Radio images of SDSS J1105+1452. The colour scale shows the 1.4-GHz FIRST image (White et al. 1997). The grey circle shows the restoring beam of the FIRST image in the lower left corner. The white contours represent the 3-GHz VLASS SE image taken on August 18 2020. The peak intensity is 38.7 mJy beam−1. The lowest contours are drawn at ±0.4 mJy beam−1 (corresponding to a 3σ image noise level); further contours increase by a factor of two. The restoring beam of the VLASS SE image is shown as a white ellipse in the lower right corner. Its FWHM size is
. The major axis of the position angle is 29°. The VLASS and FIRST radio emission is consistent with a point source and no extended jet structure is detected. Further, no other bright radio sources that could have affected the radio measurements are in the surrounding field. The black cross marks the Gaia DR3 optical position (Gaia Collaboration 2023).
