The supermassive black hole at the core of Messier 87, here shown by an image by the Event Horizon Telescope, is among the black holes in this list.

This is an ordered list of the most massive black holes so far discovered (and probable candidates), measured in units of solar masses (M☉), approximately 2×1030 kilograms.

Introduction

Comparisons of large and small black holes in galaxy OJ 287 to the Solar System

A supermassive black hole (SMBH) is an extremely large black hole, on the order of hundreds of thousands to billions of solar masses (M☉), and is theorized to exist in the center of almost all massive galaxies. In some galaxies, there are even binary systems of supermassive black holes, see the OJ 287 system. Unambiguous dynamical evidence for SMBHs exists only in a handful of galaxies;[1] these include the Milky Way, the Local Group galaxies M31 and M32, and a few galaxies beyond the Local Group, e.g. NGC 4395. In these galaxies, the mean square (or root mean square) velocities of the stars or gas rises as ~1/r near the center, indicating a central point mass. In all other galaxies observed to date, the rms velocities are flat, or even falling, toward the center, making it impossible to state with certainty that a supermassive black hole is present.[1] Nevertheless, it is commonly accepted that the center of nearly every galaxy contains a supermassive black hole.[2] The reason for this assumption is the M–sigma relation, a tight (low scatter) relation between the mass of the hole in the ~10 galaxies with secure detections, and the velocity dispersion of the stars in the bulges of those galaxies.[3] This correlation, although based on just a handful of galaxies, suggests to many astronomers a strong connection between the formation of the black hole and the galaxy itself.[2]

Although SMBHs are currently theorized to exist in almost all massive galaxies, more massive black holes are rare; with only fewer than several dozen having been discovered to date. There is extreme difficulty in determining the mass of a particular SMBH, and so they still remain in the field of open research. SMBHs with accurate masses are limited only to galaxies within the Laniakea Supercluster and to active galactic nuclei.

Another problem for this list is the method used in determining the mass. Such methods, such as broad emission-line reverberation mapping (BLRM), Doppler measurements, velocity dispersion, and the aforementioned M–sigma relation have not yet been well established. Most of the time, the masses derived from the given methods contradict each other's values.

This list contains supermassive black holes with known masses, determined at least to the order of magnitude. Some objects in this list have two citations, like 3C 273; one from Bradley M. Peterson et al. using the BLRM method,[4] and the other from Charles Nelson using [OIII]λ5007 value and velocity dispersion.[5] Note that this list is very far from complete, as the Sloan Digital Sky Survey (SDSS) alone detected 200000 quasars, which likely may be the homes of billion-solar-mass black holes. In addition, there are several hundred citations for black hole measurements not yet included on this list. Despite this, the majority of well-known black holes above 1 billion M☉ are shown. Messier galaxies with precisely known black holes are all included.

New discoveries suggest that many black holes, dubbed 'stupendously large', may exceed 100 billion or even 1 trillion solar masses.[6]

List

This list is incomplete; you can help by adding missing items. (June 2017)

Due to the very large numbers involved, listed black holes here have their mass values in scientific notation (numbers multiplied to powers of 10). Values with uncertainties are written in parentheses when possible. Note that different entries in this list have different methods and systematics in obtaining their mass values, and hence different levels of confidence in their masses. These methods are specified in their notes.

List of most massive black holes
Host or black hole name Solar mass
(Sun = 1 × 100) 		Notes
(Theoretical limit) 2.7×1011 This is the maximum mass of a black hole that models predict, at least for luminous accreting SMBH's. At around 1010 M☉, effects of both intense radiation and star formation in the accretion disc slow down black hole growth. Given the age of the universe and the composition of available matter, there is simply not enough time to grow black holes larger than this mass.

The limit is only 5×1010 M☉ for black holes with typical properties, but can reach 2.7×1011 M☉ at maximal prograde spin (a = 1).[7][8][9][10] Reported for reference.

Phoenix A 1×1011[11] Estimated using a calorimetric model on the adiabatic behavior of core regrowth and an assumed core-Sérsic model of n=4. It is consistent with evolutionary modelling of gas accretion and the dynamics and density profiles of the galaxy.[11] Mass has not been measured directly.

Another recent estimate gives ~1.26×1010,[12] though this is still uncertain due to low resolution of X-ray/MIR data.

TON 618 4.07×1010[13] Estimated from quasar C IV line correlation. An older estimate gives a mass of 6.6×1010M☉ based on the quasar Hβ emission line correlation.[14]
Holmberg 15A (4.0±0.8)×1010[15] Mass specified obtained through orbit-based, axisymmetric Schwarzschild models. Earlier estimates range from ~310 billion M☉ down to 3 billion M☉, all relying on empirical scaling relations and are thus obtained from extrapolation and not from kinematical measurements.[16]
IC 1101 (4–10)×1010[17] Estimated from properties of the host galaxy (Faber–Jackson relation); mass has not been measured directly.
S5 0014+81 4×1010[18][19][20] A 2010 paper suggested that a funnel collimates the radiation around the jet axis, creating an optical illusion of very high brightness, and thus a possible overestimation of the black hole mass.[18]
SMSS J215728.21-360215.1 (3.4±0.6)×1010[21] Estimated using near-infrared spectroscopic measurements of the MgII emission line doublet.
SDSS J102325.31+514251.0 3.31+0.67
−0.56×1010[22]		 Estimated from quasar MgII emission line correlation.
Abell 1201 BCG (3.27±0.71)×1010[23] Estimated using strong gravitational lensing from a distant galaxy 1.3 arcseconds separated from the nucleus of the BCG. Earlier estimates suggest a mass of 1.3×1010 M☉.[24] Beware of ambiguity between the BH mass determination and the galaxy cluster's dark matter profile.[25]
H1821+643 3×1010[26] Value obtained as an indirect estimate using a model of minimum Eddington luminosity required to account for the Compton cooling of the surrounding cluster.[26]

2MASS J13260399+7023462 (2.7±0.4)×1010[29] Estimated using the full-width half maxima of the CIV emission line and monochromatic luminosity at 1350 Å wavelength.

1.0+0.17
−0.13×1010[31]		 Based on velocity width of CO line from orbiting molecular gas,[30] and reverberation mapping using SiIV and CIV emission lines.[31]

SDSS J074521.78+734336.1 (1.95±0.05)×1010[22] Estimated from quasar MgII emission line correlation.
OJ 287 primary 1.8×1010[34] A smaller 100 million M☉ black hole orbits this one in a 12-year period (see OJ 287 secondary below). But this measurement is in question[by whom?] due to the limited number and precision of observed companion orbits.
NGC 1600 (1.7±0.15)×1010[35][36] Unprecedentedly massive in relation of its location: an elliptical galaxy host in a sparse environment.
