Barbell GRG
Barbell GRG: I spotted this giant object with peculiar morphology in NVSS 1.4 GHz radio survey sometime in 2014 during my M.Sc thesis work. This gave me a chance to write one of my first GMRT proposals or first telescope proposal ever! The first image with GMRT at 610 MHz revealed the long-collimated bipolar jets and more importantly resolved the mystery of a big radio blob sitting near the middle of the source (seen in a coarser NVSS image). The ~5 arcsec sensitive map unveiled a giant kink in the jet which can fit nearly 3 Milkyway galaxies. We produced the 610 MHz GMRT image just before going to the big jets conference at ICTS in Oct 2015, where all the big names in the field of extragalactic radio jets had gathered (e.g. Blandord, Readhead, Laing, and Fanroff etc). In the same meeting, things turned more interesting when we showed it to Katherine Blundell, who then took it to Roger Blandford and both look astonished. Roger Blandford even showed it in his conference summary talk. It was quite joyous for the aspiring PhD student in me. I never thought it would take me another 7 years to publish it! I also suspect my RPL labmates grew tired of seeing its images on my desk. ;)
Over years, we had carry out multiple observations with GMRT, LoFAR and W Herschel optical telescope to get (nearly) the whole picture.
The name 'Barbell'- In early 2019 Prof Saikia was writing an article on jets in Resonance, and asked me if I could share the image of this object. When I shared the image, he asked me does it have a name (since we had not published it then) and after hours of staring at the source, it occurred to me that it looks like a weight lifting equipment in the gym (not that I am a gym person) - Barbell! Also, it sounds way better than GRG-J2233+1315 :P
Apart from being nearly a 2 Mpc big giant radio galaxy with one of the longest collimated jets and kink, it is also a bright cluster galaxy, residing in a dense environment.
