From Nuclear Star Clusters to Little Red Dots: Black Hole Growth, Mergers, and Tidal Disruptions
The Astrophysical JournalLittle Red Dots, discovered by the James Webb Space Telescope, are hypothesized to be active galactic nuclei containing a supermassive black hole, possibly surrounded by a dense stellar cluster, large amounts of gas, and likely by a population of stellar-

Axion Black Hole Solution in Non‐Metricity Gravity
Fortschritte der Physik, Volume 74, Issue 2, February 2026.Abstract A static, spherically symmetric black hole solution in symmetric teleparallel (non‐metricity) gravity sourced by an axion field is constructed. Starting from the modified field equations, exact configurations are obtained characterized by the mass M$M$ and an axion–geometry coupling β$\beta$, with temporal metric function A(r)=1−2Mr+βr$A(r)=1-\

The GLEAMing of the first supermassive black holes
Publications of the Astronomical Society of Australia, 2020 AbstractWe present the results of a new selection technique to identify powerful ($L_{\rm 500\,MHz} \gt 10^{27}\,\text{WHz}^{-1}$) radio galaxies towards the end of the Epoch of Reionisation. Our method is based on the selection of bright radio sources showing radio spectral curvature at the lowest frequency (${\sim}100\,\text{MHz}$) combined with the ...

Gravitational Time Potential Energy
Advances in Astronomy, Volume 2026, Issue 1, 2026.We extend the Einstein equivalence principle via a supplementary local energy equivalence postulate and propose the gravitational time potential energy (GTP) framework: a time‐dimensional scalar potential accumulating continuously with the proper duration of gravitational action. This framework may provide a potential classical interpretation for alpha

Formation of Supermassive Black Hole
, 2023 The Star formation model is used in this study to examine the formation of quasars and Supermassive Black Holes (SMBH).The difference in SMBH formation is that materials that fall into the disk surrounding black holes do not contribute to their final ...

Advances in Astronomy, Volume 2026, Issue 1, 2026.We examine the weak cosmic censorship conjecture (WCCC) violation by throwing a charged and rotating test particle into a Kerr–Newman–modified gravity black hole (KN–MOG BH). The result depends on several factors, such as the relative sign of the particle’s charge and its direction of rotation with respect to black hole (BH).

Stellar capture by a supermassive black hole
, 2013 Dense, million-strong clusters of stars are often found at the centers of galaxies. This video shows the fate of some of these stars, and an ill-fated planet, that venture too close to the cluster's central supermassive black hole.
