Kavli Affiliate: Jonathan Whitlock | Authors: Pearl Saldanha, Martin Bjerke, Benjamin Adric Dunn and Jonathan Robert Whitlock | Summary: Spatial navigation is commonly studied in static environments, but adaptive behavior frequently hinges on tracking moving goals in real time. Active pursuit exemplifies this challenge, since it is an inherently egocentric spatial behavior requiring continual localization […]
Kavli Affiliate: Salman Habib | Summary:Belief-propagation (BP) decoding for quantum low-density parity-check (QLDPC) codes is appealing due to its low complexity, yet it often exhibits convergence issues due to quantum degeneracy and short cycles that exist in the Tanner graph. To overcome this challenge, this paper proposes a reinforcement-learning (RL) approach that learns (offline) how […]
Kavli Affiliate: Adam Gazzaley | Authors: Andrew C Heusser, Tony J Simon, Esther Elliot, Christopher James, Adam Gazzaley and Nicole Gibson | Summary: Background Emotion regulation—the ability to respond to and restore equilibrium after emotional perturbations—is central to mental health. Yet objective measurement remains limited to lab-based studies with group-level results, while consumer wearables focus […]
Kavli Affiliate: Scott A. Hughes | Summary:We present new observations from JWST NIRCam that reveal a striking kpc-wide cavity in the stellar distribution of the central galaxy in the cluster Abell402. Supporting data from HST allow us to rule out extinction due to dust as an explanation and, instead, suggest that this is a localized […]
Kavli Affiliate: Richard Kessler | Summary:Observations of Type Ia supernovae (sne), which probe the late Universe, together with baryon acoustic oscillations (BAO) and the cosmic microwave background (CMB), which probe the intermediate and early epochs, provide complementary constraints on the expansion history of the Universe. In this work, we forecast constraints on dark energy and […]
Kavli Affiliate: Richard Kessler | Summary:Observations of Type Ia supernovae (SNIa), baryon acoustic oscillations (BAO), and the cosmic microwave background (CMB), which probe the late-, intermediate-, and early-universe epochs, respectively, provide complementary constraints on the expansion history of the Universe. In this work, we forecast constraints on dark energy and other extensions to the standard […]
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 […]
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 […]
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 […]
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 […]
