摘要 (Abstract):
Extremely large mass-ratio inspirals (XMRIs) are among the most promising sources of GWs that will be detected by the future space-based detectors such as the Laser Interferometer Space Antenna (LISA), TianQin or Taiji. Understading their formation channels and their orbital properties is key in determining their event rates and will also help in the development of accurate templates for their detection. In this talk I introduce the physical processes that lead to the formation of an XMRI, the derivation of the event rates and the number of XMRIs we can expect in our galactic centre. I will also show that by detecting a single XMRI we can measure the mass and spin of SgrA*, the supermassive black hole at the centre of our galaxy, with a very high accuracy.
主讲人简介 (Speaker's CV):
Veronica Vazquez Aceves, obtained her bachelors and Master degree at the National Autonomous University of Mexico. She obtained her Ph.D at the Institute of Applied Mathematics of the Chinese Academy of Sciences. She study binary systems of compact objects and their gravitational wave emission, the dynamical aspects that lead to the formation of inspiraling systems that will be detectable by the future space-based detectors, and the environmental aspects that can affect their formation and their gravitational waves emission.
