Normalizing Flows for Hierarchical Bayesian Analysis: A Gravitational Wave Population Study
David Ruhe, Kaze Wong, Miles Cranmer +1
We propose parameterizing the population distribution of the gravitational wave population modeling framework (Hierarchical Bayesian Analysis) with a normalizing flow. We first dem…
flowMC: Normalizing-flow enhanced sampling package for probabilistic inference in Jax
Kaze W. K. Wong, Marylou Gabrié, Daniel Foreman-Mackey
flowMC is a Python library for accelerated Markov Chain Monte Carlo (MCMC) leveraging deep generative modeling. It is built on top of the machine learning libraries JAX and Flax. A…
A Sun-like star orbiting a black hole
Kareem El-Badry, Hans-Walter Rix, Eliot Quataert +18
We report discovery of a bright, nearby () Sun-like star orbiting a dark object. We identified the system as a black hole candidate via its astrometri…
Nonlinear effects in black hole ringdown
Mark Ho-Yeuk Cheung, Vishal Baibhav, Emanuele Berti +8
We report evidence for nonlinear modes in the ringdown stage of the gravitational waveform produced by the merger of two comparable-mass black holes. We consider both the coalescen…
Automated discovery of interpretable gravitational-wave population models
Kaze W. K Wong, Miles Cranmer
We present an automatic approach to discover analytic population models for gravitational-wave (GW) events from data. As more gravitational-wave (GW) events are detected, flexible…
Backward Population Synthesis: Mapping the Evolutionary History of Gravitational-Wave Progenitors
Kaze W. K. Wong, Katelyn Breivik, Will M. Farr +1
One promising way to extract information about stellar astrophysics from gravitational wave catalogs is to compare the catalog to the outputs of stellar population synthesis modeli…
GRChombo: An adaptable numerical relativity code for fundamental physics
Tomas Andrade, Llibert Areste Salo, Josu C. Aurrekoetxea +29
GRChombo is an open-source code for performing Numerical Relativity time evolutions, built on top of the publicly available Chombo software for the solution of PDEs. Whilst GRChomb…
