Interesting object


could be some kind of shock wave (in blue) as this merger takes place

very interesting. would like to see what bands this was captured in

The HSC-DR3 layer show g,r,z bands. The HSC SSP survey observed in g,r,i,z,y, plus some narrow bands.


Very helpful as always - thank you. Was wondering if it was some weird voorwerp but I guess its just a busier star-forming area caused by the merger.

Ah wait I’ve realised I misunderstood. I was wondering if there is a good way to access the individual band exposures for a certain image.

For HSC, no, I’m afraid I don’t have the individual exposures.

You can grab the FITS-format cutout, which will be a 3-D “image cube” – a “g” image, an “r” image, and a “z” image, which you can view in DS9.


thank you very much - very helpful
