Towards imaging Earth’s large-scale structures by directional geoneutrino detection with Ocean Bottom Detector

Posted by klaurent June 11, 2026June 24, 2026Tokyo

Kavli Affiliate: Kunio Inoue | Summary:Geoneutrinos, electron antineutrinos produced by radioactive decays of heat-producing elements (HPEs) within the Earth, provide unique insights into Earth’s interior and heat budget since their first detection in 2005 by KamLAND. Conventional geoneutrino detectors currently provide integrated global information and lack the capability to spatially resolve structures deep within the […]

Ultraviolet Imaging of SR 12 c with HST/WFC3: Accretion and Variability of a Giant Planet at the End Stages of Growth

Posted by klaurent June 11, 2026June 24, 2026Peking

Kavli Affiliate: Gregory Herczeg | Summary:Many details of the gas accretion phase during giant planet formation remain untested. We present new 0.2$unicodex2013$0.7 $μ$m UV-through-red optical imaging of the young, wide-orbit planetary-mass companion SR 12 c from the Wide Field Camera 3 (WFC3) instrument on board the Hubble Space Telescope. SR 12 c exhibits strong accretion-related […]

Supermassive Black Hole Assembly from Heavy Seeds with Dynamical Friction in the BRAHMA Simulations: Implications for JWST, LISA, and the Local Universe

Posted by klaurent June 11, 2026June 24, 2026MIT

Kavli Affiliate: Mark Vogelsberger | Summary:The JWST discoveries of supermassive black holes (BHs) at $z gtrsim 5$ may provide key insights into their seeding origins. Using new $[18-72~rm Mpc]^3$ BRAHMA cosmological simulations, we investigate how variations in heavy-seed prescriptions, coupled with a subgrid dynamical friction model, shape BH populations at $z sim 5$ and $z […]

Striatal ensembles specify and control granular forelimb actions

Posted by dbos June 10, 2026June 24, 2026Columbia

Kavli Affiliate: Rui Costa and Darcy Peterka | Authors: Ines Rodrigues-Vaz, Vivek R. Athalye, Darcy S. Peterka and Rui M. Costa | Summary: The striatum is classically thought to modulate action vigor and reinforcement, but whether it specifies and controls ongoing actions at a fine scale remains unclear. Here, we test whether striatal activity can […]

A Neuronal Gene Expression Program Underlying Sustained Network Activity

Posted by dbos June 10, 2026June 24, 2026UCSF

Kavli Affiliate: Yuh Nung Jan | Authors: J. Wren Kim, Rebecca Eliscu, Adeline JH Yong, Sua Lee, Yuh Nung Jan, Taeyoung Hwang, Liana F Lareau and Nicholas T Ingolia | Summary: Neurons function within interconnected networks and must continuously adjust their firing properties to maintain stable network activity. Although these adjustments require long-lasting molecular changes, […]

A non-canonical pallidothalamic pathway for motor control

Posted by dbos June 10, 2026June 24, 2026UCSF

Kavli Affiliate: Jeanne Paz | Authors: Isaac Y.M. Chang and Jeanne T. Paz | Summary: Coordinated movement relies on interactions between the basal ganglia and the thalamus, yet the circuits linking these structures are not fully understood. Here, we dissect a non-canonical basal ganglia output pathway, from the external globus pallidus (GPe) to the nucleus […]

Carbon Abundances in Metal-Poor Stars Reveal Distinct Galaxy and Star Formation Pathways in the Early Universe

Posted by klaurent June 10, 2026June 24, 2026MIT

Kavli Affiliate: Anna Frebel | Summary:Carbon-enhanced metal-poor (CEMP; with $rm[Fe/H] le -2.0$ and $rm[C/Fe] ge 0.7$) stars preserve information about early chemical enrichment, low-mass star formation, and the hierarchical assembly of galaxies. In this study, we have compiled an extensive literature sample of 1032 stellar carbon abundances spanning the metal-poor Milky Way halo (437 stars), […]

Dynamical Control of Superconductivity in Superconductor-Ferromagnet Bilayers

Posted by klaurent June 10, 2026June 24, 2026Cornell

Kavli Affiliate: Debanjan Chowdhury | Summary:We study a simplified model of a ferromagnetic metal proximitized by a fully-gapped $s-$wave superconductor and integrated with a microwave resonator. The low-energy excitations in the combined system consist of ferromagnetic magnons, Bogoliubov excitations of the superconductor, and cavity photons. We show here that when the magnons and photons have […]

DESI as sparse Integral Field Spectrograph I: Spatially resolved chemical enrichment in star-forming galaxies at $zleq0.1$

Posted by klaurent June 10, 2026June 24, 2026Peking

Kavli Affiliate: Luis Ho | Summary:We present a spatially resolved chemical abundance analysis of 2291 star-forming galaxies at $z leq 0.1$, spanning nearly four orders of magnitude in stellar mass ($8 le rm log (M_star/M_odot) le 11.5$), by exploiting the multi-fibre spectra from the Dark Energy Spectroscopic Instrument (DESI) as a sparse integral field spectrograph.

Charting the emergent low-dimensional manifold of quantum materials

Posted by klaurent June 10, 2026June 24, 2026Cornell

Kavli Affiliate: Debanjan Chowdhury | Summary:The periodic table of elements transformed chemistry by revealing simple organizing principles underlying atomic behavior. Despite decades of effort, no analogous framework has emerged for crystalline materials — their microscopic complexity and vast configurational space have defied reduction to fundamental organizing principles. Current databases catalog thousands of synthesized materials, but […]
