Winds Versus Jets in Active Galactic Nuclei

David Garofalo, Chandra B. Singh, Atticus Magerko +3

The well-established anti-correlation between disk winds and relativistic jets in X-ray binaries is often interpreted in a scale-invariant black hole accretion context. If so, acti…

A GRMHD-Calibrated Semi-Analytical Model for Hot Sub-Keplerian Accretion Flows in Kerr Spacetime

Nabin Bhushal, Manil Khatiwada, Yogesh Maharjan +2

We develop a simple, semi-analytical, kinematic model for hot, thick accretion flows, constructed by interpolating between Keplerian and free-fall geodesic solutions in the Kerr me…

How a Klein-Nishina Modified Eddington limited accretion explains rapid black hole growth in the early universe

Jackson Frangos, Erick Rosen, Michael Williams +2

The discovery of quasars and their supermassive black holes (SMBHs) over merely hundreds of millions of years after the Big Bang generates tension with the idea…

Characteristics of Powerful Radio Galaxies

Chandra B. Singh, Michael Williams, David Garofalo +3

Mature radio galaxies such as M87 belong to a specific subclass of active galaxies (AGN) whose evolution in time endows them with five distinguishing characteristics, including (1)…

The properties of FR0 radio galaxies as intermediate objects in the evolution of radio galaxies

David Garofalo, Chandra B. Singh, Eddie Harmon +2

The counter-rotation between black holes and accretion disk configuration was introduced over a decade ago to elucidate the nature of the radio loud/radio-quiet dichotomy and the j…

The massive black holes, high accretion rates, and non-tilted jet feedback, of jetted AGN triggered by secular processes

Chandra B. Singh, David Garofalo

That jetted active galactic nuclei (AGN) are also hosted in spiral galaxies is now well established. Our understanding of how such objects might fit in the radio loud AGN subclass…
