Discovery of 35 high-redshift dwarf galaxies with radio AGN showing jet powers of 10^42-10^44 erg/s and efficiencies >=10% in over half the sample.
Lenient heavy-seed models in BRAHMA simulations produce black hole merger rates above 100 per year and near-unity occupation fractions down to low-mass galaxies, while strict models yield only about 1 merger per year and occupation fractions below 10 percent for galaxies under 10^8 solar masses.
Super-Eddington accretion boosts predicted LISA detections of high-redshift black hole binaries to ~64 per year while dropping ET detections to ~4 per year, compared to ~32 and ~64 under Eddington-limited growth.
N-body simulations demonstrate that the inspiral of globular clusters in UGC 7346 results in the formation of a nuclear star cluster with mass (4.1-4.5)×10^5 solar masses within 1.5 Gyr.
Simulations combining MICADO imaging and HARMONI kinematics show that variations in nuclear star cluster inner surface-brightness slope affect IMBH mass estimates derived via Jeans Anisotropic Modeling.
A review summarizing detection methods, population statistics, and coevolution of supermassive black holes with host galaxies from early universe observations and simulations.

Supermassive Black Hole Assembly from Heavy Seeds with Dynamical Friction in the BRAHMA Simulations: Implications for JWST, LISA, and the Local Universe
Lenient heavy-seed models in BRAHMA simulations produce black hole merger rates above 100 per year and near-unity occupation fractions down to low-mass galaxies, while strict models yield only about 1 merger per year and occupation fractions below 10 percent for galaxies under 10^8 solar masses.
