Kavli Affiliate: Renxin Xu | First 5 Authors: Hua Feng, Hong Li, Xiangyun Long, Ronaldo Bellazzini, Enrico Costa | Summary: The Crab nebula is so far the only celestial object with a statistically significant detection in soft x-ray polarimetry, a window that has not been explored in astronomy since the 1970s. However, soft x-ray polarimetry […]
Kavli Affiliate: Renxin Xu | First 5 Authors: Shi Dai, Jiguang Lu, Chen Wang, Weiyang Wang, Renxin Xu | Summary: Fast spinning (e.g., sub-second) neutron star with ultra-strong magnetic fields (or so-called magnetar) is one of the promising origins of repeating fast radio bursts (FRBs). Here we discuss circularly polarised emissions produced by propagation effects […]
Kavli Affiliate: Renxin Xu | First 5 Authors: Weihua Wang, Xiaoyu Lai, Enping Zhou, Jiguang Lu, Xiaoping Zheng | Summary: Glitch is supposed to be a useful probe into pulsar’s interior, but the underlying physics remains puzzling. The glitch activity may reflect a lower limit of the crustal moment of inertia in conventional neutron star […]
Kavli Affiliate: Pau Amaro Seoane | First 5 Authors: Alejandro Torres-Orjuela, Pau Amaro Seoane, Zeyuan Xuan, Alvin J. K. Chua, María J. B. Rosell | Summary: Gravitational waves from a source moving relative to us can suffer from special-relativistic effects such as aberration. The required velocities for these to be significant are on the order […]
Kavli Affiliate: Claudio Ricci | First 5 Authors: Hyunsung D. Jun, Roberto J. Assef, Christopher M. Carroll, Ryan C. Hickox, Yonghwi Kim | Summary: The absence of high Eddington ratio, obscured Active Galactic Nuclei (AGN) in local ($zlesssim0.1$) samples of moderate luminosity AGN has generally been explained to result from radiation pressure on the dusty […]
Kavli Affiliate: Pau Amaro Seoane | First 5 Authors: Kostas Tzanavaris, Pau Amaro Seoane, , , | Summary: In the context of mathematical cosmology, the study of necessary and sufficient conditions for a semi-Riemannian manifold to be a (generalised) Robertson-Walker space-time is important. In particular, it is a requirement for the development of initial data […]
Kavli Affiliate: Ke Wang | First 5 Authors: Zhenlong Xu, Ziqi Xu, Jixue Liu, Debo Cheng, Jiuyong Li | Summary: The increasing application of machine learning techniques in everyday decision-making processes has brought concerns about the fairness of algorithmic decision-making. This paper concerns the problem of collider bias which produces spurious associations in fairness assessment […]
Kavli Affiliate: Gregory J. Herczeg | First 5 Authors: Camilo González-Ruilova, Lucas A. Cieza, Antonio S. Hales, Sebastián Pérez, Alice Zurlo | Summary: ISO-Oph 2 is a wide-separation (240 au) binary system where the primary star harbors a massive (M$_{dust}$ $sim$40 M$_{oplus}$) ring-like disk with a dust cavity $sim$50 au in radius and the secondary […]
Kavli Affiliate: Yingjie Peng | First 5 Authors: Jing Dou, Yingjie Peng, Alvio Renzini, Luis C. Ho, Filippo Mannucci | Summary: Star formation and quenching are two of the most important processes in galaxy formation and evolution. We explore in the local Universe the interrelationships among key integrated galaxy properties, including stellar mass $M_*$, star […]
Kavli Affiliate: Gregory Herczeg | First 5 Authors: Logan Francis, Doug Johnstone, Gregory Herczeg, Todd R. Hunter, Daniel Harsono | Summary: A diverse array of science goals require accurate flux calibration of observations with the Atacama Large Millimeter/Submillimeter array (ALMA), however, this goal remains challenging due to the stochastic time-variability of the “grid” quasars ALMA […]
