Serendipitous and targeted mm/sub-mm transient searches with wide-FOV telescope

Posted by klaurent Peking

Kavli Affiliate: Claudio Ricci | Summary:The millimeter/sub-millimeter (mm/sub-mm) sky remains a rich but under-explored frontier for transient and variable phenomena. A wide-field, high-sensitivity instrument with a large aperture and degree-scale field of view would open this regime, enabling both systematic survey monitoring and rapid-response follow-up. Key science opportunities include Galactic Plane monitoring and surveys to […]

Flexible gaze reinstatement during working memory for natural scenes

Posted by dbos UCSD / Salk

Kavli Affiliate: Anastasia Kiyonaga | Authors: Yueying Dong, Yunchen Hung, Lana Gaspariani and Anastasia Kiyonaga | Summary: The information we hold in mind with working memory (WM) may propagate beyond the cortex and out to the peripheral motor system. For instance, directionally biased hand and eye movements can express simple visuo-spatial features during WM maintenance. […]

Cold Gas Infall onto A Brightest Group Galaxy via A Gas-Rich Minor Merger

Posted by klaurent Peking

Kavli Affiliate: Jinyi Shangguan | Summary:Dust and cold gas are not uncommon in nearby early-type galaxies (ETGs), and represent an important aspect of their evolution. However, their origin has been debated for decades. Potential sources include internal processes (e.g., mass loss from evolved stars), external mechanisms (e.g., minor mergers or cooling flows), or a combination […]

Connection between galaxy morphology and dark-matter halo structure II: predicting disk structure from dark-matter halo properties

Posted by klaurent Peking

Kavli Affiliate: Luis Ho | Summary:We investigate how galactic disk structures connect to the detailed properties of their host dark-matter halos using the TNG50 simulation. From the hydrodynamic and matched dark-matter-only runs, we measure a comprehensive list of halo properties describing density structure, angular momentum, shape, assembly history, and environment. Using the morphological decomposition developed […]

Statistical properties of spicules in MURaM-ChE

Posted by klaurent Stanford

Kavli Affiliate: Robert Cameron | Summary:Numerical simulations of the solar chromosphere have progressed towards reproducing spicules, which are transient features observed at the solar limb using spectral lines such as H$α$, Ca II H&K, or Mg II h&k. Two types of spicules, referred to as types I and II, have been identified in observations and […]

Post-Training and Test-Time Scaling of Generative Agent Behavior Models for Interactive Autonomous Driving

Posted by klaurent Stanford

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:Learning interactive motion behaviors among multiple agents is a core challenge in autonomous driving. While imitation learning models generate realistic trajectories, they often inherit biases from datasets dominated by safe demonstrations, limiting robustness in safety-critical cases. Moreover, most studies rely on open-loop […]

Probing ground-state degeneracies of a strongly interacting Fermi-Hubbard model with superconducting correlations

Posted by klaurent Delft

Kavli Affiliate: Michael Wimmer | Summary:The Fermi-Hubbard model and its rich phase diagram naturally emerges as a description for a wide range of electronic systems. Recent advances in semiconductor-superconductor hybrid quantum dot arrays have allowed to realize degenerate quantum systems in a controllable way, e.g., allowing to observe robust zero-bias peaks in Kitaev chains, indicative […]

Kinematics of H I and O VI Absorbers: Insights into the Turbulence Driver of the Multiphase Circumgalactic Medium

Posted by klaurent Chicago

Kavli Affiliate: Hsiaowen Chen |Summary:We investigate large-scale gas kinematics in the multiphase circumgalactic medium (CGM) using the observed correlation between line width (Doppler $b$ parameter) and column density ($N$) for H I and O VI absorbers. Leveraging extensive public galaxy survey data at $zlesssim0.1$, we construct a new galaxy sample based on the availability of […]

Super-Eddington Accretion Geometry: a Remarkable Stability of the Hidden Ultraluminous X-Ray Source Cygnus X-3

Posted by klaurent MIT

Kavli Affiliate: Herman Marshall | Summary:We report on the average and orbital phase-resolved polarization of Cyg X-3 in the hard state during the 2023 Imaging X-ray Polarimetry Explorer (IXPE) observational campaign. We find the polarization degree of $ 21.2 pm 0.4 % $ and polarization angle of $ 92.2 pm 0.5^circ $, well compatible with […]
