In situ coherent X-ray scattering reveals polycrystalline structure and discrete annealing events in strongly-coupled nanocrystal superlattices

Posted by dbos January 11, 2024Berkeley

Kavli Affiliate: Naomi S. Ginsberg | First 5 Authors: Matthew J. Hurley, Christian P. N. Tanner, Joshua Portner, James K. Utterback, Igor Coropceanu | Summary: Solution-phase bottom up self-assembly of nanocrystals into superstructures such as ordered superlattices is an attractive strategy to generate functional materials of increasing complexity, including very recent advances that incorporate strong […]

Nanofluidic platform for studying the first-order phase transitions in superfluid helium-3

Posted by dbos January 11, 2024Cornell

Kavli Affiliate: Jeevak M. Parpia | First 5 Authors: Petri J. Heikkinen, Nathan Eng, Lev V. Levitin, Xavier Rojas, Angadjit Singh | Summary: The symmetry-breaking first-order phase transition between superfluid phases $^3$He-A and $^3$He-B can be triggered extrinsically by ionising radiation or heterogeneous nucleation arising from the details of the sample cell construction. However, the […]

On the Performances of Estimating Stellar Atmospheric Parameters from CSST Broad-band Photometry

Posted by dbos January 11, 2024January 22, 2024Peking

Kavli Affiliate: Huawei Zhang | First 5 Authors: Ruifeng Shi, Yang Huang, Xinyi Li, Huawei Zhang, | Summary: Deriving atmospheric parameters of a large sample of stars is of vital importance to understand the formation and evolution of the Milky Way. Photometric surveys, especially those with near-ultraviolet filters, can offer accurate measurements of stellar parameters, […]

Migration and Evolution of giant ExoPlanets (MEEP) I: Nine Newly Confirmed Hot Jupiters from the TESS Mission

Posted by dbos January 11, 2024MIT

Kavli Affiliate: Avi Shporer | First 5 Authors: Jack Schulte, Joseph E. Rodriguez, Allyson Bieryla, Samuel N. Quinn, Karen A. Collins | Summary: Hot Jupiters were many of the first exoplanets discovered in the 1990s, but in the decades since their discovery, the mysteries surrounding their origins remain. Here, we present nine new hot Jupiters […]

Constraining the clustering and 21-cm signature of radio galaxies at cosmic dawn

Posted by dbos January 11, 2024Cambridge

Kavli Affiliate: George Efstathiou | First 5 Authors: Sudipta Sikder, Rennan Barkana, Anastasia Fialkov, , | Summary: The efficiency of radio emission is an important unknown parameter of early galaxies at cosmic dawn, as models with high efficiency have been shown to modify the cosmological 21-cm signal substantially, deepening the absorption trough and boosting the […]
