Localizing Dynamically Formed Black Hole Binaries in Milky Way Globular Clusters with LISA
The Astrophysical Journal LettersThe dynamical formation of binary black holes (BBHs) in globular clusters (GCs) may contribute significantly to the observed gravitational-wave (GW) merger rate.

Multi‐Soliton Microcombs Enable Ultrafast Nanometric‐Precision Ranging and Photon‐Level Detection
Advanced Science, EarlyView.Our work first demonstrates dual‐multi‐soliton ranging and confirms its multifunctional capability. The method achieves ultrafast and nanometric‐precision measurement. For practical applications, we further extend the multi‐soliton states to photon‐level ranging.

Machine Learning Confirms GW231123 is a “Lite” Intermediate Mass Black Hole Merger
The Astrophysical Journal LettersThe 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

Experimental Joint Estimation of Phase and Phase Diffusion Via Deterministic Bell Measurements
Advanced Science, EarlyView.This work employs Bell measurement, a form of entangling measurement, to estimate both the phase and its fluctuations in an optical interferometer. By incorporating a novel quantum effect at the measurement stage, the proposed method achieves the ultimate precision limit and demonstrates the significant potential of entangling measurements in multi ...

Advanced Science, EarlyView.Inspired by nature's competitive maneuvers, this study introduces a combustion‐driven soft actuator that powers a multi‐modal “Jump‐and‐Fly Catbot” (JFC). With millisecond response, high‐force output (over 70 times its weight) and precise control (error within 5%), the robot can jump, fly, hover, and escape from challenging environments, achieving ...

Robust Smart Superhydrophobic Cilia
Advanced Science, EarlyView.To date, ciliated surfaces cannot withstand mechanical damage because cilia/wires are inherently fragile. By aligning magneto‐responsive, flexible, superhydrophobic microwires on the sidewall of vertical frames, the frames act as armors to protect microwires from mechanical damage; when needed, the microwires re‐align uprightly under a magnet field to ...

Gravitational Waves from Gravitational Collapse
Living Reviews in Relativity, 2011 Gravitational-wave emission from stellar collapse has been studied for nearly four decades. Current state-of-the-art numerical investigations of collapse include those that use progenitors with more realistic angular momentum profiles, properly treat ...

Structure and Skewness of the Effective Inspiral Spin Distribution of Binary Black Hole Mergers
The Astrophysical JournalThe detection of gravitational waves has brought to light a population of binary black holes that merge within a Hubble time. Multiple formation channels can contribute to this population, making it difficult to definitively associate particular ...
