Rather curious case .. could this be a remnant from a lobe? with the source not on this picture?
Or this is an artifact?Posted

Thanks! If i got it right, it somehow connected with that bright radio source on the picture?

Hmm.. that's a curious find! I don't think the radio source is connected to the bright infrared source to the left at all. The radio structure extends to the bottom right side as the visible radio pattern goes (have checked with larger view FIRST survey data). That's definitely not an artifact; it's as you guessed a relic lobe most likely. And what that means it may be a dead radio galaxy - sort of radio galaxy relic fading away and which jets switched off! I'll be really excited if it's gets confirmed!! First thing to check up tomorrow morning for me (it's late night here 😉 ).

This is getting suspicious, maybe we are looking at some sort of RFI? or ghost?

Whoa! Slow down folks! The original image here is an artifact. The only way to tell is to look at a much larger field, which I did using the NVSS at lower resolution. You can see the larger field at http://umn.edu/~larry/RGZ/ARG0000vjq.jpg . I'm going to see if there's some way we can do this automatically.
