Progress toward a demonstration of high contrast imaging at ultraviolet wavelengths

Kavli Affiliate: Bruce Macintosh | First 5 Authors: Kyle Van Gorkom, Kyle Van Gorkom, , , | Summary: NASA’s Habitable Worlds Observatory (HWO) aims to achieve starlight suppression to the $10^-10$ level for the detection and spectral characterization of Earth-like exoplanets. Broadband ozone absorption features are key biosignatures that appear in the 200-400nm near-ultraviolet (UV) […]

Environmental vs. intrinsic quenching at cosmic noon: Predictions from cosmological hydrodynamical simulations for VLT-MOONRISE

Kavli Affiliate: Roberto Maiolino | First 5 Authors: Paul H. Goubert, Paul H. Goubert, , , | Summary: We present an investigation into the quenching of simulated galaxies across cosmic time, honing in on the role played by both intrinsic and environmental mechanisms at different epochs. In anticipation of VLT-MOONRISE, the first wide-field spectroscopic galaxy […]

Harnessing Uncertainty: Entropy-Modulated Policy Gradients for Long-Horizon LLM Agents

Kavli Affiliate: Ke Wang | First 5 Authors: Jiawei Wang, Jiawei Wang, , , | Summary: In long-horizon tasks, recent agents based on Large Language Models (LLMs) face a significant challenge that sparse, outcome-based rewards make it difficult to assign credit to intermediate steps. Previous methods mainly focus on creating dense reward signals to guide […]

R-parity violation and 8 TeV four-jet events at the LHC: a falsification opportunity for Wagner’s Rule

Kavli Affiliate: Carlos E. M. Wagner | First 5 Authors: Pedro Bittar, Pedro Bittar, , , | Summary: The CMS Collaboration at the Large Hadron Collider (LHC) has observed two four-jet events with a total invariant mass of about 8 TeV; within each event, the jets can be paired into two dijets with invariant masses […]

Superconformal symmetry in a class of Schellekens theories

Kavli Affiliate: Jeffrey A. Harvey | First 5 Authors: Harry Fosbinder-Elkins, Harry Fosbinder-Elkins, , , | Summary: In 2023, Moore and Singh used the theory of orbifold vertex operator algebras to explicitly construct an $mathcalN = 1$ supercurrent in the Beauty and the Beast module of Dixon, Ginsparg, and Harvey. Using their techniques, we show […]

Parity Violation in Galaxy Shapes: Primordial Non-Gaussianity

Kavli Affiliate: Eiichiro Komatsu | First 5 Authors: Toshiki Kurita, Toshiki Kurita, , , | Summary: We present a comprehensive study of galaxy intrinsic alignment (IA) as a probe of parity-violating primordial non-Gaussianity (PNG). Within the effective field theory (EFT) framework, we show that the parity-odd IA power spectrum is sensitive to the collapsed limit […]

Release and Recapture of Silica Nanoparticles from an Optical Trap in Weightlessness

Kavli Affiliate: Sven Herrmann | First 5 Authors: Govindarajan Prakash, Govindarajan Prakash, , , | Summary: Optically trapped Silica nanoparticles are a promising tool for precise sensing of gravitational or inertial forces and fundamental physics, including tests of quantum mechanics at ‘large’ mass scales. This field, called levitated optomechanics can greatly benefit from an application […]
