Double Dust?

  • metalmania by metalmania

    I'm assuming this won't count as double dust because a) it looks like a spiral galaxy to me and b) it looks disturbed - especially at the l/h where the dustlane goes off at 45 degrees...just double (dust) checking.

    Add it anyway! I will be going through all the candidates at a later stage to remove the ones that don't meet the criteria.

    As for the angle of dustlane, it is following the disk of the galaxy. Nice!

    Here is the SDSS image for those interested. Very unusual dustlane!

    Here's how the dustlanes appear in SDSS:

    It certainly looks disturbed, doesn't it? The two faint 'polar' blobs ('above' and 'below' the nucleus) seem real, but not EELRs (extended emission line regions, sorta voorwerpjes), so may be the remnants of a merger/interaction, rather than gas 'lit up' by an AGN. Interestingly, the automated SDSS spectrum pipeline classifies this (or rather its inner bulge/nucleus) as "galaxy starforming broadline", so perhaps the dust has turned a bluish nucleus (due to starformation) yellow?

    Thanks both...I didn't even notice those blueish polar blobs!...weird.
