Revealing Impact of Critical Stellar Central Density on Galaxy Quenching through Cosmic Time

Kavli Affiliate: Yingjie Peng | First 5 Authors: Bingxiao Xu, Yingjie Peng, , , | Summary: In the previous work of Xu & Peng (2021), we investigated the structural and environmental dependence on quenching in the nearby universe. In this work we extend our investigations to higher redshifts by combining galaxies from SDSS and ZFOURGE […]

Impact of overlapping signals on parameterized post-Newtonian coefficients in tests of gravity

Kavli Affiliate: Lijing Shao | First 5 Authors: Yixuan Dang, Ziming Wang, Dicong Liang, Lijing Shao, | Summary: Gravitational waves have been instrumental in providing deep insights into the nature of gravity. Next-generation detectors, such as the Einstein Telescope, are predicted to have a higher detection rate given the increased sensitivity and lower cut-off frequency. […]

Language-guided Few-shot Semantic Segmentation

Kavli Affiliate: Jing Wang | First 5 Authors: Jing Wang, Yuang Liu, Qiang Zhou, Fan Wang, | Summary: Few-shot learning is a promising way for reducing the label cost in new categories adaptation with the guidance of a small, well labeled support set. But for few-shot semantic segmentation, the pixel-level annotations of support images are […]

Effect of Noise Estimation in Time-Domain Ringdown Analysis: A Case Study with GW150914

Kavli Affiliate: Lijing Shao | First 5 Authors: Hai-Tian Wang, Lijing Shao, , , | Summary: Accurate noise estimation from gravitational wave (GW) data is critical for Bayesian inference. However, recent studies on ringdown signal, such as those by Isi et al. [1], Cotesta et al. [2], and Isi and Farr [3], have encountered disagreement […]

Forecast of joint analysis of cosmic shear and supernovae magnification from CSST and LSST

Kavli Affiliate: Hu Zhan | First 5 Authors: Ye Cao, Bin Hu, Ji Yao, Hu Zhan, | Summary: Cosmic shear and cosmic magnification reflect the same gravitational lensing field. Each of these two probes are affected by different systematics. We study the auto- and cross-correlations of the cosmic shear from the China Space Survey Telescope […]

Narrow spectrum in repeating fast radio burst

Kavli Affiliate: Renxin Xu | First 5 Authors: Wei-Yang Wang, Yuan-Pei Yang, Hong-Bo Li, Jifeng Liu, Renxin Xu | Summary: Fast radio bursts (FRBs) can present narrow-band spectra with a variety of polarization properties. We study spectral properties from perspectives of intrinsic radiation mechanisms by invoking bunching mechanism and perturbations on charged bunches moving at […]
