Cosmic quenching and scaling laws for the evolution of supermassive black holes and host galaxies
Zhijie Jay Xu
Observations suggest an SMBH-host coevolution. We consider the mass and energy flow in a bulge suffused by gases of varying temperatures. By assuming the rate of energy flow indepe…

Dark matter halo mass functions and density profiles from mass and energy cascade
Zhijie, Xu
Without relying on a spherical or ellipsoidal collapse model, we analytically derive the halo mass function and cuspy halo density (inner slope of -4/3) based on the mass and energ…

Cold freeze out of superheavy dark matter and Hubble tension
Zhijie, Xu
We propose a unified dark matter framework, the "X miracle", in which dark matter consists of superheavy, nonthermal X particles whose relic abundance is set by annihilation or dec…
