Black hole mass and variability in quasars
M. Wold, M. S. Brotherton, Z. Shang
We report on a study that finds a positive correlation between black hole mass and variability amplitude in quasars. Roughly 100 quasars at z<0.75 were selected by matching objects…
Quasar optical variability and black hole mass
M. Wold, M. S. Brotherton, Z. Shang
In order to investigate the dependence of quasar optical-UV variability on fundamental physical parameters like black hole mass, we have matched quasars from the QUEST1 variability…
The dependence of quasar variability on black hole mass
M. Wold, M. S. Brotherton, Z. Shang
In order to investigate the dependence of quasar variability on fundamental physical parameters like black hole mass, we have matched quasars from the QUEST1 Variability Survey wit…
Quasar environments at 0.5 < z < 0.8
M. Wold, M. Lacy, P. B. Lilje +1
Over the past few years, we have been collecting data with the Nordic Optical Telescope (NOT) on the galaxy environments around active galactic nuclei (AGN). Here we present some r…
