The emergence of the X-ray luminosity/cluster richness relation for radio galaxies
David Garofalo, Chandra B. Singh
The idea that mergers are more likely in dense groups or clusters coupled with the assumption that such events lead to cold gas flows onto black holes, suggests a direct relationsh…
Evidence for radio loud to radio quiet evolution from red and blue quasars
David Garofalo, Katie Bishop
Recent work on red and blue quasi-stellar objects (QSOs) has identified peculiar number distributions as a function of radio loudness that we explore and attempt to explain from th…
Spin of the M87 black hole
David Garofalo
Spin measurement of the 6.5 billion solar mass black hole in M87 from the Event Horizon Telescope image is the latest in a series that span a wide range in values, but that tend to…
Why radio quiet quasars are preferred over radio loud quasars regardless of environment and redshift
David Garofalo, Max North, Leanne Belga +1
Evidence has accumulated suggesting the clustering of radio loud quasars is greater than for radio quiet quasars. We interpret these results in a context in which the fraction of r…
