New probe of non-Gaussianities with primordial black hole induced gravitational waves

Posted by dbos Tokyo

Kavli Affiliate: Misao Sasaki | First 5 Authors: Theodoros Papanikolaou, Xin-Chen He, Xiao-Han Ma, Yi-Fu Cai, Emmanuel N. Saridakis | Summary: We propose a new probe of primordial non-Gaussianities (NGs) through the observation of gravitational waves (GWs) induced by ultra-light ($M_{text{PBH}}< 10^{9}rm{g}$) primordial black holes (PBHs). Interestingly enough, the existence of primordial NG can leave […]

VisRec: A Semi-Supervised Approach to Radio Interferometric Data Reconstruction

Posted by dbos Berkeley

Kavli Affiliate: Feng Wang | First 5 Authors: Ruoqi Wang, Haitao Wang, Qiong Luo, Feng Wang, Hejun Wu | Summary: Radio telescopes produce visibility data about celestial objects, but these data are sparse and noisy. As a result, images created on raw visibility data are of low quality. Recent studies have used deep learning models […]

Observational Evidence for Hot Wind Impact on pc-scale in Low-luminosity Active Galactic Nucleus

Posted by dbos Peking

Kavli Affiliate: Feng Yuan | First 5 Authors: Fangzheng Shi, Feng Yuan, Zhiyuan Li, Zhao Su, Suoqing Ji | Summary: Supermassive black holes in galaxies spend majority of their lifetime in the low-luminosity regime, powered by hot accretion flow. Strong winds launched from the hot accretion flow have the potential to play an important role […]

Surface Chern-Simons theory for third-order topological insulators and superconductors

Posted by dbos UCAS

Kavli Affiliate: Long Zhang | First 5 Authors: Zhi-Hao Huang, Yi Tan, Wei Jia, Long Zhang, Xiong-Jun Liu | Summary: Three-dimensional 3rd-order topological insulators (TOTIs) and superconductors (TOTSCs), as the highestorder topological phases hosting zero corner modes in physical dimension, has sparked extensive research interest. However, such topological states have not been discovered in reality […]
