Kavli Affiliate: Xian Chen | First 5 Authors: Zucheng Gao, Xian Chen, Yi-Ming Hu, Jian-Dong Zhang, Shunjia Huang | Summary: Gravitational lensing of gravitational waves (GWs) is a powerful probe of the matter distribution in the universe. Here we revisit the wave-optics effects induced by dark matter (DM) halos on the GW signals of merging […]
Kavli Affiliate: Subo Dong | First 5 Authors: S. J. Brennan, M. Fraser, J. Johansson, A. Pastorello, R. Kotak | Summary: We present the results from a high cadence, multi-wavelength observation campaign of AT 2016jbu (aka Gaia16cfr), an interacting transient. This dataset complements the current literature by adding higher cadence as well as extended coverage […]
Kavli Affiliate: Zhuo Li | First 5 Authors: Zhuo Li, Weiqing Min, Jiajun Song, Yaohui Zhu, Liping Kang | Summary: Optimising the approximation of Average Precision (AP) has been widely studied for image retrieval. Limited by the definition of AP, such methods consider both negative and positive instances ranking before each positive instance. However, we […]
Kavli Affiliate: Ke Wang | First 5 Authors: Yu Wang, Ke Wang, Linzhang Wang, , | Summary: Attribution methods have emerged as a popular approach to interpreting model predictions based on the relevance of input features. Although the feature importance ranking can provide insights of how models arrive at a prediction from a raw input, […]
Kavli Affiliate: Gregory J. Herczeg | First 5 Authors: Jamila Pegues, Ian Czekala, Sean M. Andrews, Karin I. Öberg, Gregory J. Herczeg | Summary: In this era of Gaia and ALMA, dynamical stellar mass measurements provide benchmarks that are independent of observations of stellar characteristics and their uncertainties. These benchmarks can then be used to […]
Kavli Affiliate: Ran Wang | First 5 Authors: Ran Wang, Yimin Xiao, , , | Summary: The generalized fractional Brownian motion (GFBM) $X:={X(t)}_{tge0}$ with parameters $gamma in [0, 1)$ and $alphain left(-frac12+frac{gamma}{2}, , frac12+frac{gamma}{2} right)$ is a centered Gaussian $H$-self-similar process introduced by Pang and Taqqu (2019) as the scaling limit of power-law shot noise […]
Kavli Affiliate: Gregory J. Herczeg | First 5 Authors: Chun-Fan Liu, Hsien Shang, Gregory J. Herczeg, Frederick M. Walter, | Summary: Forbidden neon emission lines from small-scale microjets can probe high-energy processes in low-mass young stellar systems. We obtained spatially resolved [Ne III] spectra of the microjets from the classical T Tauri Star Sz 102 […]
Kavli Affiliate: Gregory J. Herczeg | First 5 Authors: Anupam Bhardwaj, Marina Rejkuba, Richard de Grijs, Soung-Chul Yang, Gregory J. Herczeg | Summary: We present new near-infrared, $JHK_s$, Period–Luminosity relations (PLRs) for RR Lyrae variables in the Messier 53 (M53 or NGC 5024) globular cluster. Multi-epoch $JHK_s$ observations, obtained with the WIRCam instrument on the […]
Kavli Affiliate: Fukun Liu | First 5 Authors: Xinwen Shu, Wenjie Zhang, Shuo Li, Ning Jiang, Liming Dou | Summary: Optical transient surveys have led to the discovery of dozens of stellar tidal disruption events (TDEs) by massive black hole in the centers of galaxies. Despite extensive searches, X-ray follow-up observations have produced no or […]
