Pigeon of the Week: 4

"Salvation.jpeg".png

One of the most interesting PIG’s may not be a PIG at all. This stripe looks very much like a galaxy thats close by but it does not appear in the image taken by Hubble Space Telescope whatsoever. This could be due to a low continuum with very bright emission lines that means only MUSE can see it. When we searched for a particular wavelength that this was particularly bright at we found nothing which ruled out the emission theory. We were inclined to believe it was just an imaging error or some very unlikely noise pattern until SExtractor (our automatic  searching script) also decided it could be a source. This PIG is going to need more investigation…Screen Shot 2018-07-24 at 11.24.56.png~Will
