Kavli Affiliate: James Bock | Summary:In this paper, we describe the SPHEREx image and spectrophotometry data processing pipeline, an infrastructure and software system designed to produce calibrated spectral images and photometric measurements for NASA’s SPHEREx mission. SPHEREx is carrying out a series of four all-sky spectrophotometric surveys at 6.15 arcsecond resolution in 102 spectral channels […]
Kavli Affiliate: Eric Miller | Summary:We present new measurements of the chemical abundance pattern in the core of the nearby galaxy cluster Abell~2029, based on XRISM observations with Resolve (37 ks) and Xtend (500 ks), combined with archival data from XMM-Newton (EPIC, RGS) and Chandra. Fe abundances derived from Resolve, Xtend, and EPIC are broadly […]
Kavli Affiliate: Blake Sherwin | Summary:Over the last year, kinematic Sunyaev–Zel’dovich (kSZ) velocity reconstruction — the measurement of the large-scale velocity field using the anisotropic statistics of the small-scale kSZ-galaxy overdensity correlation — has emerged as a statistically significant probe of the large-scale Universe. In this work, we perform a 2-dimensional tomographic reconstruction using ACT […]
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:Foundation models have transformed machine learning for language and vision, but achieving comparable impact in physical simulation remains a challenge. Data heterogeneity and unstable long-term dynamics inhibit learning from sufficiently diverse dynamics, while varying resolutions and dimensionalities challenge efficient training on modern […]
Endothelial type I interferon signaling modulates the vascular response to ischemic brain injury Kavli Affiliate: Su Guo | Authors: Mathieu Daynac, Vincent Mouilleau, Yuxi Liu, Xiaoyu Yang, Yin Shen and Su Guo | Summary: Background Parkinson’s disease (PD) involves progressive loss of midbrain dopaminergic (mDA) neurons in the substantia nigra. No disease-modifying treatments exist, only […]
Kavli Affiliate: Giorgio Gratta | Summary:Off-axis parabolic mirrors (OAPs) are occasionally desirable for specialized applications, but are known to introduce field-dependent astigmatic aberrations. In an experiment where optical tweezers are formed by OAPs, another OAP is added to form a relay configuration with an optional microscope, resulting in near diffraction-limited performance, with a resolution of […]
Kavli Affiliate: Andrew Vanderburg | Summary:Despite the wide range of planet-star (mis)alignments in the mature population of transiting exoplanets, the small number of known young transiting planets are nearly all aligned with the rotation axes of their host stars, as determined by the sky-projected obliquity angle. The small number of young systems with measured obliquities […]
Kavli Affiliate: Susan Clark | Summary:Polycyclic aromatic hydrocarbon (PAH) emission is widely used to trace the distribution of molecular gas in the interstellar medium, exhibiting a tight correlation with CO(2-1) emission across nearby galaxies. Using PHANGS-JWST and PHANGS-ALMA data, we identify localized regions where this correlation fails, with CO flux exceeding that predicted from 7.7$μ$m […]

Endothelial type I interferon signaling modulates the vascular response to ischemic brain injury Kavli Affiliate: Kathleen Cullen | Authors: Chenhao Bao, Robyn Mildren, Adam Charles and Kathleen E Cullen | Summary: Background Complex spikes (CSs) in cerebellar Purkinje cells convey unique signals complementary to Simple spike (SS) action potentials, but are infrequent and variable in […]
