Locations of five LRD analogues in BPT/VO diagrams (Baldwin et al. 1981; Veilleux & Osterbrock 1987) with black solid and blue dashed demarcation lines (Kewley et al. 2001, 2006; Kauffmann et al. 2003). Our sample objects are shown as red stars. For comparison, we show high-redshift LRDs from Matthee et al. (2024) as orange circles. We also show the Rosetta Stone at z = 2.26 (green pentagon; Juodžbalis et al. 2024) and a previously identified local LRD at z = 0.1 (brown square; Ji et al. 2026).
