Kavli Affiliate: Jing Wang | First 5 Authors: En-Ze Shao, Kai Liu, Hao Xie, Kaiqi Geng, Keke Bai | Summary: Metal chalcogenide is a promising material for studying novel underlying physical phenomena and nanoelectronics applications. Here, we systematically investigate the crystal structure and electronic properties of the AlSe surface alloy on Al (111) using scanning […]
Kavli Affiliate: Jing Wang | First 5 Authors: Kana Morokuma-Matsui, Kenji Bekki, Jing Wang, Paolo Serra, Yusei Koyama | Summary: We conduct a $^{12}$C$^{16}$O($J$=1-0) (hereafter CO) mapping survey of 64 galaxies in the Fornax cluster using the ALMA Morita array in cycle 5. CO emission is detected from 23 out of the 64 galaxies. Our […]
Kavli Affiliate: Ke Wang | First 5 Authors: Praveen Ravirathinam, Rahul Ghosh, Ke Wang, Keyang Xuan, Ankush Khandelwal | Summary: Creating separable representations via representation learning and clustering is critical in analyzing large unstructured datasets with only a few labels. Separable representations can lead to supervised models with better classification capabilities and additionally aid in […]
Kavli Affiliate: Luis C. Ho | First 5 Authors: Anuvab Banerjee, Vibhore Negi, Ravi Joshi, Nagendra Kumar, Paul J. Wiita | Summary: We investigate the possible presence of quasi-periodic oscillation (QPO) signals in 2103 blazars from the Zwicky Transient Facility (ZTF) time-domain survey. We detect a low-frequency QPO signal in five blazars observed over these […]
Kavli Affiliate: Claudio Ricci | First 5 Authors: Grisha Zeltyn, Benny Trakhtenbrot, Michael Eracleous, Jessie Runnoe, Jonathan R. Trump | Summary: We report the discovery of a new `changing-look’ active galactic nucleus (CLAGN) event, in the quasar SDSS J162829.17+432948.5 at z=0.2603, identified through repeat spectroscopy from the fifth Sloan Digital Sky Survey (SDSS-V). Optical photometry […]
Kavli Affiliate: Jing Wang | First 5 Authors: Maria Gordina, Tai Melcher, Jing Wang, , | Summary: We prove that a large deviations principle holds with a (good) natural rate function for sub-Riemannian random walks on homogeneous Carnot groups. | Search Query: ArXiv Query: search_query=au:”Jing Wang”&id_list=&start=0&max_results=10 Read More
Kavli Affiliate: Hu Zhan | First 5 Authors: Shi-Yu Li, Yun-Long Li, Tianmeng Zhang, Jozsef Vinko, Eniko Regos | Summary: The 2-m aperture Chinese Space Station Telescope (CSST), which observes at wavelengths ranging from 255 to 1000 nm, is expected to start science operations in 2024. An ultra-deep field observation program covering approximately 10 square […]
Kavli Affiliate: Lijing Shao | First 5 Authors: Leïla Haegel, Kellie O’Neal-Ault, Quentin G. Bailey, Jay D. Tasson, Malachy Bloom | Summary: An effective field theory framework, the Standard-Model Extension, is used to investigate the existence of Lorentz and CPT-violating effects during gravitational wave propagation. We implement a modified equation for the dispersion of gravitational […]
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 […]
