A Consistent Implementation of Cluster Strong Lensing in Cosmological Simulation Light Cones

Posted by klaurent May 28, 2026MIT

Kavli Affiliate: Michael McDonald | Summary:Galaxy cluster strong gravitational lensing plays a central role in precision cosmology, yet robust theoretical predictions have lagged behind an abundance of high-quality strong lensing observations. This shortfall reflects both a mismatch between the geometry of the strong-lensing problem and standard cubic simulation boxes, and the fundamental tension between simulation […]

Visuomotor flexibility is embedded in the topography of frontal cortex

Posted by dbos May 28, 2026June 9, 2026UCSD / Salk

Kavli Affiliate: John Reynolds | Authors: Nicholas M Dotson and John H Reynolds | Summary: Visual selection and saccade targeting are not obligatorily coupled, allowing a stimulus at one location to guide an eye movement toward another. This is mediated by frontal oculomotor cortex, where maps of visual and motor space converge, yet whether the […]

Efficient computation of the galaxy angular bispectrum in redshift space

Posted by klaurent May 28, 2026Cambridge

Kavli Affiliate: Anthony Challinor | Summary:Efficient computation of the angular bispectrum is an essential part of modelling large-scale structure observations, but it still remains an extremely challenging task. In this work, we compute the tree-level, unequal-time angular bispectrum in both real and redshift space. By deriving full-sky results, we show that the bispectrum can be […]

An archival summary: 15 years of ALMA observations on disks and planet formation

Posted by klaurent May 28, 2026June 9, 2026Peking

Kavli Affiliate: Feng Long| Summary: The Atacama Large (sub-)millimeter Array (ALMA) has been in scientific operations for almost 15 years. We celebrate this achievement by providing a summary of the “Disks and planet formation” scientific category, with an emphasis on the disks located in the nearby star-forming regions. As of the beginning of February 2026, […]

High-S/N Quasar Observations with HST/COS: Deep Fields for Spectroscopy

Posted by klaurent May 28, 2026June 9, 2026Chicago

Kavli Affiliate: Hsiaowen Chen |Summary:Hubble is still in prime observing condition for making transformative discoveries in UV astronomy. In this white paper we describe the science case for a deep (S/N>30) UV spectroscopic survey with HST/COS targeting approximately 20 QSOs at 0.5<z<1.5 at good resolution (20 km/s). This survey would capitalize on our current UV […]

Transient Signatures of Star-Envelope Collisions in Little Red Dots

Posted by klaurent May 28, 2026Peking

Kavli Affiliate: Kohei Inayoshi | Summary:Little red dots (LRDs) are compact high-redshift objects, newly discovered by the James Webb Space Telescope. Although LRDs exhibit broad Balmer emission lines suggestive of the presence of active galactic nuclei (AGN), their spectral features differ significantly from those of ordinary AGN. Recent studies suggest that their characteristics can be […]

High-Quality Axion Dark Matter without Isocurvature Problem

Posted by klaurent May 28, 2026Tokyo

Kavli Affiliate: Masahiro Kawasaki | Summary:Axion dark matter in high-scale inflation is subject to the isocurvature constraint, since quantum fluctuations of the axion field during inflation may exceed the current CMB bound. One conventional way to suppress these fluctuations is to assume that the Peccei-Quinn field has a large expectation value during inflation. However, this […]
