SDSS J122524.51+072735.1 , the SIMBAD biblio

As both a test and demonstration of the power of the Legacy Survey of Space and Time (LSST) data for this purpose, we present a set of 5 candidate active galactic nucleus-ionized extended emission-line regions in the Rubin Virgo field, based on visual color selection. Although still pending spectroscopic confirmation, these illustrate the depth of detection of the LSST data compared to existing broadband surveys, even for these irregularly shaped objects with almost pure emission spectra.
