Ab Initio Real-Time Gravitational-Wave Parameter Estimation
David Yallup, Metha Prathaban, James Alvey +4
We present a specialised GPU-native nested sampling kernel targeting rapid parameter estimation for gravitational wave inference problems. Building upon a Slice-within-Gibbs (SwiG)…
Impact of the Einstein Telescope's duty cycle on the estimation of binary black holes parameters
Luca Negri, Thomas C. K. Ng, Thibeau Wouters +13
The geometry of the Einstein Telescope, the proposed next-generation European gravitational-wave observatory, is yet to be finalized. Two competing designs are under consideration:…
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…
Inferring cosmology from gravitational waves using non-parametric detector-frame mass distribution
Thomas C. K. Ng, Stefano Rinaldi, Otto A. Hannuksela
The challenge of understanding the Universe's dynamics, particularly the Hubble tension, requires precise measurements of the Hubble constant. Building upon the existing spectral-s…
