The Hard-to-soft Transition of GX 339–4 as Seen by Insight–HXMT
The Astrophysical Journal, 2023 We present an analysis of the relativistic reflection spectra of GX 339–4 during the hard-to-soft transition of its 2021 outburst observed by Insight–HXMT.

Tidal Disruption of a Main-sequence Star by an Intermediate-mass Black Hole: A Bright Decade [PDF]
Astrophysical Journal, 2018 There has been suggestive evidence of intermediate-mass black holes (IMBHs; 103−5 M⊙) existing in some globular clusters (GCs) and dwarf galaxies, but IMBHs as a population remain elusive.

Advanced Functional Materials, EarlyView.Ozone‐based gas‐phase metal‐assisted chemical etching enables unprecedented room‐temperature fabrication of high‐quality silicon nanowires. The superior oxidation potential of O3 drives rapid vertical etching (1 µm min−1) while maintaining exceptional structural integrity. The pristine nanowire surfaces enable high‐performance core‐shell photodetectors

Sowing the seeds of massive black holes in small galaxies: Young clusters as the building blocks of Ultra-Compact-Dwarf Galaxies [PDF]
, 2014 Interacting galaxies often have complexes of hundreds of young stellar clusters of individual masses $\sim 10^{4-6}~M_\odot$ in regions that are a few hundred parsecs across.

Radial anisotropy in ω Cen limiting the room for an intermediate-mass black hole [PDF]
, 2017 Finding an intermediate-mass black hole (IMBH) in a globular cluster (or proving its absence) would provide valuable insights into our understanding of galaxy formation and evolution.

Intermediate Mass Black Holes in Star Clusters [PDF]
Progress of Theoretical Physics Supplement, 2004 We have performed N-body simulations of the formation of intermediate mass black holes in young star clusters and the subsequent dynamical evolution of star clusters containing massive black holes. Our simulations show that runaway merging of massive main-sequence stars can produce an intermediate mass black hole in the M82 cluster MGG-11 if the ...

Fast Neutron Detector Based on Hybrid 2D Perovskite Thin Films
Advanced Functional Materials, EarlyView.This work presents the direct detection of fast neutrons using flexible hybrid 2D perovskite (PEA2PbBr4) thin‐film detectors. Thanks to their high low‐Z elements content and good charge transport, these materials enable efficient neutron detection. The thin film configuration allowed the operation at low voltage, and offer scalability, flexibility, and

Journal of High Energy Physics, 2023 The Maxwell invariant plays a fundamental role in the mathematical description of electromagnetic fields in charged spacetimes. In particular, it has recently been proved that spatially regular scalar fields which are non-minimally coupled to the Maxwell

Intermediate-mass black hole growth and feedback in dwarf galaxies at high redshifts [PDF]
Monthly notices of the Royal Astronomical Society, 2018 Intermediate-mass black holes (IMBHs; masses between $100\rm{\, and \,}10^{6} \, \mathrm{M}_{\odot }$) historically comprise of an elusive population compared to stellar-mass and supermassive black holes (BHs).
