Kavli Affiliate: Hu Zhan | First 5 Authors: Zun Luo, Wei Du, Baocun Chen, Xianmin Meng, Hu Zhan | Summary: Precision measurements of astrometry and photometry require stringent control of systematics such as those arising from imperfect correction of sensor effects. In this work, we develop a parametric method to model the wavelength dependence of […]

In this work, we develop a parametric method to model the wavelength dependence of pixel response […]
Kavli Affiliate: Ke Wang | First 5 Authors: Fengwei Xu, Ke Wang, Tie Liu, David Eden, Xunchuan Liu | Summary: High-latitude ($|b|>30^{circ}$) molecular clouds have virial parameters that exceed 1, but whether these clouds can form stars has not been studied systematically. Using JCMT SCUBA-2 archival data, we surveyed 70 fields that target high-latitude Planck […]

Kavli Affiliate: Renxin Xu | First 5 Authors: Zhengli Wang, Jiguang Lu, Jingchen Jiang, Shunshun Cao, Weiyang Wang | Summary: Pulsar electrodynamics could be relevant to the physics of stellar surface, which remains poorly understood for more than half a centenary and is difficult to probe due to the absence of direct and clear observational […]
Kavli Affiliate: Zhuo Li | First 5 Authors: Butian Xiong, Zhuo Li, Zhen Li, , | Summary: We introduce a novel large-scale scene reconstruction benchmark using the newly developed 3D representation approach, Gaussian Splatting, on our expansive U-Scene dataset. U-Scene encompasses over one and a half square kilometres, featuring a comprehensive RGB dataset coupled with […]
Kavli Affiliate: Lijing Shao | First 5 Authors: Hai-Tian Wang, Lijing Shao, , , | Summary: Time-domain (TD) Bayesian inference is important in ringdown analysis for gravitational wave (GW) astronomy. The validity of this method has been well studied by Isi and Farr [1]. Using GW190521 as an example, we study the TD method in […]
Kavli Affiliate: Jing Wang | First 5 Authors: Zhaochen Liu, Jing Wang, , , | Summary: The quantum anomalous Hall (QAH) effect, first proposed by the Haldane model, has become a paradigmatic example of application of band topology to condensed matter physics. The recent experimental discoveries of high Chern number QAH effect in pentalayer and […]
Kavli Affiliate: Gregory J. Herczeg | First 5 Authors: Satoko Takahashi, Masahiro N. Machida, Mitsuki Omura, Doug Johnstone, Kazuya Saigo | Summary: We present ${sim}0.2$ arcsec ($sim$80 au) resolution observations of the CO (2-1) and SiO (5-4) lines made with the Atacama large millimeter/submillimeter array toward an extremely young intermediate-mass protostellar source (t$_{rm dyn}<$1000 years), […]
Kavli Affiliate: Gregory J. Herczeg | First 5 Authors: Seokho Lee, Jeong-Eun Lee, Doug Johnstone, Gregory J. Herczeg, Yuri Aikawa | Summary: We present the outflows detected in HOPS 373SW, a protostar undergoing a modest $30%$ brightness increase at 850 $mu$m. Atacama Large Millimeter/submillimeter Array (ALMA) observations of shock tracers, including SiO 8–7, CH$_3$OH 7$_{rm […]
