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 […]

Unification models of Active Galactic Nuclei

Posted by klaurent June 10, 2026Peking

Kavli Affiliate: Claudio Ricci | Summary:This chapter presents an overview of the unification models for Active Galactic Nuclei (AGN), focusing on the physical structures, classification schemes, and evolutionary processes that characterize accreting supermassive black holes. We introduce the fundamental components of AGN, including the supermassive black hole, accretion disk, jets, outflows, broad-line and narrow-line regions, […]

Dynamic trajectory cues drive sequenced integration in approach detectors

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

Kavli Affiliate: Damon Clark | Authors: Harsh Vashistha, Natalia CB Matos, Heng Wu and Damon A Clark | Summary: Detecting approaching objects is essential for survival, and studies across animals have identified neurons and circuits selective for objects that grow in size over time, a hallmark of visual approach. However, approach as a physical process […]

Multi-timescale learning signals in Drosophila dopaminergic neurons

Posted by dbos June 10, 2026June 24, 2026UCSD / Salk

Kavli Affiliate: Dhruv Grover | Authors: Woochan Choi, Shyam Srinivasan and Dhruv Grover | Summary: Learning often requires inference over hidden task structure, including features that predict outcomes. In mammals, prediction-error signaling by midbrain dopamine neurons is considered central to learning, but how these neurons reflect the progression and stability of learning remains unclear. Using […]

Dengue virus infection in Aedes aegypti mosquito brains elicits minimal transcriptional response

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

Kavli Affiliate: Leslie B. Vosshall | Authors: Umberto Palatini, Stéphanie Dabo, Adriana Rosas-Villegas, Yael N. Tsitohay, Alexandra E. DeFoe, Nadav Shai, Louis Lambrechts and Leslie B. Vosshall | Summary: Billions of people each year are at risk from infection by dengue, Zika, yellow fever, and chikungunya viruses, which are transmitted by female Aedes aegypti mosquitoes. […]

Evidence for additional structure in the effective spin distribution hints at multiple formation pathways in GWTC-5.0

Posted by klaurent June 10, 2026MIT

Kavli Affiliate: Salvatore Vitale | Summary:The distribution of the effective inspiral spin ($χ_mathrmeff$) of the binary black holes detected by LIGO-Virgo-KAGRA can shed light on their formation pathways. We analyze the GWTC-5.0 dataset with two models-one flexible, one fully parametric-that jointly describe $χ_mathrmeff$ and primary mass. We clarify that the previously-reported skewness in the $χ_mathrmeff$ […]

From Topological Order to Mixed-State Phases: A Ground-State Probe of Fractionalized Excitations

Posted by klaurent June 10, 2026UCAS

Kavli Affiliate: Shenghan Jiang | Summary:How do we detect topological phases from a single ground state? Entanglement entropy and spectrum have long been the standard tools — but the reduced density matrix (RDM) itself contains far more information. We show that the RDM of a 2D topologically ordered system, expressed at the entanglement cut, realizes […]
