The James Webb Space Telescope (JWST) has recently discovered a population of compact red sources at z ≥ 4 known as little red dots (LRDs). They are characterized by their V-shaped continuum spectra and prominent broad Balmer emission lines. As their underlying physical nature remains debated, and direct study at high redshift is challenging, we seek to identify and characterize LRD analogues in the low-redshift universe to constrain their properties and potential evolutionary pathways.
