Pulsar-wind-nebula-powered Galactic center X-ray filament G0.13-0.11: Proof of the synchrotron nature by IXPE

Posted by dbos MIT

Kavli Affiliate: Herman L. Marshall | First 5 Authors: Eugene Churazov, Ildar Khabibullin, Thibault Barnouin, Niccolò Bucciantini, Enrico Costa | Summary: We report the discovery of X-ray polarization from the X-ray-bright filament. G0.13-0.11 in the Galactic center (GC) region. This filament features a bright, hard X-ray source that is most plausibly a pulsar wind nebula […]

Interface-Induced Superconductivity in Magnetic Topological Insulator-Iron Chalcogenide Heterostructures

Posted by dbos Peking

Kavli Affiliate: Ke Wang | First 5 Authors: Hemian Yi, Yi-Fan Zhao, Ying-Ting Chan, Jiaqi Cai, Ruobing Mei | Summary: When two different electronic materials are brought together, the resultant interface often shows unexpected quantum phenomena, including interfacial superconductivity and Fu-Kane topological superconductivity (TSC). Here, we use molecular beam epitaxy (MBE) to synthesize heterostructures formed […]

A simple sensitivity analysis method for unmeasured confounders via linear programming with estimating equation constraints

Posted by dbos UCAS

Kavli Affiliate: Yi Zhou | First 5 Authors: Chengyao Tang, Yi Zhou, Ao Huang, Satoshi Hattori, | Summary: In estimating the average treatment effect in observational studies, the influence of confounders should be appropriately addressed. To this end, the propensity score is widely used. If the propensity scores are known for all the subjects, bias […]
