Abstract:
This paper reports results of the third-year campaign of monitoring
super-Eddington accreting massive black holes (SEAMBHs) in active
galactic nuclei (AGNs) between 2014 and 2015. Ten new targets were
selected from the quasar sample of the Sloan Digital Sky Survey
(SDSS), which have generally been more luminous than the SEAMBH
candidates in the last two years. Hβ lags (τHβ) in
five of the 10 quasars have been successfully measured in this
monitoring season. We find that the lags are generally shorter, by
large factors, than those of objects with same optical luminosity, in
light of the well-known RHβ-L5100 relation. The five quasars
have dimensionless accretion rates of dM/dt=10-103. Combining these
with measurements of the previous SEAMBHs, we find that the reduction
of Hβ lags depends tightly on accretion rates,
τHβ/τR-L∝(dM/dt)-0.42, where τR-L is
the Hβ lag from the normal RHβ-L5100 relation. Fitting
63 mapped AGNs, we present a new scaling relation for the broad-line
region: RHβ=α1l44β1min
[1,(dM/dt)/(dM/dt)c)-γ1], where l44=L5100/1044erg/s is
the 5100Å continuum luminosity, and the coefficients are
α1=29.6-2.8+2.7 lt-day, β1=0.56-0.03+0.03,
γ1=0.52-0.16+0.33, and (dM/dt)c=11.19-6.22+2.29. This
relation is applicable to AGNs over a wide range of accretion rates,
from 10-3 to 103. Implications of this new relation are briefly
discussed.
Description:
The super-Eddington accreting massive black hole (SEAMBH) project uses
the Lijiang 2.4m telescope, operated by Yunnan Observatories. We
adopted the same observational procedures described in detail in
PaperI (Du et al. 2014, J/ApJ/782/45). Observational results of the
three years spectroscopic monitoring (2012-2014) are listed in table1.

Note (1): We marked the time lag of J080131 as "uncertain" in Paper IV
(Du+, 2015, J/ApJ/806/22), but we pick it up here because its lag
reported in Paper IV is highly consistent with the number measured
in the present paper.

b = MCG+06-26-012 was selected as a super-Eddington candidate in SEAMBH2012

we discard it here (no Hβ reverberations data for this object).
