VLT-MUSE spectroscopy of AGNs misclassified by BPT diagnostic or with weak emission lines
Christopher J. Agostino, Samir Salim, Médéric Boquien +3
Despite powerful X-ray emission, some AGNs are known to either lack optical emission lines (so-called 'optically dull' AGNs) or have lines that fall on the star-forming branch of t…
