AGN?

• by tomas_depaula

  Hello everyone!

  Is this a galaxy with an active nucleus?

  Hi tomas_depaula,

  My 2 cents: it has a very bright nucleus and designations as Infrared Source and Ültraviolet Source which seems to indicate 'yes'. But I can not find any references in NED for AGN, and only 1 for 'candidate AGN' in VizieR.

  Looking at the images from WISE it is only visible in bands W1 and W2, whereas all AGN (Active Galactic Nucleus) I have encountered are usually W1>W2>W3>W4. So based on that last observation I go for 'no'.

  Here you can see the images for yourself (it is in different Infrared wavelengths): WISE POSITION COLOR + BANDS

  Love to hear from others though.

  Have fun!

  My 2 pence 😃 AGN are green or magenta, depending on distance.

  My 2 Florin 😉 or invisible, the number of (IR) AGN's without an optical counterpart I've encountered so far are near infinite 😕

  Voorwerp search -> love AGN

  Brown Dwarf search -> hate AGN
