A strong negative correlation between radio loudness $R_{\mathrm{UV}}$ and optical-to-X-ray spectral index ${\alpha }_{\mathrm{ox}}$ in low-luminosity AGNs

Shuang-Liang Li, Fu-Guo Xie

It has been argued for years that the accretion mode changes from bright active galactic nuclei (AGNs) to low-luminosity AGNs (LLAGNs) at a rough dividing point of bolometric Eddin…
