A follow-up strategy enabling discovery of electromagnetic counterparts to highly magnified gravitationally lensed gravitational waves [0.03%] 一种能够发现被引力透镜效应放大的引力波事件的电磁对应体的后续观测策略
Dan Ryczanowski,Jeff Cooke,James Freeburn et al. Dan Ryczanowski et al.
Making an unambiguous detection of lensed gravitational waves (GWs) is challenging with current-generation detectors due to large uncertainties in sky localizations and other inferred parameter distributions. However, in the case of binary ...

General relativity (GW) postulates that gravitational waves, like light, can be gravitationally lensed by intervening massive astrophysical objects, such as galaxies, black holes and stars. The gravitational lensing effect could magnify, sp...
Kilonova simulations: connecting observations with the underlying physics [0.03%] 千新星模拟：观测与物理本质之间的联系
Christine Collins,Luke Shingles,Vimal Vijayan Christine Collins
Kilonova observations contain information about heavy-element r-process nucleosynthesis and the behaviour of high-density matter. However, interpreting what these observations tell us about the underlying physics requires detailed modelling...
Challenges and opportunities for time-delay cosmography with multi-messenger gravitational lensing [0.03%] 时延引力透镜多信使宇宙学面临的挑战与机遇
Simon Birrer,Graham P Smith,Anowar J Shajib et al. Simon Birrer et al.
Strong gravitational lensing of variable sources, such as quasars or supernovae, can be used to constrain cosmological parameters through a technique known as 'time-delay cosmography'. Competitive constraints on the Hubble constant have bee...

We introduce the rapidly emerging field of multi-messenger gravitational lensing-the discovery and science of gravitationally lensed phenomena in the distant universe through the combination of multiple messengers. This is framed by gravita...

The next generation of gravitational wave (GW) detectors and electromagnetic telescopes are beckoning the onset of the multi-messenger era and the exciting science that lies ahead. Multi-messenger strong gravitational lensing will help prob...
Strong gravitational lenses from the Vera C. Rubin Observatory [0.03%] 运用Vera C. Rubin天文台观测的强引力透镜现象研究
Anowar J Shajib,Graham P Smith,Simon Birrer et al. Anowar J Shajib et al.
Like many areas of astrophysics and cosmology, the Vera C. Rubin Observatory will be transformational for almost all the applications of strong lensing, thanks to the dramatic increase in the number of known strong lenses by two orders of m...
False positives for gravitational lensing: the gravitational-wave perspective [0.03%] 引力波视角下的引力透镜假阳性事件

For the first detection of a novel astrophysical phenomenon, scientific standards are particularly high. Especially in a multi-messenger context, there are also opportunity costs to follow-up observations on any detection claims. So in sear...

A rather clear problem has remained for astrophysicists studying black holes: localizing black holes. One of the recent theoretical ways proposed to identify black hole mergers' hosts is through multi-messenger gravitational lensing: matchi...
