Abstract:
Mass accretion rates in dimensionless and physical units, and
efficiency factors describing the total radiant luminosity of the disc
and the beam power of the outflow are obtained and studied here for
samples of black hole systems with outflows. Four samples of sources
including 576 LINERs, 100 classical double (FRII) radio sources, 80
relatively local AGN, and 103 measurements of four stellar mass X-ray
binary systems, referred to as Galactic Black Holes (GBHs), are
included in the study. All of the sources have highly collimated
outflows leading to compact radio emission or powerful extended (FRII)
radio emission. The properties of each of the full samples are
explored, as are those of the four individual GBH, and sub-types of
the FRII and local AGN samples. Source types and sub-types that have
high, medium, and low values of accretion rates and efficiency factors
are identified and studied. A new efficiency factor that describes the
relative impact of black hole spin and mass accretion rate on the beam
power is defined and studied, and is found to provide a new and
interesting diagnostic. Mass accretion rates for 13 sources and
efficiency factors for 6 sources are compared with values obtained
independently, and indicate that similar values are obtained with
independent methods. The mass accretion rates and efficiency factors
obtained here substantially increase the number of values available,
and improve our understanding of their relationship to source types.
The redshift dependence of quantities is presented and the impact on
the results is discussed.
Description:
Four samples are considered here. The samples include 576 LINERs from
Nisbet & Best (2016MNRAS.455.2551N 2016MNRAS.455.2551N, Cat. J/MNRAS/455/2551) (hereafter
NB16); 100 classical double (FRII) sources from Daly
(2016MNRAS.458L..24D 2016MNRAS.458L..24D) (D16) and Daly (2019ApJ...886...37D 2019ApJ...886...37D) (D19); 80
local AGN that are compact radio sources from Merloni et al.
(2003MNRAS.345.1057M 2003MNRAS.345.1057M) (hereafter M03); and 103 observations of four
stellar-mass Galactic Black Hole systems (GBH) that are in X-ray
binary systems. The stellar-mass GBH data includes the 102
observations listed in table 2 of D19 plus one observation of A0 6200
discussed in section 5 of D19. These are stellar mass X-ray binaries,
and each of the GBH have multiple simultaneous radio and X-ray
observations (Saikia et al. 2015MNRAS.450.2317S 2015MNRAS.450.2317S). These four samples
were studied by D19 who reported spin functions, spin values, and
accretion disc magnetic field strengths in dimensionless and physical
units for each source and observation.
Here, the dimensionless disc magnetic field strength, that is, the
ratio of the accretion disc field strength to the Eddington magnetic
field strength, is used to obtain the mass accretion rate in
dimensionless and physical units for each system and for each
observation of the GBH.

Global Notes:
Note (G1): The dimensionless mass accretion rate of each source can be
empirically determined, using the results obtained by
Daly (2019ApJ...886...37D 2019ApJ...886...37D) who showed that the dimensionless mass
accretion rate dm/dt=(B/BEdd)2, where B is the strength of the
magnetic field anchored in the accretion disc and
BEdd∝Mdyn-1/2 is the Eddington magnetic field strength
Note (G2): The mass accretion rate in physical units dM/dt can be obtained from
dm/dt and dM/dt=dm/dt(LEdd/c2)=(B/BEdd)2(LEdd/c2)
Note (G3): The efficiency factor of the accretion disc, εbol, is
defined as εbol=Lbol/(c2dM/dt)
Note (G4): The efficiency factor of the outflow, εj, is defined as
εj=Lj/(c2dM/dt), where Lj is the beam power of the
outflow
Note (G5): This efficiency factor εs/d is defined as
εs/d=F2(dm/dt), where F2 is the normalized spin
function
