Supermassive black hole and host galaxy data and manuscript: cosmic quenching and scaling laws

Manuscript and CSV data behind the figures and tables of Xu (2025), Cosmic quenching and scaling laws for the evolution of supermassive black holes and host galaxies, MNRAS 536(4), 3554–3587, doi:10.1093/mnras/stae2766, arXiv:2501.07608. Contents: the manuscript (manuscript.pdf) and csv/ (39 CSV files: the plotted data of the figures, the table, and the result sets of the checks). Previous record of this dataset: 10.5281/zenodo.14633035. Major findings: A single parameter εb (unit m²/s³), the rate of mass and energy flow in the gas of a bulge, regulates the coevolution of supermassive black holes (SMBHs) and host galaxies; with Illustris simulations and observations it varies as εb ∝ (1+z)5/2. Host galaxies follow the mass–size relation Mb ∝ εb2/3 rb5/3 G-1, with bulge size rb ∝ (1+z)-1, the dispersion–size relation σb2 ∝ (εb rb)2/3 ∝ (1+z), and the mass–dispersion relation Mb ∝ εb-1 G-1 σb5. SMBHs pass through three phases: a rapid initial growth with LB ∝ (εb MBH)4/5 G-1/5 c, a transition with LB ∝ εb2 MBH ∝ (1+z)5, and a dormant stage with LB ∝ (εb MBH)4/3 G1/3 c-5/3. The rapid initial growth is limited by a redshift-dependent luminosity limit LX ∝ εb4/5 MBH4/5 G-1/5 c, which replaces the Eddington limit as the bound on super-Eddington growth. The analytical BH mass function, AGN mass function and quasar duty cycle predict ΦL ∝ L-1/5 at the faint end of the luminosity function, ΦAGN ∝ M-1/5 at the small-mass end of the AGN mass function, and a duty cycle U ∝ M-1/5 at high redshift.
