ARG0003s69

  • Dolorous_Edd by Dolorous_Edd

    Found it in antikodon's collection

    DSS 2 Red 1' x 1'

    Clearly an Eos

    It is 2MASX 03294952-2850581 aka FGCE 0328

    Also it is visible in all 4 WISE bands

    How real the radio emission from it?

    Radio emission is clearly goes beyond optical galaxy, but is it by-product of survey resolution? and in reality it is smaller?

    My guess that if it was VLA FIRST map, we would have seen a small compact source

    And perhaps another one

    2MASX J03323506-2755331 aka SARS 052.62317-28.09389

    Some contour overlay images might help ...

    In the left hand column, the background image is the ATLAS image (plus contours) from ARG0003s69, from a screenshot.

    In the right hand column, the background image is a SWIRE cutout, using the SWIRE cutout service (default is JPEG, inverted).

    In the top row, NVSS contours (in cyan) are overlaid.

    In the bottom row, contours derived from WISE band 1 (3.4μ, magenta) are overlaid.

    I think these four images - together with the ARG field (ATLAS contours on SWIRE image) - are quite informative. Let's discuss.

    The images in this post were created from sources, and using methods, described in this RGZ Talk post. The image is centered at (RA, Dec) = (52.449, -28.852)

    UPDATE: well, may there never be a day when you don't learn something new! Despite what my Python program writes onto the images, they're actually 400x400 pix! 😮 😮 😮 Oh the joys of quirks of programming languages! I found the problem, have fixed it, and will re-do the erroneous images (they'll look almost exactly the same; it's a scaling thing, not a truncation or anything nasty like that).

    Same layout as in my previous post (yes, the scale bar is white in the right hand column! 😦):

    Rather than replace the, um, errant images, I will post the corrected ones separately (I'm not a fan of revisionism, and Talk makes that ridiculously easy).

    Hello, I am new to this and do not have an astronomy background. Can anyone explain to me what is happening in this image in laymen's terms? Thank you.
