jets in low-luminosity (FR I) radio galaxies as intrinsically symmetrical, axisymmetric, decelerating relativistic flows with transverse velocity gradients. This allows us to derive velocity fields and the three-dimensional distributions of magneticfield ordering and rest-frame emissivity. A conservation-law analysis, combining the kinematic model with X-ray observations of the surroun...
متن کاملFR0CAT: a FIRST catalog of FR 0 radio galaxies
With the aim of exploring the properties of the class of FR 0 radio galaxies, we selected a sample of 108 compact radio sources, called FR0CAT, by combining observations from the NVSS, FIRST, and SDSS surveys. We included in the catalog sources with redshift ≤ 0.05, with a radio size . 5 kpc, and with an optical spectrum characteristic of low-excitation galaxies. Their radio luminosities at 1.4...
متن کاملDust in 3 CR radio galaxies : On the FR 1 – FR 2 difference ⋆
We compare three 3CR samples of 11 FR 1 galaxies, 17 FR 2 galaxies and 18 lobe-dominated quasars contained in the ISO Data Archive. In contrast to the powerful FR 2 galaxies with edge-brightened lobes, the low radio power FR 1 galaxies in our sample do not exhibit any high MIR or FIR dust luminosity, which is typical for a buried, intrinsically more luminous AGN. This consolidates the fact alre...
