The Simons Observatory: Studies of Phase Drift in RF Transmission Lines from the First Large-Scale Deployment of Microwave Frequency Multiplexing for Cosmology

Posted by klaurent Stanford

Kavli Affiliate: Zeeshan Ahmed | First 5 Authors: Thomas P. Satterthwaite, Thomas P. Satterthwaite, , , | Summary: Fulfilling the science goals of the Simons Observatory, a state-of-the-art cosmic microwave background (CMB) experiment, has required deploying tens of thousands of superconducting bolometers. Reading out data from the observatory’s more than 67,000 transition-edge sensor (TES) detectors […]

Development Status of the KIPM Detector Consortium

Posted by klaurent Stanford

Kavli Affiliate: Noah Kurinsky | First 5 Authors: Dylan J Temples, Dylan J Temples, , , | Summary: A Kinetic Inductance Phonon-Mediated Detector is a calorimeter that uses kinetic inductance detectors to read out phonon signals from the device substrate. We have established a consortium comprising university and national lab groups dedicated to advancing the […]

Translation from Wearable PPG to 12-Lead ECG

Posted by klaurent Caltech

Kavli Affiliate: Wei Gao | First 5 Authors: Hui Ji, Hui Ji, , , | Summary: The 12-lead electrocardiogram (ECG) is the gold standard for cardiovascular monitoring, offering superior diagnostic granularity and specificity compared to photoplethysmography (PPG). However, existing 12-lead ECG systems rely on cumbersome multi-electrode setups, limiting sustained monitoring in ambulatory settings, while current […]

Ptbp1 is not required for retinal neurogenesis and cell fate specification.

Posted by dbos Hopkins

Kavli Affiliate: Seth Blackshaw | Authors: Haley Appel, Rogger Carmen-Orozco, Clayton Santiago, Thanh Hoang and Seth Blackshaw | Summary: The RNA-binding protein Ptbp1 has been proposed as a master regulator of neuronal fate, repressing neurogenesis through its effects on alternative splicing and miRNA maturation. While prior studies using RNA interference suggested that Ptbp1 loss promotes […]

Heisenberg Scaling in a Continuous-Wave Interferometer

Posted by klaurent MIT

Kavli Affiliate: Nergis Mavalvala | First 5 Authors: Hudson A. Loughlin, Hudson A. Loughlin, , , | Summary: Continuous-wave (CW) interferometry has stood at the frontier of precision measurement science since its inception, where it was used to search for the luminiferous ether, to the present day, where it forms the basis of interferometric gravitational-wave […]

The SAGA Survey. VI. The Size-Mass Relation for Low-Mass Galaxies Across Environments

Posted by klaurent Stanford

Kavli Affiliate: Risa H. Wechsler | First 5 Authors: Yasmeen Asali, Yasmeen Asali, , , | Summary: We investigate how Milky Way-like environments influence the sizes and structural properties of low-mass galaxies by comparing satellites of Milky Way analogs from the Satellites Around Galactic Analogs (SAGA) Survey with two control samples: an environmentally agnostic population […]

Untangling the Complex Nature of AGN Variability with Fairall 9

Posted by klaurent MIT

Kavli Affiliate: Erin Kara | First 5 Authors: Scott Hagen, Scott Hagen, , , | Summary: The accretion flow in AGN is not well understood, motivating intensive monitoring campaigns of multiwavelength variability to probe its structure. One of the best of these is the 3 year optical/UV/X-ray approximately daily monitoring campaign on Fairall,9, a fairly […]

Combined Exoplanet Mass and Atmospheric Characterization for Accelerated Exoplanetology

Posted by klaurent MIT

Kavli Affiliate: Sara Seager | First 5 Authors: Julien de Wit, Julien de Wit, , , | Summary: Today’s most detailed characterization of exoplanet atmospheres is accessible via transit spectroscopy (TS). Detecting transiting exoplanets only yields their size, and it is thus standard to measure a planet’s mass before moving towards their atmospheric characterization, or […]

The Accretion Disk Size Problem in AGN Disk Reverberation Mapping is an Obscuration Effect: A Uniform AGN Sample Study with Swift

Posted by klaurent MIT

Kavli Affiliate: Erin Kara | First 5 Authors: Collin Lewin, Collin Lewin, , , | Summary: In the past decade, Swift has performed several AGN high-cadence reverberation mapping campaigns, and generally found that the UV/optical interband lags are $sim$3 times longer than predicted for a standard thin disk, thus coined "the accretion disk size problem". […]

Triangle Splatting+: Differentiable Rendering with Opaque Triangles

Posted by klaurent UCAS

Kavli Affiliate: Yi Zhou | First 5 Authors: Jan Held, Jan Held, , , | Summary: Reconstructing 3D scenes and synthesizing novel views has seen rapid progress in recent years. Neural Radiance Fields demonstrated that continuous volumetric radiance fields can achieve high-quality image synthesis, but their long training and rendering times limit practicality. 3D Gaussian […]
