Starforming area or pea?

  • Ghost_Sheep_SWR by Ghost_Sheep_SWR

    The spectrum of the bright blue object near the center seems exactly like that of a pea. It has the same z as the spiral.

    Is it a very active starforming area or might it actually be a pea? ( or both phenomenon generate equal spectra)

    NED reference http://ned.ipac.caltech.edu/cgi-bin/ex_refcode?refcode=2010MNRAS.403..896P suggests

    "The scatter and shift of the SDSS HII regions in the t2,O-t3,O diagram can be understood if they are composite nebulae excited by two or more ionizing sources of different temperatures"
