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 […]

Narrow spectra of repeating fast radio bursts: A magnetospheric origin

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 a variety of polarization properties, and some of them have narrow spectra. We study spectral properties from perspectives of intrinsic radiation mechanisms and absorption during the waves propagating in […]

KMT-2023-BLG-1431Lb: A New $q < 10^{-4}$ Microlensing Planet from a Subtle Signature

Kavli Affiliate: Subo Dong | First 5 Authors: Aislyn Bell, Jiyuan Zhang, Youn Kil Jung, Jennifer C. Yee, Hongjing Yang | Summary: The current studies of microlensing planets are limited by small number statistics. Follow-up observations of high-magnification microlensing events can efficiently form a statistical planetary sample. Since 2020, the Korea Microlensing Telescope Network (KMTNet) […]

New limits on the local Lorentz invariance violation of gravity in the Standard-Model Extension with pulsars

Kavli Affiliate: Lijing Shao | First 5 Authors: Yiming Dong, Ziming Wang, Lijing Shao, , | Summary: Lorentz Invariance Violation (LIV) is posited as a possible relic effect of quantum gravity at low energy scales. The Standard-Model Extension provides an effective field-theoretic framework for examining possible deviations attributed to LIV. With the observations of the […]

Josephson Diode Effect in Topological Superconductor

Kavli Affiliate: Jing Wang | First 5 Authors: Zhaochen Liu, Linghao Huang, Jing Wang, , | Summary: We investigate the Josephson diode effect in topological Josephson junctions. We find that while a Josephson junction in the topological phase may exhibit higher diode efficiency compared to that in the trivial phase, this behavior is not universal. […]
