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 $0.!^primeprime10 […]
Kavli Affiliate: David A. Muller | First 5 Authors: Felix Bennemann, Felix Bennemann, , , | Summary: High-resolution transmission electron microscopy (HRTEM) is an important method for imaging beam sensitive materials often under cryo conditions. Electron ptychography in the scanning transmission electron microscope (STEM) has been shown to reconstruct low-noise phase data at a reduced […]
Kavli Affiliate: Laura Schaefer | First 5 Authors: Lichang Zhu, Lichang Zhu, , , | Summary: Predicting and interpreting thermal performance under oscillating flow in porous structures remains a critical challenge due to the complex coupling between fluid dynamics and geometric features. This study introduces a data-driven wGAN-LBM-Nested_CV framework that integrates generative deep learning, numerical […]
Kavli Affiliate: David Charbonneau | First 5 Authors: Samuel W. Yee, Samuel W. Yee, , , | Summary: The “Neptunian ridge” is a recently identified peak in the frequency of planets with sizes between that of Neptune and Saturn orbiting their host stars with periods between 3 and 6 days (A. Castro-Gonz’alez et al. 2024). […]
Kavli Affiliate: Lile Wang | First 5 Authors: Shuting Lin, Shuting Lin, , , | Summary: We report the discovery of a dense molecular ring-like structure in a dense (10$^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: Michael Shadlen | Authors: Prayshita Sharma, Michael Shadlen and S Shushruth | Summary: Perceptual decision-making refers to the class of decisions in which sensory evidence is used to categorize percepts and guide actions. Conventionally, categorical decisions are thought to precede motor actions. However, recent studies in nonhuman primates challenge this assumption — when […]
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 […]
