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: 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: 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) […]
Kavli Affiliate: Jing Wang | First 5 Authors: Yunfei Teng, Jing Wang, Anna Choromanska, , | Summary: Modern deep learning (DL) architectures are trained using variants of the SGD algorithm that is run with a $textit{manually}$ defined learning rate schedule, i.e., the learning rate is dropped at the pre-defined epochs, typically when the training loss […]
Kavli Affiliate: Ran Wang | First 5 Authors: Su Yao, Xiaolong Yang, Minfeng Gu, Tao An, Jun Yang | Summary: The jet in active galactic nuclei (AGN) is a key ingredient in understanding the co-evolution of galaxies and their central supermassive black holes (SMBHs). Unfortunately, the mechanism of jet launching and collimation is still elusive. […]
Kavli Affiliate: Luis C. Ho | First 5 Authors: Zhifu Chen, Zhicheng He, Luis C. Ho, Qiusheng Gu, Tinggui Wang | Summary: Both theory and observations suggest that outflows driven by an active central supermassive black hole (SMBH) has a feedback effect on shaping the global properties of the host galaxy. However, whether feedback from […]
Kavli Affiliate: Jing Wang | First 5 Authors: Yang Li, Jing Wang, Hai-Qing Lin, Lei Shao, | Summary: Bio-compatible Au nanoparticles exhibit great advantages in the application of biomedical researches, such as bio-sensing, medical diagnosis, and cancer therapy. Bio-molecules can even be manipulated by laser tweezers with the optically trapped Au nanoparticles as handles. In […]
