Kavli Affiliate: Anna Frebel | First 5 Authors: Jennifer Mead, Jennifer Mead, , , | Summary: Stellar surface abundances are records of the state of the gas from which stars formed, and thus trace how individual elements have mixed into the surrounding medium following their ejection from stars. In this work, we test the common […]
Kavli Affiliate: Yuji Tachikawa | First 5 Authors: Yuji Tachikawa, Yuji Tachikawa, , , | Summary: Strongly motivated by a mathematical result by Lin and Yamashita (arXiv:2412.02298), we describe a long exact sequence formed by groups of equivalence classes of two-dimensional $mathcalN=(0,1)$ supersymmetric quantum field theories (SQFTs) with and without $SU(2)$ symmetry. As an application, […]
Kavli Affiliate: Pau Amaro Seoane | First 5 Authors: Pau Amaro Seoane, Pau Amaro Seoane, , , | Summary: Stellar collisions in dense galactic nuclei might play an important role in fueling supermassive black holes (SMBHs) and shaping their environments. The gas released during these collisions can contribute to SMBH accretion, influencing phenomena such as […]
Kavli Affiliate: Masahito Yamazaki | First 5 Authors: Jun-ichi Sakamoto, Jun-ichi Sakamoto, , , | Summary: The four-dimensional Chern-Simons (CS) theory provides a systematic procedure for realizing two-dimensional integrable field theories. It is therefore a natural question to ask whether integrable deformations of the theories can be realized in the four-dimensional CS theory. In this […]

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 […]
