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 […]

Inducing a Tunable Skyrmion-Antiskyrmion System through Ion Beam Modification of FeGe Films

Kavli Affiliate: David Muller | First 5 Authors: M. B. Venuti, Xiyue S. Zhang, Eric J Lang, Sadhvikas J. Addamane, Hanjong Paik | Summary: Skyrmions and antiskyrmions are nanoscale swirling textures of magnetic moments formed by chiral interactions between atomic spins in magnetic non-centrosymmetric materials and multilayer films with broken inversion symmetry. These quasiparticles are […]

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) […]
