Gravitational Wave Toolbox

Speaker:Dr. Shuxu Yi
Affiliation:Department of Astrophysics, Radboud University Nijmegen, the Netherlands
Date:April 23, 2019 (Tuesday)
Time:11:00 a.m.
Venue:Room 105, 1/F, Chong Yuet Ming Physics Building, HKU


The discoveries by LIGO and Virgo bring the world into the gravitational wave astronomy era. In the near further, new GW observatories will spring up: on the ground, there will be AIGO, LIGO-India, KAGRA, Einstein telescope and Cosmic Explore; in the space, there comes eLISA and Tianqin; Besides, there are pulsar timing arrays searching for the ultra-low frequency gravitational waves. More and more astronomers, from all backgrounds, need to understand the functionalities of different GW observatories. More specifically, they will hope to know the answers for the following questions: "what sources are expected to be detected by a certain GW observatory? How many of them will be detected given a certain observing time, and what will be the distribution of physical parameters of the population? What will the electromagnetic wave counter parts look like?"

Scientists proposing new GW observatories also want to have a simple tool to estimate how different design parameters (e.g., arm length of the interferometer, laser power) will influence the scientific outcomes. Gravitational wave toolbox is a project that will eventually provide the needed tools. The ultimate form of the toolbox will be a website. With it people can easily get the answers for the above questions.

Coffee and tea will be served 20 minutes prior to the seminar.

Anyone interested is welcome to attend.
