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 […]

Kavli Affiliate: Jing Wang | First 5 Authors: Shun Wang, Jing Wang, Bi-Qing For, Bumhyun Lee, Tristan Reynolds | Summary: We study the tidal interaction of galaxies in the Eridanus supergroup, using HI data from the pre-pilot survey of WALLABY (Widefield ASKAP L-band Legacy All-sky Blind surveY). We obtain optical photometric measurements and quantify the […]
Kavli Affiliate: Feng Yuan | First 5 Authors: Fangzheng Shi, Bocheng Zhu, Zhiyuan Li, Feng Yuan, | Summary: Super-massive black holes (SMBHs) spend most of their lifetime accreting at a rate well below the Eddington limit, manifesting themselves as low-luminosity active galactic nuclei (LLAGNs). The prevalence of a hot wind from LLAGNs is a generic […]
Kavli Affiliate: Kohei Inayoshi | First 5 Authors: Daisuke Toyouchi, Kohei Inayoshi, Miho N. Ishigaki, Nozomu Tominaga, | Summary: Recent observations of active galactic nuclei (AGNs) have shown a high Fe~II/Mg~II line-flux ratio in their broad-line regions, nearly independent of redshift up to $z gtrsim 6$. The high flux ratio requires rapid production of iron […]
Kavli Affiliate: Xian Chen | First 5 Authors: Xian Chen, Yu Qiu, Shuo Li, F. K. Liu, | Summary: Extreme-mass-ratio inspirals (EMRIs) are important targets for future space-borne gravitational-wave (GW) detectors, such as the Laser Interferometer Sapce Antenna (LISA). Recent works suggest that EMRI may reside in a population of newly discovered X-ray transients called […]
Kavli Affiliate: Ran Wang | First 5 Authors: Yali Shao, Jeff Wagg, Ran Wang, Emmanuel Momjian, Chris L. Carilli | Summary: We present Karl G. Jansky Very Large Array (VLA) S- (2–4 GHz), C- (4–8 GHz), and X-band (8–12 GHz) continuum observations toward seven radio-loud quasars at $z>5$. This sample has previously been found to […]
Kavli Affiliate: Zhuo Li | First 5 Authors: Han-Ji Wu, Guo-Bin Mou, Kai Wang, Wei Wang, Zhuo Li | Summary: The origin of ultra-high energy neutrinos still lacks observational evidence, besides, the physical mechanism is also unclear. There is an association of a PeV neutrino event (IceCube-191001A) with an optical tidal disruption event (TDE, AT2019dsg) […]
