Apache Point Observatory follow-up of ACcelerating Candidate ExopLanet host Stars (APO ACCELS): Ages for 166 Accelerating Stars in the Northern Hemisphere

Posted by klaurent Stanford

Kavli Affiliate: Bruce Macintosh | First 5 Authors: Anne E. Peck, Anne E. Peck, , , | Summary: Directly imaged substellar companions with well-constrained ages and masses serve as vital empirical benchmarks for planet formation and evolution models. Potential benchmark companions can be identified from astrometric accelerations of their host stars. We use Gaia DR3 […]

Increasing single-photon production with cavity-QED

Posted by UCSB

Kavli Affiliate: John E. Bowers | First 5 Authors: Chen Shang, Weng W. Chow, Galan Moody, John E. Bowers, | Summary: A study was performed to determine the extent cavity enhancement may increase single-photon production while maintaining single-photon purity. It was found that certain combinations of cavity lifetime and light-matter coupling strength can lead to […]

Humans share acoustic preferences with other animals

Posted by dbos Columbia

Kavli Affiliate: Sarah Woolley | Authors: Logan S James, Sarah C Woolley, Jon T Sakata, Courtney B Hilton, Michael J Ryan and Samuel A Mehr | Summary: Many animals produce sounds during courtship, and receivers prefer some sounds over others. Shared ancestry and convergent evolution may generate similarities in preference across species and could underlie […]

TDCOSMO XXIII. First spatially resolved kinematics of the lens galaxy obtained using JWST-NIRSpec to improve time-delay cosmography

Posted by dbos Chicago

Kavli Affiliate: Joshua A. Frieman | First 5 Authors: Anowar J. Shajib, Tommaso Treu, Sherry H. Suyu, David Law, Akın Yıldırım | Summary: Spatially resolved stellar kinematics has become a key ingredient in time-delay cosmography to break the mass-sheet degeneracy in the mass profile and, in turn, provide a precise constraint on the Hubble constant […]

Mapping the projectional architecture of the mouse midbrain dopaminergic system using cell type-specific barcoding

Posted by dbos Hopkins

Kavli Affiliate: Justus M Kebschull | Authors: Hyopil Kim, Cheng Xu, Craig Washington, Maggie Lowmann and Justus M Kebschull | Summary: Brain-wide neural circuits are formed by the diverse axonal branching patterns of many individual neurons. Here we introduce POINTseq (projections of interest by sequencing), a high-throughput and user-friendly barcoded connectomics method that uses cell […]

Sifting for a Stream: The Morphology of the $300S$ Stellar Stream

Posted by dbos Chicago

Kavli Affiliate: Alexander P. Ji | First 5 Authors: Benjamin Cohen, Alexander P. Ji, Peter S. Ferguson, Sergey E. Koposov, Alex Drlica-Wagner | Summary: Stellar streams are sensitive laboratories for understanding the small-scale structure in our Galaxy’s gravitational field. Here, we analyze the morphology of the $300S$ stellar stream, which has an eccentric, retrograde orbit […]

High-quality metalens enables minimally invasive CFB endoscopy

Posted by klaurent Berkeley

Kavli Affiliate: Feng Wang | First 5 Authors: Ruixiang Song, Ruixiang Song, , , | Summary: Metalenses, owing to their ultra-thin planar structures, present a promising solution for reducing endoscopic invasiveness. However, achieving high-quality imaging with minimal invasiveness (short focal length of metalens) remains a critical challenge. This paper presents a deep learning assisted metalens […]

Modulating task outcome value to mitigate real-world procrastination via noninvasive brain stimulation

Posted by klaurent Berkeley

Kavli Affiliate: Ting Xu | First 5 Authors: Zhiyi Chen, Zhiyi Chen, , , | Summary: Procrastination represents one of the most prevalent behavioral problems affecting individual health and societal productivity. Although it is often conceptualized as a form of self-control failure, its underlying neurocognitive mechanisms are poorly understood. A leading model posits that procrastination […]

A Ground-Based Transit Observation of the Long-Period Extremely Low-Density Planet HIP 41378 f

Posted by klaurent MIT

Kavli Affiliate: Andrew Vanderburg | First 5 Authors: Juliana García-Mejía, Juliana García-Mejía, , , | Summary: We present a ground-based transit detection of HIP 41378 f, a long-period ($P = 542$ days), extremely low-density ($0.09 pm 0.02$ g cm$^-3$) giant exoplanet in a dynamically complex system. Using photometry from Tierras, TRAPPIST-North, and multiple LCOGT sites, […]
