Transient

  • CeciliaB by CeciliaB

    I am just curious to know why the blue object to the left of the galaxy is considered a transient.

    It's visible in different surveys (SDSS, DECaLS) made years apart.

    I called 'transient' because I didn't see the blob in the greyscale bands u, g, r of SDSS nor in DECaLS. The color composite images of this galaxy from these surveys are pixelated and less deep than KIDS. No record shows up in KIDS catalog Or SDSS. I could be wrong...

    We need a deeper coming survey like LSST for a convincing answer.
