Standardizing reverberation-mapped H$\alpha$ and H$\beta$ active galactic nuclei using radius--luminosity relations involving monochromatic and broad H$\alpha$ luminosities

Shulei Cao, Amit Kumar Mandal, Michal Zajaček +2

We test the standardizability of a homogeneous sample of 41 lower-redshift ($0.00415\le z\le 0.474$) active galactic nuclei (AGNs) reverberation-mapped (RM) using the broad H$\alpha$…
