Bright Siren Cosmology Beyond Fisher: DALI Forecasts for Third-Generation Gravitational Wave Observatories
Mayara H. Pacheco, Josiel M. S. de Souza, Odylio D. Aguiar +1
In this work we assess non-Gaussian extensions of Fisher forecasting based on the Derivative Approximation for Likelihoods (DALI). We simulate ensembles of bright siren catalogs fo…
Fisher and DALI posterior approximations for testing gravity with gravitational waves
Felipe A. da Silva Barbosa, Davi C. Rodrigues, Josiel Mendonça Soares de Souza +1
We investigate the accuracy and computational efficiency of posterior approximations for gravitational-wave (GW) parameter estimation based on Fisher Matrix and its higher-order ex…
GWDALI: A Fisher-matrix based software for gravitational wave parameter-estimation beyond Gaussian approximation
Josiel Mendonça Soares de Souza, Riccardo Sturani
We introduce GWDALI, a new Fisher-matrix, python based software that computes likelihood gradients to forecast parameter-estimation precision of arbitrary network of terrestrial gr…
Luminosity distance uncertainties from gravitational wave detections by third generation observatories
Josiel Mendonça Soares de Souza, Riccardo Sturani
A new generation of terrestrial gravitational wave detectors is currently being planned for the next decade, and it is expected to detect most of the coalescences of compact object…
Cosmography with Standard Sirens from the Einstein Telescope
Josiel Mendonça Soares de Souza, Riccardo Sturani, Jailson Alcaniz
We discuss the power of third-generation gravitational wave detectors to constrain cosmographic parameters in the case of electromagnetically bright standard sirens focusing on the…
Cosmological model selection from standard siren detections by third-generation gravitational wave obervatories
Josiel Mendonça, Riccardo Sturani
The multi-messenger observation of GW170817 enabled the first historic measurement of the Hubble constant via a standard siren, so-called in analogy to standard candles that enable…
