Reversible Electron-Beam Patterning of Colloidal Nanoparticles at Fluid Interfaces

Posted by dbos Berkeley

Kavli Affiliate: Naomi S. Ginsberg | First 5 Authors: Jonathan G. Raybin, Ethan J. Dunsworth, Veronica Guo, Naomi S. Ginsberg, | Summary: The directed self-assembly of colloidal nanoparticles (NPs) using external fields guides the formation of sophisticated hierarchical materials but becomes less effective with decreasing particle size. As an alternative, electron-beam-driven assembly offers a potential […]

Inter-Layer Correlation of Loop Current Charge Density Wave on the Bilayer Kagomé Lattice

Posted by dbos UCAS

Kavli Affiliate: Gang Su | First 5 Authors: Jin-Wei Dong, Yu-Han Lin, Ruiqing Fu, Gang Su, Ziqiang Wang | Summary: Loop current order has been suggested as a promising candidate for the spontaneous time-reversal symmetry breaking $2a_0 times 2a_0$ charge density wave (CDW) revealed in vanadium-based kagom’e metals avs ($A$ = K, Rb, Cs) near […]

HD 222237 b: a long period super-Jupiter around a nearby star revealed by radial-velocity and Hipparcos-Gaia astrometry

Posted by dbos MIT

Kavli Affiliate: Avi Shporer | First 5 Authors: Guang-Yao Xiao, Fabo Feng, Stephen A. Shectman, C. G. Tinney, Johanna K. Teske | Summary: Giant planets on long period orbits around the nearest stars are among the easiest to directly image. Unfortunately these planets are difficult to fully constrain by indirect methods, e.g., transit and radial […]

Massive Star Formation Starts in Sub-virial Dense Clumps Unless Resisted by Strong Magnetic Fields

Posted by dbos Peking

Kavli Affiliate: Ke Wang | First 5 Authors: Ke Wang, Yueluo Wang, Fengwei Xu, , | Summary: The initial conditions are critical for understanding high-mass star formation, but are not well observed. Built on our previous characterization of a Galaxy-wide sample of 463 candidate high-mass starless clumps (HMSCs), here we investigate the dynamical state of […]

Parameter constraints for accreting millisecond pulsars with synthetic NICER data

Posted by dbos MIT

Kavli Affiliate: Deepto Chakrabarty | First 5 Authors: Bas Dorsman, Tuomo Salmi, Anna L. Watts, Mason Ng, Satish Kamath | Summary: Pulse profile modelling (PPM) is a technique for inferring mass, radius and hotspot properties of millisecond pulsars. PPM is now regularly used for analysis of rotation-powered millisecond pulsars (RMPs) with data from the Neutron […]

Extremely Dense Gas around Little Red Dots and High-redshift AGNs: A Non-stellar Origin of the Balmer Break and Absorption Features

Posted by dbos Peking

Kavli Affiliate: Kohei Inayoshi | First 5 Authors: Kohei Inayoshi, Roberto Maiolino, , , | Summary: The James Webb Space Telescope (JWST) has uncovered low-luminosity active galactic nuclei (AGNs) at high redshifts of $zgtrsim 4-7$, powered by accreting black holes (BHs) with masses of $sim 10^{6-8}~M_odot$. These AGN populations are considered crucial for understanding early […]

Enhancing Direct Detection of Higgsino Dark Matter

Posted by dbos Stanford

Kavli Affiliate: Peter W. Graham | First 5 Authors: Peter W. Graham, Harikrishnan Ramani, Samuel S. Y. Wong, , | Summary: While much supersymmetric WIMP parameter space has been ruled out, one remaining important candidate is Higgsino dark matter. The Higgsino can naturally realize the “inelastic dark matter" scenario, where the scattering off a nucleus […]

A STING-CASM-GABARAP Pathway Activates LRRK2 at Lysosomes

Posted by dbos Yale

Kavli Affiliate: Shawn Ferguson | Authors: Amanda Bentley-DeSousa and Shawn Ferguson | Summary: Mutations that increase LRRK2 kinase activity have been linked to Parkinson’s disease and Crohn’s disease. LRRK2 is also activated by lysosome damage evoked by chemical and pathogenic stimuli. However, the endogenous cellular mechanisms that control LRRK2 kinase activity are not well understood. […]

Confirming the Tidal Tails of the Young Open Cluster Blanco 1 with TESS Rotation Periods

Posted by dbos MIT

Kavli Affiliate: Andrew M. Vanderburg | First 5 Authors: Lizhou Sha, Andrew M. Vanderburg, Luke G. Bouma, Chelsea X. Huang, | Summary: Blanco 1 is an $approx 130,mathrm{Myr}$ open cluster located 240 pc from the Sun below the Galactic plane. Recent studies have reported the existence of diffuse tidal tails extending 50-60 pc from the […]
