Impact of sky localization uncertainty on ringdown inference
Kallol Dey, Enrico Barausse, Marco Crisostomi +1
As gravitational-wave ringdown signals grow louder, quasinormal-mode inference depends increasingly on the treatment of extrinsic parameters. Standard analyses fix sky localization…
Reconstructing the LISA massive black hole binary population via iterative kernel density estimation
Jam Sadiq, Kallol Dey, Thomas Dent +1
Reconstructing the properties of the astrophysical population of binary compact objects in the universe is a key science goal of gravitational wave detectors. This goal is hindered…
Neural Posterior Estimation with guaranteed exact coverage: the ringdown of GW150914
Marco Crisostomi, Kallol Dey, Enrico Barausse +1
We analyze the ringdown phase of the first detected black-hole merger, GW150914, using a simulation-based inference pipeline based on masked autoregressive flows. We obtain approxi…
Measuring deviations from the Kerr geometry with black hole ringdown
Kallol Dey, Enrico Barausse, Soumen Basak
Black holes in General Relativity are famously characterized by two "hairs" only, the mass and the spin of the Kerr spacetime. Theories extending General Relativity, however, allow…
Effect of data gaps on the detectability and parameter estimation of massive black hole binaries with LISA
Kallol Dey, Nikolaos Karnesis, Alexandre Toubiana +4
Massive black hole binaries are expected to provide the strongest gravitational wave signals for the Laser Interferometer Space Antenna (LISA), a space mission targeting mH…
