Kavli Affiliate: Kejia Lee | First 5 Authors: Wei-Yang Wang, Jin-Chen Jiang, Kejia Lee, Renxin Xu, Bing Zhang | Summary: Fast radio busts (FRBs) can exhibit a wide variety of polarisation properties, not only between sources but also from burst to burst for a same one. In this work, we revisit the polarisation characters of […]
Kavli Affiliate: Jing Wang | First 5 Authors: Jing Wang, HaiYing Wang, Shifeng Xiong, , | Summary: To tackle massive data, subsampling is a practical approach to select the more informative data points. However, when responses are expensive to measure, developing efficient subsampling schemes is challenging, and an optimal sampling approach under measurement constraints was […]
Kavli Affiliate: Ran Wang | First 5 Authors: Yuanqi Liu, Ran Wang, Emmanuel Momjian, Yingkang Zhang, Tao An | Summary: High-resolution imaging is crucial for exploring the origin and mechanism of radio emission in quasars, especially at high redshifts. We present 1.5 GHz Very Long Baseline Array (VLBA) images of the radio continuum emission from […]
Kavli Affiliate: Xian Chen | First 5 Authors: Zeyuan Xuan, Smadar Naoz, Xian Chen, , | Summary: Many gravitational wave (GW) sources in the LISA band are expected to have non-negligible eccentricity. Furthermore, many of them can undergo acceleration because they reside in the presence of a tertiary. Here we develop analytical and numerical methods […]
Kavli Affiliate: Feng Yuan | First 5 Authors: Fu-Guo Xie, Ramesh Narayan, Feng Yuan, , | Summary: An important parameter in the theory of hot accretion flows around black holes is $delta$, which describes the fraction of “viscously” dissipated energy in the accretion flow that directly heats the electrons. The radiative efficiency of a hot […]
Kavli Affiliate: Ke Wang | First 5 Authors: Ke Wang, Harshitha Machiraju, Oh-Hyeon Choung, Michael Herzog, Pascal Frossard | Summary: Convolutional neural networks (CNNs) have achieved superhuman performance in multiple vision tasks, especially image classification. However, unlike humans, CNNs leverage spurious features, such as background information to make decisions. This tendency creates different problems in […]
Kavli Affiliate: Kohei Inayoshi | First 5 Authors: Wenxiu Li, Kohei Inayoshi, Masafusa Onoue, Daisuke Toyouchi, | Summary: The early evolution of the quasar luminosity function (QLF) and black hole mass function (BHMF) encodes key information on the physics determining the radiative and accretion processes of supermassive black holes (BHs) in high-$z$ quasars. Although the […]

Kavli Affiliate: Renxin Xu | First 5 Authors: Xiaoyu Lai, Chengjun Xia, Renxin Xu, , | Summary: Our world is wonderful because of the normal but negligibly small baryonic part (i.e., atoms) although unknown dark matter and dark energy dominate the Universe. A stable atomic nucleus could be simply termed as “strong matter” since its […]
Kavli Affiliate: Subo Dong | First 5 Authors: Camille Landri, Ondřej Pejcha, Michał Pawlak, Andrzej Udalski, Jose L. Prieto | Summary: We present the analysis of existing optical photometry and new optical spectroscopy of the candidate cataclysmic variable star OGLE-BLG504.12.201843. As was shown previously, this object has an orbital period of 0.523419 days and exhibits […]
