Local Structure and Dynamics of Three-Dimensional Covalent Organic Frameworks

Posted by klaurent Berkeley

Kavli Affiliate: Omar M. Yaghi | Summary:Resolving and controlling the local dynamical properties of covalent organic frameworks (COFs) remains a central challenge, particularly when assembled from large, flexible building units. Here, we combine synchrotron X-ray pair distribution function (PDF) analyses with machine learning-accelerated molecular dynamics (MD) simulations to resolve the local structure and dynamics of […]

VERITAS 2.3.1: Optimisation and Characterisation of the Enhanced Readout ASIC for the NewAthena Wide Field Imager

Posted by klaurent Stanford

Kavli Affiliate: Steven Allen | Summary:VERITAS 2.3.1 is the next iteration of the VErsatile Readout based on Integrated Trapezoidal Analogue Shapers (VERITAS) integrated circuit (IC) architecture for high-speed, low-noise readout of DEPleted Field Effect Transistor (DEPFET) detectors in the Wide Field Imager (WFI) on ESA’s NewAthena X-ray satellite. Building on VERITAS 2.3, which demonstrated a […]

A model for the enhanced production rate of early-type hypervelocity stars in the Galactic halo

Posted by klaurent Peking

Kavli Affiliate: Fukun Liu| Summary: About twenty late B-type hypervelocity stars (HVSs) traveling faster than the Galactic escape velocity have been discovered in the Galactic halo, many of which were ejected from the Galactic center (GC). Recently, we have advocated that these HVSs most likely formed in the nuclear star cluster (NSC) $150$–$500, rmMyr$ ago […]

The Atacama Cosmology Telescope: Passband Measurements with an Analysis of Systematic Errors

Posted by klaurent Chicago

Kavli Affiliate: Jeffrey McMahon | Summary:We present measurements of the spectral response of the four Advanced ACTPol (AdvACT) multichroic detector arrays, which observed in frequency bands centered near 30, 40, 90, 150, and 220 GHz. The passbands were measured with a Fourier transform spectrometer (FTS) combined with coupling optics that direct and match the output […]

Observation of magnetic quantum phase crossovers in a semiconductor spin ladder

Posted by klaurent Delft

Kavli Affiliate: Menno Veldhorst | Summary:Understanding collective phases of strongly correlated quantum magnets relies on theoretically tractable model systems with precise microscopic control. Antiferromagnetic spin ladders provide such a setting, hosting field-tunable gapped and gapless phases at half filling and unconventional pairing tendencies upon doping. Here, we realize a programmable Heisenberg spin ladder in a […]

The VariableTNG project: how baryonic mechanisms shape galaxy properties

Posted by klaurent Peking

Kavli Affiliate: Luis Ho | Summary:We use 50 Sobol-sampled VariableTNG simulations, varying eight subgrid parameters at fixed cosmology and initial conditions, to determine which baryonic processes regulate galaxies and black holes at $z=6$ and $z=8$. We compare the simulations with recent high-redshift measurements of the stellar mass function, star-forming main sequence, stellar and gas-phase mass-metallicity […]
