GRRMHD simulations of TDE debris disks reveal thermal instability and collapse within weeks, producing soft X-ray excess followed by a sharp luminosity drop that resembles AT2021ehb observations.
Direct collapse black holes born at z=25.7 grow at half-Eddington rate to produce overmassive black hole galaxies at z~10 with M_BH/M_* ~0.01, matching JWST observations of GN-z11, UHZ1, and GHZ9 through initial star-formation suppression and later Pop III supernova metal blowout.
A simulation study finds that a hot gas halo at galaxy total mass ~10^12.5 solar masses suppresses cool gas accretion, driving a redshift-independent turnover in the stellar-to-total mass ratio via reduced in-situ star formation efficiency.
Halo-driven transient rapid growth followed by thermodynamic suppression explains over-massive black holes and Little Red Dots as precursors to standard SMBH-galaxy coevolution.
Lumina runs a 500 cMpc radiation-hydrodynamic simulation combining IllustrisTNG galaxy formation with six-bin M1 radiation transport to predict late stellar-driven HI reionization ending around z=4.75 and AGN-driven HeII reionization nearly complete by z=3.
The paper identifies underproduction of oxygen in low-mass simulated dwarf galaxies as the likely cause of missing OVI in the CGM, based on comparisons across two simulation suites.
LRDs require Compton-thick gas at moderate metallicity plus high accretion rates producing weak X-rays to explain their non-detection, implying they are not chemically pristine.
Horizon-AGN shows galaxy and black hole merger rates both rise with stellar mass and fall with redshift, peaking near z=2-3, establishing a direct evolutionary link from galaxy interactions to black hole coalescences.
Spectra of the western eROSITA bubbles reveal two uniform components at 0.60 keV and 0.21 keV with sub-solar abundances, plus a geometrical model constraining horizontal size to ~6 kpc but leaving vertical extent uncertain.
UV background suppresses NEI in galaxy haloes, restoring equilibrium shock thresholds and producing extended absorption columns for OVI, CIV, and HI beyond the virial radius.
A large collaboration compiles and compares merger rate predictions for massive black holes across multiple galaxy formation models to forecast LISA detections and quantify uncertainties.
XRISM data show a ~2 keV cooler gas phase with 300-400 km/s dispersion and bulk motion in the central Perseus cluster, distinct from the single-temperature gas beyond 60 kpc.
COLIBRE calibrates supernova and AGN feedback parameters in multi-phase ISM cosmological simulations using emulator-based fitting to reproduce the z=0 galaxy stellar mass function and size-stellar mass relation at three resolutions.
Simulations show that bursty supernova feedback produces fewer bright [OIII] emitters by z=5 than smooth feedback due to less effective metal enrichment, while [OIII] traces shock-heated and radiatively ionized gas.

How Overmassive Black Holes Formed at Cosmic Dawn
