SGRG-RGB, Red-uGMRT, Green- PanSTARRS, Blue- NVSS
Using our dedicated uGMRT band-3 and band-4 observations we have identified very peculiar S-shaped morphology in a giant radio galaxy (GRG) with the size of 710 kpc. The reason for the peculiar shape may be due to Orbital motion, Precession, Or local environmental effect.
A better explanation of the nature of this unusual object will require further multi-frequency deep radio observations of its core and jets with subarcsecond resolution.
For all the details, please read our research paper:
Discovery of 100 kpc narrow curved twin jet in S-shaped giant radio galaxy: J0644+1043
Our uGMRT maps also revealed a two-sided, wavy, well-collimated, and knotty jet of 100 kpc size. These jets can be considered as “naked jets”, as no diffuse cocoon was detected around them. Moreover, such large jets are rarely observed in GRGs.
We obtained the best possible uGMRT map by combining uGMRT (for the first time) wide band-3 and band-4. The resulting broadband map (300-750 MHz) shows detailed diffuse structures with higher angular resolution.
