Revealing the unusual structure of the KAT-7-discovered giant radio galaxy J0133?1302

چکیده

We present a new study of the 1.7 Mpc KAT-7-discovered giant radio galaxy, J0133$-$1302, which was carried out using GMRT data at 323 and 608 MHz. This source is located RA $01^h33^m13^s$ Dec $-13^{\circ}03^\prime00^{\prime\prime}$ has photometric redshift $\sim$0.3. discovered unusual morphological properties include lobes that are exceptionally asymmetric, where upper lobe much further from core when compared to lower lobe, complex structure lobe. hints presence another source, in close proximity edge resembles bent-double, or distorted bent tail (DBT) galaxy. Both have steep spectrum, synchrotron age should be less than about 44 Myr. The an inverted our results suggest parent galaxy J0133$-$1302 starting jet activity. Our spectral analysis indicates this could GigaHertz Peaked Spectrum (GPS)

WNB 0313+683: analysis of a newly discovered giant radio galaxy

We present the results of a detailed analysis of the newly discovered 15′ large radio galaxy WNB 0313+683. It has been discovered in the WENSS and NVSS radio surveys, and has been identified with an optical galaxy at a redshift of 0.0901±0.0002. The linear size of the radio structure is 2.0 Mpc, which places it in the class of Giant Radio Galaxies (GRGs). Radio observations have been carried ou...
