ZLK oscillations in Sgr A* triples enhance dual-line GW source formation rates by a factor of 5-10.
An improved distribution-function modeling technique applied to thousands of stars yields a 4 million solar-mass central black hole and a total mass of 2.0-2.3 x 10^7 solar masses within 10 pc of the Milky Way nucleus.
DAMPE independently detects the Fermi bubbles at 26 sigma and the Galactic center GeV excess at 7 sigma, with the excess spectrum and morphology matching Fermi-LAT and fitting a 50 GeV dark matter particle annihilating to b quarks.
MOG produces distinct orbital precession and sky-projected deviations for S-stars that grow with the parameter α and can resemble dark matter effects while remaining testable against GR.
Bounded polymerization in asymmetric LQG-inspired bounce models makes shell-crossing singularities unavoidable for inhomogeneous dust collapse, whereas unbounded polymerization in non-bouncing models permits avoidance for suitable decreasing initial profiles.
Larger supermassive black holes drive greater atmospheric heating, mass loss, and near-total ozone depletion on exoplanets, with effects strongest in energy-driven winds and closer to the galactic center.
Parameter scans of a hand-set effective model show that adding dark matter around a rotating black hole slows the intermediate-axis flip frequency of a coherent triaxial structure relative to Kerr.
N-body simulations show that mutual interactions between Terzan 2, 4, and 5 raise mass-loss rates for the smaller clusters and drive prolate deformations absent in isolated runs.
A review summarizing detection methods, population statistics, and coevolution of supermassive black holes with host galaxies from early universe observations and simulations.

Formation of shell-crossing singularities in effective gravitational collapse models with bounded and unbounded polymerizations
Bounded polymerization in asymmetric LQG-inspired bounce models makes shell-crossing singularities unavoidable for inhomogeneous dust collapse, whereas unbounded polymerization in non-bouncing models permits avoidance for suitable decreasing initial profiles.
