Three Points?

  • jf225037 by jf225037

    If you invert the image, it seems to have three distinct points. What could have caused this?

    Hi jf225037 and welcome to the Zoo

    The brighter dot in the centre is the core of the galaxy. The two other ones are probably foreground stars from our galaxy.

    Happy hunting !

    Here's an SDSS cutout of the same galaxy (SDSS J140501.03+141520.9):

    And here's the same thing, with what SDSS thinks are separate (photometric) objects (I'll call them "POs"):

    Because they're separate POs, you can put cross-hairs on them easily. Here are the " three distinct points" which I think you're referring to; the first is the nucleus (SDSS J140501.03+141520.9); the second the PO to the E (left), SDSS J140501.42+141518.0; the third the one to the W (right), SDSS J140500.61+141522.8:

    Hope this helps, and happy hunting! 😃
