Far-infrared Polarization Properties of Nearby Star-forming Regions: A New Compendium of SOFIA/HAWC+ Observations

Posted by klaurent Stanford

Kavli Affiliate: Susan Clark | Summary:We present a comprehensive polarimetric study of 26 nearby molecular clouds in four far-infrared bands (53 $μ$m to 214 $μ$m) using 52 archival SOFIA/HAWC+ datasets. Far-infrared dust polarization observations probe the plane-of-sky magnetic field. To investigate scale-dependent trends, we group the molecular clouds by distance and analyze the data at […]

Epicyclic Density Variations in the Indus Stellar Stream

Posted by klaurent Chicago

Kavli Affiliate: Alexander Ji | Summary:Longitudinal density fluctuations observed in stellar streams can result from gravitational interactions with massive perturbers in the Milky Way, such as dark matter subhalos. Analysing these density variations provides a powerful probe of properties (motion, mass, size, etc.) of the perturbing objects. However, caution is needed because density variations may […]

Mass Production of 2023 KMTNet Microlensing Planets I: Low Mass Ratio

Posted by klaurent Peking

Kavli Affiliate: Subo Dong | Summary:We initiate the systematic search for planets in the 2023 data of the Korea Microlensing Telescope Network (KMTNet), focusing on those planets found by the KMTNet AnomalyFinder with low preliminary estimates of the mass-ratio, $q<2times 10^-4$. The 2023 season is the first for which the photometry of all events was […]

HAWC J0630+186 Could Not Be Powered by PSR J0630+19

Posted by klaurent Peking

Kavli Affiliate: Renxin Xu | Summary:3HWC J0630+186 is one of the very-high-energy gamma-ray sources in the third High-Altitude Water Cherenkov (HAWC) catalog, its origin and source are, however, not clearly identified. The only possible associated source is PSR J0630+19 depart from the center of 3HWC J0630+186. A few TeV halos of pulsars are currently believed […]

Neuromuscular Signals Shape Fatigue and Effort-Based Decision-Making in Humans

Posted by dbos Hopkins

Kavli Affiliate: Vikram Chib | Authors: Agostina Casamento-Moran, Aram Kim, Joonhee Leo Lee and Vikram S. Chib | Summary: Physical fatigue influences our willingness to undertake effortful actions, yet the physiological signals driving this process are not well understood. We created a biofeedback paradigm to distinguish the effects of reduced muscle-force capacity from compensatory increases […]

Worlds Next Door. IV. Mapping the Late Stages of Giant Planet Evolution with a Precise Dynamical Mass and Luminosity for $ε$ Ind Ab

Posted by klaurent Caltech

Kavli Affiliate: Dimitri Mawet| Summary:We present new JWST/NIRCam 4-5 $μ$m (F410M, F430M) and JWST/MIRI 18-25 $μ$m (F1800W, F2100W, F2550W) imaging detections of the nearby (3.6 pc) cold (275 K) gas giant exoplanet $ε$ Ind Ab. The F2550W detection of $ε$ Ind Ab constitutes the longest wavelength image of an exoplanet acquired to date. Combining three […]

End-to-end optimisation of HEP triggers

Posted by klaurent Chicago

Kavli Affiliate: David W. Miller | Summary:High-energy physics experiments face extreme data rates, requiring real-time trigger systems to reduce event throughput while preserving sensitivity to rare processes. Trigger systems are typically constructed as modular chains of sequentially optimised algorithms, including machine learning models. Each algorithm is optimised for a specific local objective with no guarantee […]
