The Pre-Outburst Properties of the FU Ori Object HBC 722

Kavli Affiliate: Gregory Herczeg | Summary:FU Ori outbursts are thought to play an important role in stellar assembly and the evolution of protoplanetary disks. However, the progenitor young stellar objects are largely uncharacterized. We obtained a low-resolution optical spectrum of HBC 722 before its FU Ori outburst as part of a survey of young stellar […]

The AGORA High-resolution Galaxy Simulations Comparison Project. X: Formation and Evolution of Galaxies at the High-redshift Frontier

Kavli Affiliate: Tom Abel | Summary:Recent observations from JWST have revealed unexpectedly luminous galaxies, exhibiting stellar masses and luminosities significantly higher than predicted by theoretical models at Cosmic Dawn. In this study, we present a suite of cosmological zoom-in simulations targeting high-redshift ($z geq 10$) galaxies with dark matter halo masses in the range $10^10 […]

Mitigating effects of nonlinearities in homodyne quadrature interferometers

Kavli Affiliate: Johannes Lehmann | Summary:Homodyne Quadrature interferometers (HoQI) are an interferometric displacement sensing scheme proven to have excellent noise performance, making them a strong candidate for sensing and control schemes in gravitational wave detector seismic isolation. Like many interferometric schemes, HoQIs are prone to nonlinear effects when measuring displacements. These nonlinearities, if left unsuppressed, […]

Towards Aligning Multimodal LLMs with Human Experts: A Focus on Parent-Child Interaction

Kavli Affiliate: Hsiao-Mei (Sherry) Cho| First 5 Authors: [#item_custom_name[1, [#item_custom_name[2, [#item_custom_name[3, [#item_custom_name[4, [#item_custom_name[5| Summary:While multimodal large language models (MLLMs) are increasingly applied in human-centred AI systems, their ability to understand complex social interactions remains uncertain. We present an exploratory study on aligning MLLMs with speech-language pathologists (SLPs) in analysing joint attention in parent-child interactions, a […]

Many-body interferometry with semiconductor spins

Kavli Affiliate: Menno Veldhorst | Summary:Quantum simulators enable studies of many-body phenomena which are intractable with classical hardware. Spins in devices based on semiconductor quantum dots promise precise electrical control and scalability advantages, but accessing many-body phenomena has so far been restricted by challenges in nanofabrication and simultaneous control of multiple interactions. Here, we perform […]

Super amplification of lunar response to gravitational waves driven by thick crust

Kavli Affiliate: Xian Chen| Summary: The Moon has been long regarded as a natural resonator of gravitational waves (GWs) since 1960, showing great potential to fill the frequency gap left behind GW detections by ground- or space-based laser interferometry. However, the spatial variation of this amplification capacity on the Moon remains unclear. Here, we numerically […]

All-optical magnetization reversal via x-ray magnetic circular dichroism

Kavli Affiliate: Shigetaka Moriyama | First 5 Authors: Kihiro T. Yamada, Kihiro T. Yamada, , , | Summary: Light polarization is one of the most fundamental features, equivalent to energy and coherence. Magnetism changes light polarization, and vice versa. The irradiation of intense circularly polarized femtosecond pules to magnetic materials can alter the magnetic orders […]
