Kavli Affiliate: Jia Liu | First 5 Authors: Haipeng An, Xingyao Chen, Shuailiang Ge, Jia Liu, Yan Luo | Summary: Ultralight dark photons and axions are well-motivated hypothetical dark matter candidates. Both dark photon dark matter and axion dark matter can resonantly convert into electromagnetic waves in the solar corona when their mass is equal […]
Kavli Affiliate: George Efstathiou | First 5 Authors: Harry T. J. Bevins, Stefan Heimersheim, Irene Abril-Cabezas, Anastasia Fialkov, Eloy de Lera Acedo | Summary: The first billion years of cosmic history remains largely unobserved. We demonstrate, using a novel machine learning technique, how combining upper limits on the spatial fluctuations in the 21-cm signal with […]
Kavli Affiliate: George Efstathiou | First 5 Authors: Harry T. J. Bevins, Stefan Heimersheim, Irene Abril-Cabezas, Anastasia Fialkov, Eloy de Lera Acedo | Summary: Observations of the first billion years of cosmic history are currently limited. We demonstrate, using a novel machine learning technique, the synergy between observations of the sky-averaged 21-cm signal from neutral […]
Kavli Affiliate: Wei Gao | First 5 Authors: Xiaohui Yan, Yue He, Xuncheng Liu, Siqi Jing, Jiajian Guan | Summary: The further development of fast electrochemical devices is hindered by self-discharge. Current strategies for suppressing self-discharge are mainly focused on the extrinsic and general mechanisms including faradaic reactions, charge redistribution, and ohmic leakage. However, the […]
Kavli Affiliate: Xiang Zhang | First 5 Authors: Tianxiang Zhao, Dongsheng Luo, Xiang Zhang, Suhang Wang, | Summary: Uncovering rationales behind predictions of graph neural networks (GNNs) has received increasing attention over recent years. Instance-level GNN explanation aims to discover critical input elements, like nodes or edges, that the target GNN relies upon for making […]
Kavli Affiliate: Joshua A. Frieman | First 5 Authors: Anowar J. Shajib, Pritom Mozumdar, Geoff C. -F. Chen, Tommaso Treu, Michele Cappellari | Summary: Strong-lensing time delays enable measurement of the Hubble constant ($H_{0}$) independently of other traditional methods. The main limitation to the precision of time-delay cosmography is mass-sheet degeneracy (MSD). Some of the […]

Kavli Affiliate: Damon Clark | Authors:Ryosuke Tanaka, Baohua Zhou, Margarida Agrochao, Bara A. Badwan, Braedyn Au, Natalia C. B. Matos and Damon A. Clark | Summary: In selecting a behavior, animals should weigh sensory evidence both for and against their beliefs about the world. For instance, animals use optic flow to estimate and control their […]
Kavli Affiliate: Bo Gu | First 5 Authors: Jia-Wen Li, Zhen Zhang, Jing-Yang You, Bo Gu, Gang Su | Summary: The two-dimensional (2D) van der Waals ferromagnetic semiconductors, such as CrI$_3$ and Cr$_2$Ge$_2$Te$_6$, and the 2D ferromagnetic metals, such as Fe$_3$GeTe$_2$ and MnSe$_2$, have been obtained in recent experiments and attracted a lot of attentions.
