Arp 77 (NGC 1097) Star Jets

Technical card

Resolution: 2025x2230

Astrometry.net job: 775709

Description

My image of NGC 1097 (aka Arp 77) already was posted. Details of the imaging set-up, acquisition, and processing can be seen in that posting. This image was reprocessed using a PixInsight script for enhancing long wavelets. The reprocessing targeted revealing the two jets indicated on the image.
These jets are not plasma jets, but jets of stars presumably ejected from NGC 1097, for reasons unknown but hypothesized to be due to an ancient collision with another galaxy. These are the two brighest of 4 identified jets.
That these jets are at all visible on the low-integration time of this image (L~1 hr) speaks to their brightness. I understand they are the most visible of any such jets known.
