J1649+26: A Grand-Design Spiral with a Large Double-Lobed Radio Source - Mao et al.

  • JeanTate by JeanTate

    It appeared earlier today in arXiv, as arXiv:1410.8520. Perhaps the best part about it is this, under Comments: "Accepted for publication in MNRAS". Yay! 😃

    The paper is mentioned in another thread here in the Journal Club, and also the SDSS image posted (with and without contour overlays) in the Hourglass sources associated with spiral galaxies thread (page 8 ).

    Nice discussion there. The paper has several mentions of Radio Galaxy Zoo - we're hoping that the spirals Zooites have been discovering will help prod the studies of these objects as a population, rather than as unique/individual objects.

    Hello!

    Yes that is the plan! JeanTate et al. are doing an awesome work on identifying spiral DRAGNs and now that the J1649+2635 paper is out of the way I am hoping to spend more time with RGZ-ites 😄

    thanks all!

    This galaxy shows up in following new paper (image on page 4), but it is presented as a re-discovery!:

    Discovery of rare double-lobe radio galaxies hosted in spiral galaxies

    Double-lobe radio galaxies in the local Universe have traditionally been found to be hosted in elliptical or lenticular galaxies. We report the discovery of four spiral-host double-lobe radio galaxies (J0836+0532, J1159+5820, J1352+3126 and J1649+2635) that are discovered by cross-matching a large sample of 187005 spiral galaxies from SDSS DR7 to the full catalogues of FIRST and NVSS. J0836+0532 is reported for the first time.

    PS: I wonder, why J0836+0532 was missed by Mao et al.?

    J1649+26: A Grand-Design Spiral with a Large Double-Lobed Radio Source- Mao et al.

    The resulting catalogue contained three sources that were identified as spiral galaxies in the “superclean” sample from Galaxy Zoo, and had extended radio emission with ...One was a chance-alignment and another was a nearby star-forming galaxy. The third galaxy, SDSS J164924.01+263502.5 (henceforth J1649+2635), hosts a powerful, double-lobed radio source and is the subject of this paper!

    I would like to know the SDSS Object-IDs of the chance-alignment and the star-forming galaxy!
