Gravitational wave Universe toolbox 引力波宇宙工具箱

As the importance of gravitational wave (GW) astrophysics increases rapidly, astronomers interested in GWs who are not experts in this field sometimes need to get a quick idea of what GW sources can be detected by certain detectors, and the accuracy of the measured parameters.

The GW-Toolbox is a set of easy-to-use, flexible tools to simulate observations of the GW universe with different detectors, including ground-based interferometers (advanced LIGO, advanced VIRGO, KAGRA, Einstein Telescope, Cosmic Explorer, and also customised interferometers), space-borne interferometers (LISA and a customised design), and pulsar timing arrays mimicking the current working arrays (EPTA, PPTA, NANOGrav, IPTA) and future ones. We include a broad range of sources, such as mergers of stellar-mass compact objects, namely black holes, neutron stars, and black hole-neutron star binaries, supermassive black hole binary mergers and inspirals, Galactic double white dwarfs in ultra-compact orbit, extreme-mass-ratio inspirals, and stochastic GW backgrounds.

In this talk, I will give a throughout overview of the toolbox, including its functionalities and methodology. I will also present two recent scientific application work done with the toolbox, namely the study on the future prospects of GW astronomy on binary black hole population and sub-threshold joint observation on binary neutron star mergers as GW sources and gamma-ray bursts.

Dr. Yi obtained his Ph.D of astrophysics from the University of Chinese Academy of Sciences in 2016. He did the research on theoretical aspects on compact binaries in Hong Kong University as a postdoctoral fellow in the following two years. From 2018 to 2021, Dr. Yi did his second postdoc in Radboud University gravitational wave research group, mainly focusing on GW astronomy, and enrolled in the Virgo and the LISA Science collaboration. From 2022, he joined the institute of high energy physics, CAS to study multi-messenger astronomy, combing high energy and GW observations. He also interested in astrophysical software development.
