Abstract:
We report first-time reverberation-mapping results for 14 active
galactic nuclei (AGNs) from the ongoing Monitoring AGNs with Hβ
Asymmetry campaign (MAHA). These results utilize optical spectra
obtained with the Long Slit Spectrograph on the Wyoming Infrared 2.3m
Telescope between 2017 November and 2023 May. MAHA combines
long-duration monitoring with high cadence. We report results from
multiple observing seasons for nine of the 14 objects. These results
include Hβ time lags, supermassive black hole masses, and
velocity-resolved time lags. The velocity-resolved lags allow us to
investigate the kinematics of the broad-line region.
Description:
In this paper, we present results from reverberation-mapping (RM) of
14 Monitoring AGNs with Hβ Asymmetry (MAHA) that have not
previously had successful time lags published. We conducted our
observations using the Wyoming Infrared Observatory's (WIRO) 2.3m
telescope with the Long Slit Spectrograph (4000-7000Å).
We measured the 5100Å continuum flux densities from our calibrated
spectra by averaging the flux density spanning the wavelength range of
5075-5125Å in the rest frame. See Section 2.2.
We followed MAHA I (Du+ 2018, J/ApJ/869/142) in supplementing our
continuum light curves with survey photometry when available and of
sufficiently small uncertainties; see Section 2.3.
