Windows to the goal: Pupillary working memory signatures prospectively adapt to task demands

Kavli Affiliate: Anastasia Kiyonaga | Authors: Yueying Dong, Yun-chen Hung, Connie Xie and Anastasia Kiyonaga | Summary: The pupillary light response was once considered a brainstem reflex, but newer findings indicate that pupil dilation can also reflect content held ‘in mind’ with working memory (WM). This suggests that WM may recruit even the earliest sensorimotor […]

Visualizing Millisecond Atomic Dynamics of Nanocrystals in Liquid

Kavli Affiliate: Paul Alivisatos | Summary:Atomic structures of nanomaterials are inherently dynamic, continuously reshaped through interactions with chemical species and external stimuli. Such dynamics are further amplified as the size and dimensionality of nanomaterials are reduced. Despite advances in analytical methods, it remains challenging to capture structural dynamics of nanomaterials in reactive environments with both […]

The background gas humming and multi-messenger transients of stalled supermassive black hole binaries

Kavli Affiliate: Pau Amaro Seoane | Summary:We establish the multi-messenger mechanics of episodic mass transfer in supermassive black hole binaries stalled within circumbinary discs. Utilizing continuous wavelet transforms, we isolate localized gas clumps at the cavity edge and track their evolution. By regularizing the forced fluid equations at Lindblad resonances via the inhomogeneous Airy differential […]

A Fast, Hot Wind from a Nuclear Starburst

Kavli Affiliate: Erin Kara | Summary:Galaxies with intense star formation often host multiphase, galaxy-scale winds powered by supernovae and fast stellar winds. These are strong enough to disrupt the star-forming interstellar medium, and they chemically enrich the surrounding circumgalactic medium. However, their launching mechanism remains unknown. Here we show that thermal gas pressure is sufficient […]

Analysis and control of Raman phonon dynamics for enhanced optical frequency conversion

Kavli Affiliate: Frank Wise | Summary:Raman phonons are quantized molecular motions that arise from the inelastic scattering of light and mediate a wide range of spectroscopic and nonlinear optical phenomena. These can play a major role in frequency-conversion processes, but commonly-used theoretical treatments based on the Raman gain spectrum largely neglect the phonons and their […]

Raman phonon dynamics and its control for enhanced optical frequency conversion

Kavli Affiliate: Frank Wise | Summary:Raman phonons arise from the inelastic scattering of light and represent quantized molecular motions that mediate a wide range of spectroscopic and nonlinear optical phenomena. In this work, we clarify the physical role of Raman phonons within a previously-developed time-domain framework based on the Raman-induced index modulation, and show that […]

RRAT J1541+4703: A Rotating Radio Transient Exhibiting Normal Pulsar States

Kavli Affiliate: Renxin Xu | Summary:Rotating Radio Transients (RRATs) are a class of pulsar-like objects characterized by intermittent radio emissions. Among them, RRATs that exhibit both RRAT and normal pulsar (NP) states may represent a key evolutionary stage from nulling pulsars to RRATs. We performed a detailed analysis of RRAT J1574+4703 using the Five-hundred-meter Aperture […]
