Kavli Affiliate: Feng Long| Summary: Kirigami turns stiff sheets into compliant, shape-morphing structures, but its reliance on periodic cut patterns comes at a cost: correlated panel rotations couple extension to shear, so stretching one axis drives a parasitic shear that cannot be suppressed, and also confine anisotropic stiffness to a narrow, discrete set of responses […]
Kavli Affiliate: Luis Ho | Summary:The 2021 Event Horizon Telescope observations resolve the innermost jet region of the blazar 3C279 with unprecedented detail. The reconstructed images consistently reveal a compact core elongated nearly orthogonal to the large-scale jet axis. This rarely observed morphology recurs across multiple epochs and from 22-230 GHz and is therefore intrinsic […]
Kavli Affiliate: Katrin Heitmann | Summary:Cosmology is a precision observational science, and large simulations are necessary components of many analyses. These simulations are computationally expensive and produce massive, complex datasets; sharing them widely — to enable further explorations, comparison with observations, and communication with general audiences — is crucial to realizing their scientific value. In […]
Kavli Affiliate: Katrin Heitmann | Summary:Cosmology is an observational precision science, and detailed and scientifically rich simulations are necessary components of many analyses. These simulations are often computationally expensive and produce massive amounts of complex data. Sharing that data widely to enable further explorations, comparison with observations, and communication with general audiences is crucial to […]
Kavli Affiliate: Shigeki Matsumoto | Summary:Although hidden-photon dark matter with masses above $10^-4,mathrmeV$ is well motivated by inflationary production, it remains largely unexplored by terrestrial experiments. Through kinetic mixing, hidden photons induce a weak oscillating electric field above $10,mathrmGHz$. We propose to amplify this signal using a compact high-frequency distributed cavity and detect it with […]
Kavli Affiliate: Moritz Guenther | Summary:Stars set the conditions for planet formation, planet evolution, and habitability — all major topics in astronomy today. Stars are also important in their own right as the most visible component of galaxies. In cool stars, X-ray emission is powered by magnetic fields, and so far our Sun is the […]
Kavli Affiliate: Vikram Chib | Authors: Aram Kim and Vikram S. Chib | Summary: Decisions to exert effort for reward are often conceptualized as reflecting a trade-off between anticipated benefits and effort costs. However, economic theories propose that valuation is reference-dependent, such that behavior is shaped relative to expected outcomes rather than absolute reward magnitude. […]
Kavli Affiliate: Risa Wechsler | Summary:James Webb Space Telescope (JWST) has discovered unexpectedly bright, rapidly growing galaxies in the early universe, which were not predicted by most previously existing galaxy formation models. Using synthetic JWST observations of the Azahar simulation suite, we show that comprehensive non-thermal physics ("Full-Physics") produces compact, self-regulated galaxies that match observations […]
Kavli Affiliate: Troy Porter | Summary:The thermal state of interstellar gas controls whether it remains warm and diffuse or cools into dense clouds. Twenty-one centimetre observations have established a statistical picture of neutral-gas phases, but their three-dimensional architecture has not previously been mapped. Here we present $mathcalP_rm 3D$, a three-dimensional reconstruction of thermal phase in […]
Kavli Affiliate: Debora Sijacki | Summary:JWST observations, which have pushed the discovery and characterization of galaxies to cosmic dawn, have revealed significant deficiencies in state-of-the-art galaxy formation simulations, motivating the need for novel, physically grounded models. We present the first results from the Azahar suite of ten high-resolution ($sim$20 pc), large-volume zoom-in cosmological simulations, which […]
