Kavli Affiliate: Taizan Watari | Summary:Sections 2–3 of this note were prepared primarily for the author’s private use, as a means of organizing the materials in (generally non-holomorphic) conformal field theory (CFT) on 2-dimensions in the language of the vertex operator algebra, and also of collecting subtle details. The choice of topics is intended to […]
Kavli Affiliate: Hsiaowen Chen |Summary:We introduce the QUEST Dwarfs program, which connects low-mass galaxies’ stellar populations, interstellar medium, and circumgalactic medium in a large and coherently analyzed sample using a combination of optical spectroscopy, broadband imaging, and FUV absorption spectra of bright background sources .We present initial results from the first-release sample, comprising 14 galaxies […]
Kavli Affiliate: Sara Seager | Summary:Helium is the second most abundant element in the Universe, yet helium-dominated atmospheres are rarely considered as environments for life. Two assumptions have contributed to this neglect: helium is expected to escape from rocky planets together with hydrogen, and Earth itself lacks a substantial helium envelope. Recent observations and atmospheric […]

Stenzel, Paul Park, Anthi Maslarinou, Evgenia Moschogianni, Allan Henrique Depieri Cataneo, Catherine A Freije, Yichen Zhou, Kenneth C Levenson, Corrine Quirk, Chenhui Zou, William Matthew Schneider, Adriano Aguzzi, Charles M Rice, Ype P De Jong and Eleftherios Michailidis | Summary: More than […]
Kavli Affiliate: Wei Gao| Summary:Multimodal signals, such as visual, audio, and tactile data, are increasingly maintained as persistent digital assets in immersive communication systems and digital twins. In these settings, the same multimodal content is repeatedly accessed by heterogeneous receivers with varying modality and bandwidth requirements. Existing compression and Joint Source-Channel Coding (JSCC) methods typically […]
Kavli Affiliate: Michael McDonald | Summary:We analyze new high-spectral resolution SITELLE observations (R = $λ/Δλ$ = 7000) of the filamentary nebula surrounding NGC 1275, central galaxy of the Perseus cluster. We present here analysis of the sii$lambda6716$ and sii$lambda6731$ emission line doublet, using its ratio to determine the electron density of the optically emitting filaments. […]
Kavli Affiliate: Dimitri Mawet| Summary:The Keck/NIRC2 infrared imager was upgraded in 2025 with dual-beam polarimetric observing modes spanning approximately 1.1–4.1 microns (JHKL’ bands). We present a preliminary JHK calibration of NIRC2 Polarimetry using a wavelength-dependent Mueller matrix model of the Keck tertiary mirror (M3), half-wave plate (HWP), image rotator (IMR), downstream optics, and Wollaston prism. […]
Kavli Affiliate: Li Zhao | Authors: Zhao Li, Aaron James and Shengxuan Li | Summary: Background Highly variable gene (HVG) selection begins almost every single-cell RNA-seq analysis. While ranking formulas have been compared extensively, the integer gene budget at which any ranking must be truncated is typically left to the user and habitually fixed near 2,000. […]

As a […]
Kavli Affiliate: Menno Witter | Authors: Daniel Reznik, Piotr Majka, Marcello GP Rosa, Menno P Witter and Christian F Doeller | Summary: The study of cross-species differences in the organization of the cerebral cortex received significant attention during the past century. However, the evolutionary principles governing changes in brain connectivity and their impact on cognition […]
