Abstract:
We have recently completed a 64-night spectroscopic monitoring
campaign at the Lick Observatory 3m Shane telescope with the aim of
measuring the masses of the black holes in 12 nearby (z<0.05) Seyfert
1 galaxies with expected masses in the range ∼106-107M☉ and
also the well-studied nearby active galactic nucleus (AGN) NGC 5548.
Nine of the objects in the sample (including NGC 5548) showed optical
variability of sufficient strength during the monitoring campaign to
allow for a time lag to be measured between the continuum fluctuations
and the response to these fluctuations in the broad Hβ emission,
which we have previously reported. We present here the light curves
for the Hα, Hγ, HeIIλ4686, and HeIλ5876
emission lines and the time lags for the emission-line responses
relative to changes in the continuum flux.
Description:
The spectroscopic monitoring was carried out over 64 nights at the
Lick Observatory 3m Shane telescope between 2008 March 25 and June 1.
The red CCD of the Kast dual spectrograph was employed with the 600
lines/mm grating (resulting in spectral coverage over 4300-7100Å),
giving a nominal resolution of 2.35Å/pixel in the dispersion
direction and 0.78"/pixel in the spatial direction. Table 1 lists the
nine LAMP (Lick AGN Monitoring Program) targets for which we were able
to measure Hβ time lags. Emission-line light curves for the nine
LAMP AGNs are presented in Tables 3-11.
