BH Mass, Jet and Accretion Disk Connection: An Analysis of Radio-loud and Radio-quiet Quasars

TL;DR

This study investigates the connection between black hole mass, jets, and accretion disks in radio-loud and radio-quiet quasars, revealing that radio-loud fraction increases with broader emission lines and that RL quasars tend to be more luminous with higher black hole masses.

Contribution

It provides new insights into how radio-loud fraction varies with emission line width and suggests intrinsic brightness and black hole mass differences between RL and RQ quasars.

Findings

RL fraction increases with broader emission lines.

RL quasars are more luminous and have higher black hole masses.

Predicted intrinsic brightness and jet connections require further analysis.

Abstract

Surveys have shown radio-loud (RL) quasars constitute $10 \%$-$15 \%$ of the total quasar population. However, it is unknown if the radio-loud fraction (RL quasars/Total quasars) remains consistent among different parameter spaces. This study shows that radio-loud fraction increases for increasing full width half maximum (FWHM) velocity of the H$\beta$ and MgII broad emission line. Our data has been obtained from Shen et al. (2011) catalogue. To investigate the reason, in this preliminary study we analyse various properties like bolometric luminosity, optical continuum luminosity, black hole (BH) mass and accretion rate of RL quasars and RQ quasars sample which have FWHM greater than 15000km/s (High broad line). From the distributions we can conclude for all the properties in high broad line, RL quasars are having higher values than RQ quasars. We have predicted RL quasars are intrinsically brighter than RQ quasars and also predicted BH mass-jet connection and accretion disk-jet connection from our results but to conclude anything more analysis is needed.
