The Seoul National University AGN Monitoring Project. II. BLR Size and Black Hole Mass of Two AGNs
Active galactic nuclei (AGNs) show a correlation between the size of the broad line region and the monochromatic continuum luminosity at 5100 Å, allowing black hole mass estimation based on single-epoch spectra. However, the validity of the correlation is yet to be clearly tested for high-luminosity AGNs. We present the first reverberation mapping results of the Seoul National University AGN Monitoring Project (SAMP), which is designed to focus on luminous AGNs for probing the high end of the size–luminosity relation. We report time lag measurements of two AGNs, namely, 2MASS J10261389+5237510 and SDSS J161911.24+501109.2, using the light curves obtained over an ∼1000 days period with an average cadence of 10 and 20 days, respectively, for photometry and spectroscopy monitoring. Based on a cross-correlation analysis and Hβ line width measurements, we determine the Hβ lag as and days in the observed frame, and black hole mass as and , respectively, for 2MASS J1026 and SDSS J1619

Based on a cross-correlation analysis and Hβ line width measurements, we determine the Hβ lag as {41.8}-6.0+4.9 and {52.6}-14.7+17.6 days in the observed frame, and black hole mass as {3.65}-0.57+0.49× {10}7{M}ȯ and {23.02}-6.56+7.81× {10}7{M}ȯ , respectively, for 2MASS J1026 and SDSS J1619.</p

The Seoul National University AGN Monitoring Project. II. BLR Size and Black Hole Mass of Two AGNs
Active galactic nuclei (AGNs) show a correlation between the size of the
broad line region (BLR) and the monochromatic continuum luminosity at 5100 \AA,
allowing black hole mass estimation based on single-epoch spectra. However, the
validity of the correlation is yet to be clearly tested for high-luminosity
AGNs. We present the first reverberation-mapping results of the Seoul National
University AGN monitoring program (SAMP), which is designed to focus on
luminous AGNs for probing the high end of the size-luminosity relation. We
report time lag measurements of two AGNs, namely, 2MASS J10261389+5237510 and
SDSS J161911.24+501109.2, using the light curves obtained over a 1000 day
period with an average cadence of 10 and 20 days, respectively for
photometry and spectroscopy monitoring. Based on a cross-correlation analysis
and H line width measurements, we determine the H lag as
and days in the observed-frame, and
black hole mass as and
, respectively for 2MASS J1026 and
SDSS J1619
