چکیده

We present for the first time a study of peculiar giant radio galaxy (GRG) J223301+131502 using deep multi-frequency observations from GMRT (323, 612, and 1300 MHz) LOFAR (144 along with optical spectroscopic WHT~4.2m telescope. Our have firmly established its redshift 0.09956 unveiled exceptional jet structure extending more than $\sim$ 200 kpc leading to kink 100 kpc. measure overall size this GRG be 1.83 Mpc; it exhibits lobes without any prominent hotspots closely resembles barbell. low-frequency maps clearly reveal steep-spectrum diffuse emission GRG. The magnetic field strength 5 $\mu$G spectral ages between about 110 mega years were estimated data 144 MHz 323 612 observations. discuss possible causes formation observed feature GRG, which includes precession axis, development instabilities reconnection. Despite enormous size, Barbell is found residing in low-mass (M$_{200} \sim 10^{14}$ $\rm M_{\odot}$) cluster.

A Parsec Scale Accelerating Radio Jet in the Giant Radio Galaxy NGC 315

Observations of the core of the giant radio galaxy NGC315 made with VLBI interferometers are discussed in the context of a relativistic jet. The sidedness asymmetry suggests Doppler favoritism from a relativistic jet. The presence of moving features in the jet as well as jet counter–jet brightness ratios hint at an accelerating, relativistic jet. An increasing jet velocity is also supported by ...

A giant radio jet ejected by an ultramassive black hole in a single - lobed radio galaxy

We report the discovery of a very unusual, highly asymmetric radio galaxy whose radio jet, the largest yet detected, emits strongly polarized synchrotron radiation and can be traced all the way from the galactic nucleus to the hot spot located ∼ 440 kpc away. This jet emanates from an extremely massive black-hole (> 109M⊙) and forms a strikingly compact radio lobe. No radio lobe is detected on ...

Radio jet interactions in the radio galaxy PKS 2152 - 699

We present radio observations of the radio galaxy PKS 2152-699 obtained with the Australia Telescope Compact Array (ATCA). The much higher resolution and s/n of the new radio maps reveals the presence of a bright radio component about 10 arcsec NE of the nucleus. This lies close to the highly ionized cloud previously studied in the optical and here shown in a broadband red snapshot image with t...

Three episodes of jet activity in the FRII radio galaxy

We present Very Large Array images of a “Double-Double Radio Galaxy”, a class of objects in which two pairs of lobes are aligned either side of the nucleus. In this object, B0925+420, we discover a third pair of lobes, close to the core and again in alignment with the other lobes. This first-known “Triple-Double” object strongly increases the likelihood that these lobes represent mutiple episod...
