| contents | <p><strong>CELGs </strong>- Compact emission-line galaxies studied with <strong>S-PLUS </strong>and <strong>4MOST</strong></p> <p>We propose 4MOST/LRS observations of 523 compact emission-line galaxies (<strong>CELGs</strong>), local analogues of high-z star-forming systems that are systematically missed by spectroscopic surveys due to their star-like morphology. Our candidates are selected from S-PLUS imaging, using their strong [OIII] emission at z≈0.3 to overcome this selection bias. This program will build the first large, spectroscopically-confirmed catalogue of this unexplored population. Our primary goals are to:<strong> (1)</strong> secure definitive redshifts; <strong>(2)</strong> characterize ionization sources (star formation vs. AGN) using key diagnostic lines ; and <strong>(3) </strong>determine physical properties, including SFRs, gas-phase metallicities, and stellar masses, to probe the drivers of compact starbursts and their evolutionary role across cosmic time.</p> |
