Characterizing Pattern Matching and Its Limits on Compositional Task Structures

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:Despite impressive capabilities, LLMs’ successes often rely on pattern-matching behaviors, yet these are also linked to OOD generalization failures in compositional tasks. However, behavioral studies commonly employ task setups that allow multiple generalization sources (e.g., algebraic invariances, structural repetition), obscuring a precise […]

Enhanced magnetic activity in rapidly rotating binary stars

Kavli Affiliate: Robert Cameron | Summary:Stellar activity is fundamental to stellar evolution and the formation and habitability of exoplanets. The interaction between convective motions and rotation in cool stars results in a dynamo process that drives magnetic surface activity. In single stars, activity increases with rotation rate until it saturates for stars with rotation periods […]

Spontaneous generation of athermal phonon bursts within bulk silicon causing excess noise, low energy background events and quasiparticle poisoning in superconducting sensors

Kavli Affiliate: Roger Romani | Summary:Solid state phonon detectors used in the search for dark matter and coherent neutrino nucleus interactions (CE$ν$NS) require excellent energy resolution (eV-scale or below) and low backgrounds. An unknown source of phonon bursts, the low energy excess (LEE), dominates other above-threshold backgrounds and generates excess shot noise from sub-threshold bursts. […]

Origin of the X-ray emission in blazars through multiwavelength polarization

Kavli Affiliate: Roger W. Romani | First 5 Authors: Ioannis Liodakis, Haocheng Zhang, Stella Boula, Riccardo Middei, Jorge Otero-Santos | Summary: The origin of the high-energy emission in astrophysical jets from black holes is a highly debated issue. This is particularly true for jets from supermassive black holes that are among the most powerful particle […]

Plasticity as the Mirror of Empowerment

Kavli Affiliate: Tom Abel| First 5 Authors: David Abel, David Abel, , , | Summary:Agents are minimally entities that are influenced by their past observations and act to influence future observations. This latter capacity is captured by empowerment, which has served as a vital framing concept across artificial intelligence and cognitive science. This former capacity, […]

Roman Observations Time Allocation Committee: Final Report and Recommendations

Kavli Affiliate: Risa Wechsler | Summary:The Nancy Grace Roman Space Telescope is poised to revolutionize our scientific understanding of exoplanets, dark matter, dark energy, and general astrophysics, including through an innovative community approach to defining and executing sky surveys. The Roman Observations Time Allocation Committee (ROTAC) was convened to recommend time allocations for the three […]

EP241021a: a months-duration X-ray transient with luminous optical and radio emission

Kavli Affiliate: Paul Brink| First 5 Authors: Shu Xinwen, Shu Xinwen, , , | Summary:We present the discovery of a peculiar X-ray transient, EP241021a, by the Einstein Probe (EP) mission, and the results from multiwavelength follow-up observations. The transient was first detected with the Wide-field X-ray Telescope as an intense flare lasting for ~100 s, […]

The AGORA High-Resolution Galaxy Simulations Comparison Project VII: Satellite quenching in zoom-in simulation of a Milky Way-mass halo

Kavli Affiliate: Tom Abel | Summary:Context: Satellite galaxies experience multiple physical processes when interacting with their host halos, often leading to the quenching of star formation. In the Local Group (LG), satellite quenching has been shown to be highly efficient, affecting nearly all satellites except the most massive ones. While recent surveys are studying Milky […]

The {it AGORA} High-resolution Galaxy Simulations Comparison Project. VIII: Disk Formation and Evolution of Simulated Milky Way Mass Galaxy Progenitors at $1<z<5$

Kavli Affiliate: Tom Abel | First 5 Authors: Minyong Jung, Ji-hoon Kim, Thinh H. Nguyen, Ramon Rodriguez-Cardoso, Santi Roca-Fàbrega | Summary: We investigate how differences in the stellar feedback produce disks with different morphologies in Milky Way-like progenitors over 1 $leq z leq 5$, using eight state-of-the-art cosmological hydrodynamics simulation codes in the textit{AGORA} project.
