Tidal stripping of stars near supermassive black holes
Published 2012-12-01“…In a binary system composed of a supermassive black hole and a star orbiting the hole in an equatorial, circular orbit, the stellar orbit will shrink due to the action of gravitational radiation, until the star fills its Roche lobe outside the Innermost Stable Circular Orbit (ISCO) of the hole or plunges into the hole. …”

Evolution of Supermassive Black Hole Feedback in Galaxy Clusters
Published 2024“…Only in galaxy clusters, where the CGM gets hot enough to glow in X-rays, can the entire baryon cycle be observed– from the rapid cooling of the intracluster medium (ICM) that contributes to the CGM and level of star formation in the central galaxy, to the eventual feeding and triggering of feedback from the largest supermassive black holes (SMBHs) residing in them. This cooling and subsequent feedback from these active galactic nuclei (AGN) is the primary driver of the baryon cycle and evolution of the largest, brightest cluster galaxies (BCGs), quenching their expected levels of cooling and star formation by up to two orders of magnitude. …”

Cosmological growth and feedback from supermassive black holes
Published 2013“…We develop a simple evolutionary scenario for the growth of supermassive black holes (BHs), assuming growth due to accretion only, to learn about the evolution of the BH mass function from $z=3$ to 0 and from it calculate the energy budgets of different modes of feedback. …”
