Black hole masses, accretion rates and hot- and cold-mode accretion in radio galaxies at z ∼ 1

Black hole masses, accretion rates and hot- and cold-mode accretion in radio galaxies at z ∼ 1

Understanding the evolution of accretion activity is fundamental to our understanding of how galaxies form and evolve over the history of the Universe. We analyse a complete sample of 27 radio galaxies which includes both high-excitation galaxies (HEGs) and low-excitation galaxies (LEGs), spanning a...

Zusammenfassung:Understanding the evolution of accretion activity is fundamental to our understanding of how galaxies form and evolve over the history of the Universe. We analyse a complete sample of 27 radio galaxies which includes both high-excitation galaxies (HEGs) and low-excitation galaxies (LEGs), spanning a mnrasrow redshift range of 0.9
