Testing cosmological isotropy with gravitational waves and gamma-ray bursts
Brian H. Y. Cheng, Donniel C. Cruz, Otto A. Hannuksela +18
The cosmological principle asserts that the Universe is homogeneous and isotropic on large enough scales. However, alternative cosmological models can bring about anisotropies thro…

Strong lensing cosmography using binary-black-hole mergers: Prospects for the near future
Koustav N. Maity, Souvik Jana, Tejaswi Venumadhav +2
A small fraction of gravitational-wave (GW) signals from binary black holes (BBHs) will be gravitationally lensed by intervening galaxies and galaxy clusters. Strong lensing will p…

Strong-lensing cosmography using third-generation gravitational-wave detectors
Souvik Jana, Shasvath J Kapadia, Tejaswi Venumadhav +2
We present a detailed exposition of a statistical method for estimating cosmological parameters from the observation of a large number of strongly lensed binary-black-hole (BBH) me…
