Achieving Large and Anisotropic Spin‐Mediated Thermal Transport in Textured Quantum Magnets
Advanced Functional Materials, Volume 35, Issue 12, March 18, 2025.An advanced solvent‐cast cold pressing method is developed to synthesize highly textured quantum magnets. By aligning spin chains in Ca2CuO3 perpendicular to the pressing direction, a spin‐mediated thermal conductivity of 10 ± 1 W m⁻¹ K⁻¹ is achieved, the highest reported for polycrystalline quantum materials.

Counting the Unseen. II. Tidal Disruption Event Rates in Nearby Galaxies with REPTiDE
The Astrophysical JournalTidal disruption events (TDEs) are a class of transients that occur when a star is destroyed by the tides of a massive black hole (MBH). Their rates encode valuable MBH demographic information, but this can only be extracted if accurate TDE rate ...

Constraints on the Growth and Spin of the Supermassive Black Hole in M32 From High Cadence Visible Light Observations [PDF]
, 2017 We present 1-second cadence observations of M32 (NGC221) with the CHIMERA instrument at the Hale 200-inch telescope of the Palomar Observatory. Using field stars as a baseline for relative photometry, we are able to construct a light curve of the nucleus

MOCCA Survey Database I: Dissolution of tidally filling star clusters harbouring BH subsystems
, 2019 We investigate the dissolution process for dynamically evolving star clusters embedded in an external tidal field by exploring the MOCCA Survey Database I, with focus on the presence and evolution of a stellar-mass black hole subsystem. We argue that the

The Angular Momenta of Neutron Stars and Black Holes as a Window on Supernovae [PDF]
, 2011 It is now clear that a subset of supernovae display evidence for jets and are observed as gamma-ray bursts. The angular momentum distribution of massive stellar endpoints provides a rare means of constraining the nature of the central engine in core ...

mocca code for star cluster simulations – III. Stellar-mass black holes in the globular cluster M22 [PDF]
, 2014 Using a Monte Carlo code, we construct a dynamic evolutionary model of the Galactic globular cluster M22 (NGC6656). The initial conditions are chosen so that, after about 12Gyr of stellar and dynamical evolution, the model is an approximate fit to the ...

Thermally Induced Gelling Systems Based on Patchy Polymeric Micelles
Advanced Functional Materials, Volume 35, Issue 12, March 18, 2025.A novel strategy to design thermally induced gelling systems with tunable material properties is reported. Polymeric mixed‐shell micelles displaying multiple thermosensitive patchy domains formed hydrogels by assembling into well‐entangled worm‐like network structures upon heating to body temperature. The patchy micelle design significantly affects the

On the coexistence of stellar-mass and intermediate-mass black holes in globular clusters [PDF]
, 2014 In this paper, we address the question: What is the probability of stellar-mass black hole (BH) binaries co-existing in a globular cluster with an intermediate-mass black hole (IMBH)?

Advanced Functional Materials, EarlyView.A lack of standard approaches for testing and reporting the performance of metal halide perovskites and organic semiconductor radiation detectors has resulted in inconsistent interpretation of performance parameters, impeding progress in the field. This Perspective recommends key metrics and experimental details, which are suggested for reporting in ...

Dynamics Around Supermassive Black Holes: Extreme-mass-ratio Inspirals as Gravitational-wave Sources
The Astrophysical JournalSupermassive black holes and their surrounding dense stellar environments nourish a variety of astrophysical phenomena. We focus on the distribution of stellar-mass black holes around the supermassive black hole and the consequent formation of extreme ...
