Kavli Affiliate: Yingjie Peng | First 5 Authors: Joanna M. Piotrowska, Asa F. L. Bluck, Roberto Maiolino, Yingjie Peng, | Summary: In this paper we investigate how massive central galaxies cease their star formation by comparing theoretical predictions from cosmological simulations: EAGLE, Illustris and IllustrisTNG with observations of the local Universe from the Sloan Digital […]

Kavli Affiliate: Yingjie Peng | First 5 Authors: Rui Shi, Wenting Wang, Zhaozhou Li, Jiaxin Han, Jingjing Shi | Summary: We propose a random forest (RF) machine learning approach to determine the accreted stellar mass fractions ($f_mathrm{acc}$) of central galaxies, based on various dark matter halo and galaxy features. The RF is trained and tested […]

Kavli Affiliate: Zhuo Li | First 5 Authors: Zhuo Li, , , , | Summary: Capturing long-range dependency and modeling long temporal contexts is proven to benefit speaker verification tasks. In this paper, we propose the combination of the Hierarchical-Split block(HS-block) and the Depthwise Separable Self-Attention(DSSA) module to capture richer multi-range context speaker features from […]

Kavli Affiliate: Jing Wang | First 5 Authors: Kai Liu, Keke Bai, Jing Wang, Juntao Song, Ying Liu | Summary: Antimonene is a novel two-dimensional topological semiconductor material with strain driven tunable electronic structure for future electronic and spintronic devices, but the growth of clean antimonene is not fully understood. In this work, the growth […]

Kavli Affiliate: Renxin Xu | First 5 Authors: Wei-Yang Wang, Jin-Chen Jiang, Jiguang Lu, Heng Xu, Jiangwei Xu | Summary: Fast radio bursts (FRBs) are millisecond-duration signals, to be highly dispersed at distant galaxies, the physical origin of which is still challenging. Coherent curvature emission by bunches powered, e.g., by starquakes, has already been proposed […]
