Black Holes in the Shadow: The Missing High-Ionization Lines in the Earliest JWST AGNs

Kavli Affiliate: Roberto Maiolino | First 5 Authors: Greta Zucchi, Greta Zucchi, , , | Summary: Observations with the James Webb Space Telescope (JWST) have uncovered a substantial population of high-redshift, broad-line active galactic nuclei (AGNs), whose properties challenge standard models of black hole growth and AGN emission. We analyze a spectroscopic sample of 34 […]

Rearing condition affects behavioral response to cross-modal expectancy violation paradigm in zebra finche

Kavli Affiliate: Sarah Woolley | Authors: Isabella Catalano and Sarah Cushing Woolley | Summary: Interacting in a multimodal world, including recognizing other individuals across multiple sensory modalities, is important for animals who rely on social relationships for survival. Social and sensory experiences shape how multisensory information is processed and integrated; however, we have less understanding […]

Astrocyte SEMA3C reduction improves Rett Syndrome phenotypes

Kavli Affiliate: Nicola Allen | Authors: Krissy A Lyon, Adrien Paumier, Ananya Kandikonda, Andrea Melendez and Nicola J Allen | Summary: During typical neurodevelopment, astrocytes secrete proteins that support neuronal connectivity. This process is disrupted in Rett Syndrome (RTT), a regressive neurodevelopmental disorder characterized by motor, sensory, and cognitive impairments. While astrocytes typically promote neuron […]

JWST Catches a Strongly Gravitationally Lensed AGN In Transition from Type II to Type I

Kavli Affiliate: Michael D. Gladders | First 5 Authors: Michael K Florian, Michael K Florian, , , | Summary: JWST has enabled the discovery of a statistical sample of obscured (type II) active galactic nuclei (AGN) at cosmic noon. Studies comparing those type II AGN with type I AGN at that epoch have reinforced the […]

Chandra/HETG and NuSTAR Observations of V750 Ara, a $γ,$Cas-type Star

Kavli Affiliate: David P. Huenemoerder | First 5 Authors: David P. Huenemoerder, David P. Huenemoerder, , , | Summary: We present 197 ks HETG and 95 ks NuSTAR spectra of the $gamma,$Cas-type object V750 Ara. The high-resolution X-ray spectra show that the target is similar to other objects of this class. Data are interpreted under […]

Unifying Tree Search Algorithm and Reward Design for LLM Reasoning: A Survey

Kavli Affiliate: Xiang Zhang | First 5 Authors: Jiaqi Wei, Jiaqi Wei, , , | Summary: Deliberative tree search is a cornerstone of modern Large Language Model (LLM) research, driving the pivot from brute-force scaling toward algorithmic efficiency. This single paradigm unifies two critical frontiers: textbfTest-Time Scaling (TTS), which deploys on-demand computation to solve hard […]

Synchronized path-integration recalibration but distinct landmark-control dynamics in head direction and CA1 place cells

Kavli Affiliate: James Knierim | Authors: Ravikrishnan P Jayakumar, Yotaro Sueoka, Marissa K Ferreyros, Brian Y Li, Manu S Madhav, Xingyu Chen, James J Knierim and Noah J Cowan | Summary: Accurate spatial navigation relies on path integration, a process of tracking one’s location by integrating self-motion cues. Path integration uses a gain factor relating […]

Stochastic numerical head phantoms to enable virtual imaging studies of transcranial photoacoustic computed tomography

Kavli Affiliate: Lihong V. Wang | First 5 Authors: Hsuan-Kai Huang, Hsuan-Kai Huang, , , | Summary: Transcranial photoacoustic computed tomography (PACT) is an emerging neuroimaging modality, but skull-induced aberrations can result in severe image artifacts if not compensated for during image reconstruction. The development of advanced image reconstruction methods for transcranial PACT is hindered […]

Sensorimotor Theta Oscillations Coordinate Speech Movements

Kavli Affiliate: Edward Chang and Loren Frank | Authors: Yitzhak Norman, Loren M. Frank and Edward F. Chang | Summary: Fluent speech depends on precisely timed motor commands that coordinate rapid transitions between successive articulatory gestures. Using direct cortical recordings, we identified a prominent sensorimotor theta oscillation (6–10 Hz) that supports this coordination. During articulation, […]
