ARG000087m - a giant green spiral hosting impressive doublelobes

• by JeanTate

  SDSS J105426.23+573649.1, with SDSS z_ph 0.312±0.0887/0.353±0.1115, would be huge if it were an elliptical; as it's not, its giant size is doubly impressive:

  

  Then there are these rather irregular doublelobes, which we all know spiral galaxies do not possess (NOT!):

  

  And then there's green ... pity we don't have a spectrum. 😦

  Boilerplate: SDSS image per http://skyservice.pha.jhu.edu/DR10/ImgCutout/getjpeg.aspx, FIRST (red) contours derived from the FITS file produced using SkyView with Python code described in this RGZ Talk thread. Image center (J2000.0) is the galaxy SDSS J105426.23+573649.1; "z_ph" its SDSS photometric redshift.

  Very interesting indeed. I've put this source in my list of green sources to follow-up on.

  assuming z~0.31 the radio galaxy is approx 300kpc in size
