Constraining the X-ray reflection in low accretion-rate active galactic nuclei using <i>XMM-Newton</i>, NuSTAR, and <i>Swift</i>

An interesting feature in active galactic nuclei (AGN) accreting at low rate is the weakness of reflection features their X-ray spectra, which can result from gradual disappearance torus with decreasing accretion rates. It has been suggested that luminosity AGN (LLAGN) would have a different reflector configuration compared high AGN, either covering smaller fraction sky or simply having less material. Additionally, we note determination spectral index ($\Gamma$) and cut-off energy primary power-law emission affected by inclusion models, showing importance using them to study mechanism, especially case LLAGN previously shown dispersion on relation between $\Gamma$ rate. Our purpose constrain geometry column density sample broad range combining data XMM-Newton + NuSTAR Swift hard X-ray-flux limited 17 BASS/DR2 rates $\lambda_{Edd}$=L$_{\rm Bol}$/L$_{\rm Edd}$<10$^{-3}$. We fit all spectra model for (borus02) disk (Xillver) reflectors. found tentative correlation rate, shows lower high-luminosity objects. also confirm $\lambda_{Edd}$, scatter than reported, thanks high-energy models. results are consistent break $\lambda_{Edd}\sim10^{-3}$, suggestive mechanism higher AGN.
