Title: Light deflection in General Relativity: From the exoplanet detection to exploring gravitational waves
Date/Time: October 31, 2018 / 13:40 - 14:30
Place: FENS L056
Abstract: In this talk, I will introduce the light deflection so-called gravitational lensing in general relativity. The gravitational lensing is a powerful technique to probe the dark objects in the universe, from the galactic to the cosmological scales. In this talk, I will discuss the application of gravitational microlensing to probe the dark matter inside the Milky-Way halo and its recent application for exploring exoplanets. Every year, with survey telescopes almost 3000 microlensing events are explored towards the Galactic Bulge and the follow-up telescopes identify those events with the exoplanet signals. Then I will introduce the proposal of using microlensing for Extra-Terrestrial Intelligent (ETI) with the follow-up observations in the radio wavelength. Finally, I will discuss the application of the wave optics feature of gravitational lensing to probe the gravitational waves.
