Abstract:
We present the results from a detailed analysis of photometric and
spectrophotometric data on five Seyfert 1 galaxies observed as a part
of a recent reverberation mapping program. The data were collected at
several observatories over a 140 day span beginning in 2010 August and
ending in 2011 January. We obtained high sampling-rate light curves
for Mrk 335, Mrk 1501, 3C 120, Mrk 6, and PG 2130+099, from which we
have measured the time lag between variations in the 5100 Å
continuum and the Hβ broad emission line. We then used these
measurements to calculate the mass of the supermassive black hole at
the center of each of these galaxies. Our new measurements
substantially improve previous measurements of MBH and the size of
the broad line-emitting region for four sources and add a measurement
for one new object. Our new measurements are consistent with
photoionization physics regulating the location of the broad line
region in active galactic nuclei.
Description:
The majority of the spectra were obtained using the MDM Observatory
1.3 m McGraw-Hill telescope on Kitt Peak. We used the Boller and
Chivens CCD spectrograph to obtain spectra over the course of 120 nights
from 2010 August 31 to December 28. We used the 350 mm-1 grating to
obtain a dispersion of 1.33 Å/pixel. We set the grating for a
central wavelength of 5150 Å, which resulted in spectral coverage
from roughly 4400 Å to 5850 Å. The slit was oriented north-south
(position angle=0) and set to a width of 5.0", which resulted in
a spectral resolution of 7.9 Å. To supplement our spectra, we
obtained V-band imaging observations using the 70 cm telescope at CrAO
and the 46 cm Centurion telescope at Wise Observatory of Tel Aviv
University. The CrAO observations used the AP7p CCD, which has 512x512
pixels with a 15'x15' field of view when mounted at prime focus. The
Wise Observatory used an STL-6303E CCD with 3072x2048 pixels, with a
field of view of 75'x50' for our setup.
