Sources are compiled from archival data of both radio-loud and radio-quiet quasars over redshifts $0.1 < z < 5.0$ to produce a sample of 353 sources with known X-ray, radio, and black hole mass measurements. A fundamental plane of accretion activity is fit to a sample of radio-loud and radio-quiet quasars, and we find a dichotomy between radio-loud and radio-quiet sources. The set of best-fit equations that best describe the two samples are $\\log{L_{R}} = (1.12 \\pm 0.06) \\log{L_{X}} - (0.20 \\pm 0.07) \\log{M} -(5.64 \\pm 2.99)$ for our radio-loud sample and $\\log{L_{R}} = (0.48 \\pm 0.06) \\log{L_{X}} + (0.50 \\pm 0.08) \\log{M} + (15.26 \\pm 2.66)$ for our radio-quiet sample. Our results suggest that the average radio-quiet quasar emission is consistent with advection dominated accretion, while a combination of jet and disc emission dominates in radio-loud quasars. We additionally examine redshift trends amongst the radio-loud and radio-quiet samples, and we observe a redshift dependence for the fundamental plane of radio-loud quasars. Lastly, we utilize the fundamental plane as a black hole mass estimation method and determine it useful in studying systems where standard spectral modeling techniques are not viable.", "revisions": [ { "version": "v1", "updated": "2022-01-12T19:43:00.000Z" } ], "analyses": { "keywords": [ "fundamental plane", "black hole activity", "black hole mass estimation method", "average radio-quiet quasar emission", "radio-loud quasars" ], "note": { "typesetting": "TeX", "pages": 9, "language": "en", "license": "arXiv", "status": "editable" } } }
