Abstract

Recently, Rakshit et al. (Astrophys. J. 869:173, 2018) reported the discovery of SDSS J103024.95+ 551622.7, a radio-loud narrow-line Seyfert 1 galaxy having a ∼ 100 kpc scale double-lobed radio structure. Here we analyse archival radio interferometric imaging data taken with the Very Large Array (VLA) at 5 GHz, and with the Very Long Baseline Array (VLBA) at 4.3 and 7.6 GHz. Two hotspots and a compact core are detected with the VLA at arcsec scale, while a single milliarcsec-scale compact radio core is seen with the highest resolution VLBA observations. The Fermi Large Area Telescope did not detect γ-ray emission at the position of this source. In the mid-infrared, the Wide-field Infrared Survey Explorer satellite light curve, covering more than 7 years and including the most recent data points, hints on flux density variability at 3.4 μm. Our findings support the notion that this source is a young version of Fanaroff–Riley type II radio galaxies.
