Kavli Affiliate: Anna Frebel | First 5 Authors: Ian U. Roederer, Timothy C. Beers, Kohei Hattori, Vinicius M. Placco, Terese T. Hansen | Summary: We present stellar parameters and chemical abundances of 47 elements detected in the bright (V = 11.63) very metal-poor ([Fe/H] = -2.20 +- 0.12) star 2MASS J22132050-5137385. We observed this star […]
Kavli Affiliate: Philip J. Marshall | First 5 Authors: Kenneth C. Wong, Frédéric Dux, Anowar J. Shajib, Sherry H. Suyu, Martin Millon | Summary: Time-delay cosmography is a powerful technique to constrain cosmological parameters, particularly the Hubble constant ($H_{0}$). The TDCOSMO collaboration is performing an ongoing analysis of lensed quasars to constrain cosmology using this […]

Kavli Affiliate: Yingjie Peng | First 5 Authors: Caro Derkenne, Richard M. McDermid, Francesco D’Eugenio, Caroline Foster, Aman Khalid | Summary: We use the `Middle Ages Galaxy Properties with Integral field spectroscopy’ (MAGPI) survey to investigate whether galaxies have evolved in the distribution of their stellar angular momentum in the past 3-4 Gyr, as probed […]
Kavli Affiliate: Wei Gao | First 5 Authors: Ruichao Yang, Wei Gao, Jing Ma, Hongzhan Lin, Bo Wang | Summary: Learning multi-task models for jointly detecting stance and verifying rumors poses challenges due to the need for training data of stance at post level and rumor veracity at claim level, which are difficult to obtain. […]
Kavli Affiliate: Xiang Zhang | First 5 Authors: Yinchuan Wang, Nianfei Du, Yongsen Qin, Xiang Zhang, Rui Song | Summary: It is challenging for the mobile robot to achieve autonomous and mapless navigation in the unknown environment with uneven terrain. In this study, we present a layered and systematic pipeline. At the local level, we […]

Kavli Affiliate: Jing Wang | First 5 Authors: Qiao-Chu Zhang, Jing Wang, , , | Summary: The effects of short-range fermion-fermion interactions on the low-energy properties of the rhombohedral trilayer graphene are comprehensively investigated by virtue of the momentum-shell renormalization group method. We take into account all one-loop corrections and establish the energy-dependent coupled evolutions […]
Kavli Affiliate: Zeeshan Ahmed | First 5 Authors: Thomas P. Satterthwaite, Zeeshan Ahmed, Kyuyoung Bae, Mark Devlin, Simon Dicker | Summary: The Simons Observatory is a new ground-based cosmic microwave background experiment, which is currently being commissioned in Chile’s Atacama Desert. During its survey, the observatory’s small aperture telescopes will map 10% of the sky […]
Kavli Affiliate: Yi Zhou | First 5 Authors: Yudan Wang, Yue Wang, Yi Zhou, Shaofeng Zou, | Summary: Actor-critic (AC) is a powerful method for learning an optimal policy in reinforcement learning, where the critic uses algorithms, e.g., temporal difference (TD) learning with function approximation, to evaluate the current policy and the actor updates the […]
