Machine Learning Confirms GW231123 is a “Lite” Intermediate Mass Black Hole Merger
The LIGO–Virgo–KAGRA Collaboration recently reported GW231123, a black hole merger with total mass of around 190–265 M _⊙ . This event adds to the growing evidence of “lite” intermediate mass black hole (IMBH) discoveries of postmerger black holes ≳100 M

Providing mechanically robust structural color coating technology inspired by cooperative interactions in nature. The spatial arrangement of melanin particles within the keratin matrix generates angle‐independent structural colors. Diverse functional groups in keratin and melanin contribute to interparticle and substrate adhesion, resulting in the ...

Turning Water Into a Tool: From Degradation Pathways to Functional Engineering in Halide Perovskites
Water exhibits a threshold‐dependent dual role in lead halide perovskites, acting either as a degradation trigger or as a powerful tool for defect passivation, recrystallization, and structural engineering. This review discusses how controlled water‐mediated interactions govern stability, dimensionality, and optoelectronic performance, providing ...

Probing Jet Compositions with Extreme Mass Ratio Binary Black Holes
Determining whether black hole jets are dominated by leptonic or baryonic matter remains an open question in high-energy astrophysics. We propose that extreme mass ratio binary (EMRB) black holes, where an intermediate mass secondary black hole (a ...

Little Red Dots Are Tidal Disruption Events in Runaway-collapsing Clusters
I hypothesize a physical explanation for the “little red dots” (LRDs) discovered by the James Webb Space Telescope (JWST). The first star formation in the Universe occurs in dense clusters, some of which may undergo runaway collapse and form an ...
