4 panels showing various fundamental plane fits with data that mostly disagree.

High-Eddington Rate IMBHs Do Not Fall on the Fundamental Plane

Two by two panels. Left two panels show blocky, pixelated image of indistinct pattern peaking at the center and a line spanning approximately two pixels and labeled "1 arcsec". The right two panels show a much finer resolution version of the same with a black x and a black square at the center of the peaked distribution. The top panel has an arc-like shape in the upper right, the bottom has the same shape in the lower left.

Low-mass dual candidate is lone black hole

Figure showing log of flux density in Jy as a function of log of frequency in MHz. The y-axis ranges from -4 to 1. The x-axis ranges from 3.0 to 4.75. The data from x = 3.0 to 3.505 are flat at about y = 0. The data from x = 3.505 to 4.6 are going down. The legend indicates that the source is IC 1459, that the low-frequency spectral index is -0.08 +/- 0.08, the high-frequency spectral index is 0.73 +/- 0.01, and the log of the turnover frequency is 3.55 +/- 0.022.

Turnover Frequency

Three-dimensional view of fundamental plane of black hole accretion. A cube is labeled with the following orthogonal axes and limits. X-axis: Radio [erg/s] 30–45; Y-axis: X-ray [erg/s] 30–45; Z-axis: Mass [solar] 0–15. A light blue plane cuts through data points which are clustered as red spheres at the high-mass end and blue cubes and cones at the low mass end.

Measuring black hole masses with X-ray and Radio observations

Figure with y-axis as flux density ranging from about 1.5e-14 to 5e-14 erg / s / cm^2 / angstrom and x-axis is time (MJD - 50000) from about 6300 to 6550. There are three sets of points, red, black, and blue with error bars. the prevailing trend from left to right is flat and then increasing.
