Kavli Affiliate: Eric Miller | First 5 Authors: Xi Long, Xi Long, , , | Summary: We present results from the Chandra X-ray Observatory Large Project (878 ks in 28 observations) of the Large Magellanic Cloud supernova remnant N132D. We measure the expansion of the forward shock in the bright southern rim to be $0.!^primeprime10 […]
Kavli Affiliate: Laura Schaefer | First 5 Authors: Lichang Zhu, Lichang Zhu, , , | Summary: Predicting and interpreting thermal performance under oscillating flow in porous structures remains a critical challenge due to the complex coupling between fluid dynamics and geometric features. This study introduces a data-driven wGAN-LBM-Nested_CV framework that integrates generative deep learning, numerical […]
Kavli Affiliate: Lile Wang | First 5 Authors: Shuting Lin, Shuting Lin, , , | Summary: We report the discovery of a dense molecular ring-like structure in a dense (10$^5$ cm$^-3$), cold (pc-scale CO depletion at a factor of 5), and young (10$^4$ year) star-forming region G34.74-0.12, revealed by C$^18$O (2-1), HNC (1-0), and N$_2$H$^+$ […]
Kavli Affiliate: Zhuo Li | First 5 Authors: Yechen Zhang, Yechen Zhang, , , | Summary: Reinforcement learning (RL) has shown promise in a large number of robotic control tasks. Nevertheless, its deployment on unmanned aerial vehicles (UAVs) remains challenging, mainly because of reliance on accurate dynamic models and platform-specific sensing, which hinders cross-platform transfer. […]
Kavli Affiliate: George Efstathiou | First 5 Authors: Sudipta Sikder, Sudipta Sikder, , , | Summary: The 21-cm line of hydrogen is the most promising probe of the Dark Ages and Cosmic Dawn. We combine hydrodynamical simulations with a large-scale grid in order to calculate the effect of non-linear structure formation on the large-scale 21-cm […]
Kavli Affiliate: George Efstathiou | First 5 Authors: Hyunbae Park, Hyunbae Park, , , | Summary: It is thought that the Universe went through an early period known as the Dark Ages, during which primeval density fluctuations grew to form the first luminous objects, marking the beginning of Cosmic Dawn around 100 million years after […]
Kavli Affiliate: Lile Wang | First 5 Authors: Sheng Xu, Sheng Xu, , , | Summary: The inner regions of protoplanetary disks are host to the sublimation of dust grains, a process traditionally modeled using equilibrium thermodynamics. We demonstrate through ab-initio density functional theory (DFT) and kinetic Monte Carlo (KMC) simulations that silicate dust sublimation […]
Kavli Affiliate: Wendy L. Freedman | First 5 Authors: Mahdi Abdollahi, Mahdi Abdollahi, , , | Summary: The Period-Luminosity (PL) relation is usually derived using time-averaged magnitudes, which require multiple-epoch observations to determine periods and adequately sample the light curves. Although single-epoch observations are more practical and require significantly less observational effort, they inherently introduce […]
Kavli Affiliate: Sara Seager | First 5 Authors: Sukrit Ranjan, Sukrit Ranjan, , , | Summary: The James Webb Space Telescope (JWST) has begun to spectrally characterize small exoplanets orbiting M-dwarf stars, but interpretation of these spectra is ambiguous, with stellar, instrumental, or atmospheric origins possible for apparent spectral features. Consequently, interpretation of JWST small […]
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) […]
